Why krill oil?
A few days ago I posted on a fish oil/krill oil/curcumin regimen that I’ve been using to treat joint and muscle soreness after golf. I had a number of comments wanting to know about krill oil and why I made it part of the treatment protocol. Your wish is my command.
Krill oil, logically enough, comes from krill, which are small, shrimp like crustaceans that inhabit the cold ocean areas of the world, primarily the Antarctic and North Pacific Oceans. Despite their small size–one to five centimeters in length–krill make up the largest animal biomass on the planet. According to Neptune Technologies, the Canadian company that holds the patent for krill oil extraction, there are approximately 500 million tons of krill roaming around in these northern seas, 110,000 tons of which are harvested annually.
A krill, in profile
Krill oil, like fish oil, contains both of the omega-3 fats eicosapentanoic acid (EPA) and docosahexanoic acid (DHA), but hooked together in a different form. In fish oil these omega-3 fatty acids are found in the triglyceride form whereas in krill oil they are hooked up in a double chain phospholipid structure. (The fats in our own cell walls are in the phospholipid form.) Attached to the EPA leg of the phospholipid is a molecule of astaxanthin, an extremely potent anti-oxidant. The phospholipid structure of the EPA and DHA in krill oil makes them much more absorbable and allows for a much easier entrance into the mitochondria and the cellular nucleus. In addition to EPA and DHA krill oil contains a complex phospholipid profile including phosphatidylcholine, a potent source of reductive-stress-reducing choline, which also acts as a natural emulsifier.
Krill oil contains vitamin E, vitamin A, vitamin D and canthaxanthin, which is, like astaxanthin, a potent anti-oxidant. The anti-oxidant potency of krill oil is such that when compared to fish oil in tems of ORAC (Oxygen radical absorptance capacity) values it was found to be 48 times more potent than fish oil.
The astaxanthin found in krill oil provides excellent protection against ultravoilet light and UV-induced skin damage. It was for this reason that I started taking krill oil to begin with–I only discovered its other virtues later on.
A number of studies have shown that krill oil is tremendously effective in reducing LDL-cholesterol, raising HDL-cholesterol, and lowering blood sugar. It has been shown to be effective in treating the pain and inflammation from rheumatoid arthritis and aches and pains in general. One large study showed that krill oil has tremendous benefits in terms of symptom reduction in PMS and dysmenorrhea. And it has been shown to be effective in the treatment of adult ADHD. In all these studies krill oil was tested against fish oil and not simply a placebo.
Due to the rapid absorption of krill oil and the high anti-oxidant content there is virtually never the fishy burping and aftertaste sometimes experienced with fish oil. And there are no other side effects to speak of. The jury is out right now on if and to what degree there is a problem for those people allergic to shrimp. Until the jury is in, I would be careful in taking krill oil if I had a shrimp allergy.
Are there any downsides to this miracle substance? Only one. It is a little more pricey than fish oil, but, as with all things, you get what you pay for. Virtually all krill oil is produced by Neptune Technologies and shipped to the various supplement manufacturers, so any krill oil you get will have come from the same place and be the same dosage. The only unknown is how long it has been sitting around in a warehouse somewhere, which is, of course, the same unkown with fish oil. At least with krill oil, thanks to the high anti-oxidant content, the shelf life is much longer.
One last thing. I neglected to mention in my previous post that popping a couple of fish oil and krill oil caps don’t give the same immediate relief as popping a NSAID. It takes a while–a couple of weeks in my case–for the fish oil/krill oil to provide the same degree of pain relief as the NSAID. So, the take home message is: don’t take your first dose and compare it to the relief you got with a dose of NSAID. If you do, you will not believe the program works and will probably think me an idiot. It takes a while, so give it time. In the study I mentioned in the last post, the subjects took the fish oil for two weeks along with their NSAIDs, then tapered off the drugs and treated their pain with the fish oil alone.
Hi! That was a great post with a lot of good information. I noticed in your last entry that you’re continuing to take fish oil along with the krill oil. After reading your current entry that struck me because the phospholipid form sounds much better. Is it because you can’t get EPA/DHA in sufficient quantities from krill oil without getting excessive amounts of vitamins/antioxidants?
Hi Tad–
No, I’m not worried about excess vitamins/antioxidants with the krill oil. I take the fish oil in addition just to get a little more of the good fats in a less expensive form. I figure that there is plenty of antioxidant in the krill oil to cover the EPA and DHA in the fish oil.

Great post Mike but I can’t seem to purchase the products online at their web site? Any ideas on how to buy the stuff?
Hi Fred–
Neptune Technologies doesn’t sell directly to the public, but it produces all the krill oil that is for sale out there. I’ve seen it at health food stores, Whole Foods and other natural food markets, and a million places online. It is called Neptune Krill Oil or NKO. Since it all comes from the same place, shop based on price. We are currently looking for a source so that we can put it on our website.
Best–
Mike
I spotted the NKO at Whole Foods last night and it’s currently on sale. I would have picked up a couple of bottles but didn’t have my checkbook with me so I’m going to go back this weekend and get some. I believe that the tag said the sale price is good until 8/1/06. I can’t recall the price off-hand (I have a hard time remembering numbers) but had just been looking up prices on NKO yesterday afternoon and it was definitely cheaper than what I had been looking at. I’m going to give the curcumin a try, too.
Also, I have a question. Just how much fish oil should one take? I currently take 3 caps a day of the Carlson Norwegian Salmon Oil. I used to take 6 until I read somewhere that that was too many but other sources say 6 is ok so I’m getting rather confused. Thanks for posting about GLA. I think I must have read the same thing about it that you did and started to take it but based on what you’ve said, I’ve eliminated it. Also, what do you think of flax? A lot of folks are crazy about it but I can’t eat the ground meal as it triggers my IBS symptoms and the oil is rather pricey and it’s my understanding that the fish oil is better anyway. Thanks!
Hi Esther–
You don’t really have to take a lot of fish oil to get the benefit from it. As I posted, I’m taking two fish oil and two krill oil capsules per day, which is probably about all I would recommend.
If you’re on a low-carb diet I would avoid the GLA.
I don’t think a whole lot of flax. The fatty acids you need are the EPA and the DHA, neither of which the flax contains; your body has to convert the particular type of omega-3 contained in flax oil into fats. If you’re ill, or getting a little old, or diabetic, o have any number of problems your conversion apparatus doesn’t work optimally so you don’t get the amounts of EPA and DHA you need from the flax oil. Why not let the fish or krill do the conversion for you and get the EPA and DHA already formed?

Oh I forgot to mention that the makers of MarineOmega actually send someone from their company to examine the Krill for perfection before they agree to buy .
Hi, I get a lot of nasty aftertaste/reflux from fish oil caps(and I’m on Prevacid for a hiatal hernia). Is this true of krill?
Thanks.
Hi Elaine–
One of the many virtues of krill oil is that it doesn’t have the problem of fishy reflux/burping/aftertaste. Because of its phospholipid structure the krill oil absorbs much more rapidly, and because of the high concentration of anti-oxidants the oil stays fresh. I would give it a try.
If you want to try a different fish oil, try Nordic Naturals. It’s the only brand I’ve ever used that virtually never gives ‘fishy’ reflux.

My husband tried to take fish oil and it made him sick (not sure what kind of sick) however the flax oil doesn’t so he has been taking that. He has heart disease with one blocked artery and is on a whole mess of pills.

I read the rheumatoid arthritis extract. It seems that I could reduce my daily intake of 10 grams of fish oil to 3 grams of krill oil. This assumption is based on the finding that 1 gram of krill oil was more effective than 3 grams of fish oil.
I found another supplier of krill oil. NSI at vitacost.com. I was delighted to calculate that the daily cost of krill oil would only rise to 39 cents a day from 25 cents/day for fish oil.
Unfortunately, the NSI oil is not as potent, with 1/3 the EPA per gram and almost 1/4 the DHA. And the Astaxanthin is 2 mg versus 15 mg. So the low-cost NSI krill oil is probably not as effective as Neptune.
Probably my solution will be to take a combination of krill oil and fish oil. The prospect of improvements in lipoproteins and glucose control seem worth the trouble.
Hi Dave–
Keep me posted on how you do.

About the Neptune astaxanthin 15mg level. I was misled by a label typo. I believe that 1.5 mg is correct for Neptune.
Hello.
Doesn’t krill oil contain Omega 6? Are you concerned at all about ingesting any additional Omega 6?
Thanks.
Hi Diana–
There is a minuscule amount of omega-6 in krill oil, which is no big deal because there is so much more omega-3. It’s the ratio of the two that matters. Most foods contain some omega-6. Even a beef steak will have a little. Don’t worry about the tiny bit in krill oil.

Hi Dr. Mike! I’ve really been enjoying your blog. I hadn’t heard of krill oil before, and it is fascinating (although far out of reach of my budget at this time, unfortunately). I can see that the krill oil (and/or a cold water fish BODY oil) would be a *better* choice, but do you and MDE still consider the Carlson’s (lemon-flavored) cod liver oil to be a decent product? I took 1 tablespoon per day for a number of years until I couldn’t afford it any more, and I hope to be able to squeeze it back into my budget pretty soon here.
Hi Donna–
Yes, we still think that Carlson’s cod liver oil is fine. At the time we recommended it we couldn’t find any fish oil capsules that we thought were good (i.e., lacking in peroxidized oils); now there are a number of fish oils out there that qualify.

i was wondering about mercury (heavy metal) content in the krill oil - how does it compare to say Carlson’s or Nordic Naturals’ CLO? my concern is a child with mercury-related autism. thanks!
Hi Louise–
Don’t worry about the mercury, heavy metals, etc. because there are none. Krill, due to their size and the fact that they are at the bottom of the food chain, have virtually no contaminants. The oil extraction process of Neptune Technologies gets out anything that may be there. I would have no hesitation using Neptune krill oil with a patient with autism. In fact, I suspect it would help.

hi, i have a question. Is there any experience with intake of krill oil by autistic infants? In terms of effective doses, and margins to them maximum intake/day).
On parents’ forum, I found NKO mentioned occasionally as an interesting option yet I haven’t found any scientific publication on the subject.
My concern is with my autistic daughter who is 2 1/2 years of age and 14 kilo’s body weight.
Hi Ben–
I’ve read one paper that was a case report of an autistic girl (I’m pretty sure it was a girl because I remember thinking when I read the paper how few girls are autistic compared to boys) who made pretty remarkable improvement on krill oil. I don’t know if she had been tried on fish oil first and then switched to krill oil or had simply been put on krill oil to begin with.
It certainly wouldn’t hurt to give the krill oil a try. I would puncture one of the gel caps a squirt the contents into something your daughter likes to eat and mix it in. One capsule about 4 or 5 times per week should be plenty.
If you haven’t read them yet, a couple of pretty good sources on treatment of autism are:
The Natural Medicine Guide to Autism by Stephanie Marohn This book can be had through Amazon.com and found in bookstores.
Biological Treatments for Autism and PDD by William Shaw, MD. This book you can find at the following site: http://www.greatplainslaboratory.com. Great Plains Lab does a lot of the testing for various parameters checked in autistic kids.
Good luck. Keep me posted.
MRE
Dr. Mike,
After reading your excellent article on Krill oil, I simply had to research it myself, and spent several hours on the internet this morning. I am convinced it is far superior to traditional fish oil capsules. It’s too bad it never caught on in the marketplace. My local health food store, Lindbergs, said they sold it a few years ago but it never caught on, so they stopped selling it!
Two other stores in my immediate area do carry it - Whole Foods, and a smaller health food store, so I bought some. However, you and your readers might be interested to know that I just found out amazon.com is selling different brands of krill oil at amazing prices - half of what I paid for it today at the store.
Just thought I’d let you know in case you want to pass on the word.

Hi Ms. De Jong–
I can’t make specific medical recommendations, but I can say that in my case and those of others posting comments here the addition of krill oil helps.
Krill oil contains a number of anti-inflammatory agents along with the EPA and DHA. making it a more potent anti-inflammatory agent that plain cod liver oil.

Dr. Mike,
I just read an alarming report on Jean Carper’s blog. I cut and past the email address for you:
http://www.jeancarper.com/newsflash/1727 - 18k
In it she says that all the benefits I’m reading about krill oil are a lot of hype, and that regular fish oil is more beneficial. In this blog she states that fish oil is a better source of antioxidants than krill oil and cites CoQ10, etc. in fish oil. But isn’t the CoQ10 she talks about,an ADDED antioxidant? It is my understanding that Krill oil contains it’s own NATURAL antioxidants. She also says that krill oil is a much less potent source of fish oil, and what we’re reading in the press is bunk, more or less.
She goes on to state that there are only two studies done to back up krill oil, done by the manufacturer, whereas fish oil has 40 years of studies to back it up.
Dr. Mike, please give your opinion of this. I realize that Jean Carper is a medical journalist only reporting what she finds. Please say it ain’t true! From what I read, I was very impressed with the benefits of krill oil and the double blind studies they used. Also, it’s my understanding it takes less of krill oil to do what a higher amount of regular fish oil can do in one’s system.
Dr. Mike, what do you think?

Thanks for all the good dope on krill. I has angina starting in 2002 getting steadily worse. In July 2003 I started taking 6 caps a day of Res-Q 1250 (fish oil concentrated with 750mg of EPA and DHA in each 1250mg pill) and 2 of LDLX, a red rice yeast, as recommended and sold by http://www.n3inc.com They promised that my total cholesterol would come down in 8 weeks (it did from 240 to 160) and that after that my arteries would start cleaning out.
In 12/2003 my angina peaked, I got a nuclear stress test and was invited to have an angiogram the next week. I declined and hoped that Res-Q would work. By 10/2004 my angina had disappeared. This past march I had a 64 slice CT scan which disclosed that I had one 50% block of hard placque (calcium) and several soft blocks of about 20-30%. The doc said my arteries were as good as most 30 year olds (I am 70). The 64 slice machine is as good if not better than an angiogram (the pictures show exactly where blockage is and precisely how severe a block. I could see for myself. I highly recommend that everyone with any doubt get 64 slice CT scan (machines are about a year old now) or wait a year or more for the next version, a 128 or 256 slice which will really be accurate. Takes about 6 minutes.
I don’t quite understand why you still take fish oil as well as the krill. Is this a cost issue only or if not why not take 3 krill instead?
Best regards, Ben
Hi Ben–
Good question. Although the krill works at lesser doses, I continue to take the fish oil just because the studies on heart rhythm were all done with fish oil. I guess I’m just trying to cover all my bases. If I were going to take just one supplement, though, it would definitely be the krill oil.
I’m glad to hear of your success with the fish oil. Keep it up.

Hi Doc,
I have been doing alot of research on the net about Krill oil and couldn’t find anything negative about it.I have eaten shrimp all my life and on rare occasions i have experienced a mild itching between my fingers but that’s about it and i have been to an allergist who tested me for allergy to shrimp and they told me i showed an allergic reaction on my skin.They said i should not eat shrimps or lobsters but i have been consuming these products all my life with no serious side effects.My question to you is could i take krill oil in small amount and gradually build up my dosages over a period of weeks or months? I would appreciate any advice you can give me on how to build up my tolerance to this great product. Thank you.

Hi Max–
If you’ve been eating shrimp and lobster all your life without problems, I doubt that the krill oil will bother you. I would be careful just the same and maybe puncture one of the caplets and try a tiny dose first (a fraction of a caplet–it doesn’t’ taste bad) and work up from there. Remember, anaphylactic reactions can be fatal, so if you’ve had a problem, I would recommend that you should try your first ‘dose’ with someone present.

Hello,
I started taking krill oil shortly (1 month) before I discovered Mike’s info on it here. It seems it may have helped with some agravating knee pain I was experiencing the past couple years.
I was suprised to find out that all “NKO” krill oil is manufactured by the same source. So it’s ok to “shop based on price” assuming they store it properly. I did some researching and bought from the cheapest (reputable looking) source at $20 shipped. But I noticed a stronger fishy smell with this brand, although it is also NKO krill oil, with a year left on the expiration date.
I did the bite test and it doesn’t taste good, but bearable. Got a slight bad aftertaste. Didn’t bite test the first brand for comparison (already used up). So I don’t know if that’s just how krill oil always tastes. Also noticed the softgel is almost hard instead of flexible like the other brand. I’m thinking it’s not spoiled, but perhaps less fresh. I’m not sure though. Considering throwing it out to be on the safe side and buying from the first place again (which sells in higher volume, so fresher maybe). What’s everyone elses experience with the NKO krill oil softgels?
Hi Rich–
The type we use originate–as do they all–from Neptune Technologies. I’ve never yet gotten a batch that had a unpleasant smell. Since you purchased yours for about $20, which is the cheapest I’ve ever seen them, I wonder if Neptune off loaded a bunch that were a little long in the tooth for a low, low price? I don’t know; I’m just speculating.

Hi Mike M.D.
Thanks for the feedback on your experience. Have you ever come across NKO softgels that are hard (not flexible to touch)? I contacted the company about returning for a refund (awaiting their response).

I bought Jarrow brand krill that was shipped cross country during heat spell last summer. The stuff smelled badly when I opened first bottle. The nutritionist at the company claimed the product was not damaged by the heat and that product does have strong odor anyway. I had some stomach problems after taking 50 or so tablets at one a day. Don’t know if the krill caused it but I have been trying to get refund on the other full bottle to no avail. The company rep will not return my phone calls. I was hoping for quick resolution of this so that I could order another bottle in this cooler weather.

Hi Mike M.D.
I was wondering if you still refrigerate your krill oil in a glass bottle (as mentioned at http://www.proteinpower.com/drmike/?p=148). I noticed that it says on the product page for krill oil (on this site) not to refrigerate. I’ve heard conflict on this from other sites as well (saying different things) and I’m confused.
Some say don’t refrigerate at all, others say refrigerate, and others say refrigerate during long-term storage (such as when you have multiple bottles not being used), but not when being used since it supposedly absorbs better at room temperature. Will refrigeration damage the capsules or krill oil?
Sincerely,
Rich
Hi Rich–
We have always refrigerated our fish oil capsules. When we first started taking krill oil we refirgerated that as well. After a week or so the capsules became weepy and gooey and all stuck together. At first I figured it was just a bad bottle, but when I tried another the same thing happened. At about this same time I happeded to run into a vendor for krill oil at a trade show. I told him about this, and he said NOT to refrigerate the capsules. I asked why, and he told me that they shouldn’t be refrigerated because of their phospholipid structure. I’ve been thinking about it and can’t figure out why the phospholipid structure would have anything to do with why the capsules would go bad with refrigeration. But, they did go bad, so we quit refrigerating them, and they’ve been fine since.
We have inquiries in to the scientists at Neptune Technologies and are waiting to hear back. As soon as I do, I will post whatever I find out. Until then, I will continue NOT to refrigerate, and I would recommend the same to you.

I bought some NKO Krill Oil and tried it out for a month. At the same time that I started taking the KO, I stopped taking Spring Valley’s Super Omega Complex with Omega 3, 6 & 9. Why take both, I thought. KO is supposed to be superior.
During that month, my period cramping & PMS intensified & the inflammation in my dry eye syndrome worsened. I decided to return to taking the SOC from Walmart (Walmart’s brand has been rated very high by the Consumer Report Magazine).
My conclusion is that the Krill Oil was NOT superior to the Super Omega Complex in reducing inflammation. (I’ve since read that period cramping is also a result of inflammation.) I have also experimented in the past with taking Fish Oil ONLY compared to taking the SOC. The SOC did a much better job at reducing inflammation than just the fish oil alone. That’s something you don’t hear very often. I read this article on line (by Michael Smith):
“There’s clinical agreement about the overabundance of omega-6 fatty acids in the average American’s diet. It’s not that omega-6s are “bad.” After all, they’re essential nutrients that help stimulate hair and skin growth and regulate metabolism, among other things. …….Proper levels of omega-6, gamma linolenic acid (GLA), can also function as a PMS regulator, immune system strengthener and arthritis inhibitor.
The problem is that, while the American diet does contain an overabundance of omega-6 sources, the oil is most commonly found in processed shortenings and vegetable oils, which the body is incapable of metabolizing into a useful form. It’s like putting diesel fuel into a gasoline-fueled car. The tank may be full, but the car can’t make use of the gas….”
So perhaps the hype about KO stems from the fact that people are not getting enough of the right form of Omega 6, and KO does provide Omega 3, 6 & 9. But in my opinion, you don’t have to buy KO to get the EFAs or “fuel” that your body can use.
Hi Wendy–
Thanks for an alternative viewpoint. Were I you, I would do exactly as you have done; it obviously works for you.
The standard American diet does contain way too much omega-6 fats, many of which are NOT partially hydrogenated, and the body can use them just fine. The problem is the ratio of omega-6 to omega-3, not just the overall levels of either.
Because of its phospholipid structure, I believe krill oil is better absorbable and will provide more rapid benefit to more people than fish oil.
Thanks for writing.

I tried the Krill oil, 1.5g/d just as in the study, and use genuine “Neptune” product. After 4 months - Trig down from 105 to 90. HDL no meaningful change (from 41 to 39), LDL no meaningful change (from 165 to 168). All of the studies looked great, but the product just didn’t work in the real world. Suggest to everyone that you wait until there are meaningful studies in “real” peer-reviewed medical journals that don’t have ties to the supplement industry before you thrust your whole future into this one.
It of course could be that I was the one out of 1000 that just didn’t respond. Or, perhaps it just isn’t all it is cracked up to be.
Hi Tsobs–
I would never recommend krill oil for its cholesterol altering properties, although in your case it did seem to work to lower the most important parameter of all: triglyceride levels (which in your case fell from 105 to 90). I recommended krill oil as an anti-inflammatory for back and joint pain. I don’t really care what it does to cholesterol levels because I don’t believe that cholesterol levels mean squat.

If you think you have been diagnosed with a possible heart blockage you had better consult and treat with an M.D. cardiologist, not a “homeopathy Dr.” who is treating your condition with Krill oil capsules. There is not a shred of evidence anywhere that this Krill oil is going to “clean your arteries” of a blockage!!!! This kind of advice is going to land you in the cemetery. Dr. Eades - please comment, this person’s life may be at risk.
Hi Tsobs–
I can’t ethically get in the middle of this. It goes without saying that any and all should seek the advice of qualified physicians for serious health problems. Many MD physicians believe in and practice homeopathy, even some cardiologists, I would suspect. I can’t recommend physicians and I can’t prescribe and I can’t recommend for or against other physician’s treatment plans online.

I’ve always had pretty dry skin and some asthma; and don’t carry any extra weight. I started taking krill because fish oils seemed too strong and led me to the bathroom often. But after taking them for a couple months now, for the first time in my life I have oily skin and am breaking out.
The anti inflammation affects have been terrific for breathing in the cold winter weather, but it looks like I may have to cut back to one a day for skin purposes. Have you run into this? Julie
Hi Julie–
No, I haven’t experienced this problem. Were I you, I would cut my dose back a little to see if I could find a dose that provides enough anti-inflammation to keep your asthma in check yet doesn’t cause the oil skin. You might try adding about 500 mg of circumin per day to the reduced krill oil regimen. The circumim will intensify the anti-inflammatory effect, but should affect your skin.

I try to keep up with health matters but I’ve not heard of curcumim - what is it and where might I find it?
Thanks much* Julie
Hi Julie–
Circumin is an extract of turmeric. It has great anti-inflammatory properties. We will ultimately have it for sale on our website, but you can purchase it at any health food store or online. I take 500 mg per day, but many people with serious inflammatory problems take much more.

It’s great to be able to discuss the pros and cons of something like krill oil on this site, since some health issues are simply not that easy to find reliable information on.** Since reading an above note that mentioned the smell of krill oil, I decided to cut open one of our krill oil capsules. These are red in color and quite firm (swansons) … and the smell wasn’t very pleasant. HOW could you know if these aren’t fresh … or if it’s not in your best interest to take them ?? thanks - Julie
Hi Julie–
Krill oil is more stinky or fishy smelling than fish oil. I just got in a fresh bottle, so I opened a gelcap and smelled it–it did indeed have a fishy odor. I then chewed a gelcap and it didn’t taste too bad.
With the technology we have today, I would guess that krill oil would be good for at least a year. I did a test with mine in the refrigerator after transferring them from a plastic bottle into a glass bottle. After doing this and keeping them in the fridge for two weeks, they were fine. I think the oozing that comes from refrigeration while in plastic bottles comes from the humidity that penetrates the plastic bottles.

I have recently started the krill (NPO) capsules; however, I have also been taking cod liver oil (1 teaspoon a day). My question is: Is this too much oil? Can’t vitamin A or D build up in the liver and become toxic?
Brenda McDowell
Hi Brenda–
Most of the A and D comes from the cod liver oil, and one teaspoon per day won’t give you enough to worry about, assuming you’re not taking other supplements with large amounts of A and D.

My son, who had a kidney transplant a year ago, is allowed to take typical, reasonable doses of fish oil. Would he be able to substitute krill, or does it act on the immune system in more powerful ways than fish oil does?

I was talking to a trainer at the gym where I workout. He said he’s been taking krill for the purpose of losing weight, and he has. He said he takes 2 tablets or capsules at lunch time and does it for 10 days, then goes off for 15 days, then repeats the cycle but takes 3 a day. What do you recommend? I’m 41, have always had a low % bodyfat, but I feel my metabolism slowing down. I still workout 3-4 days a week, including 20-30 min of cardio. I can’t seem to trim the waist area with the ease that I used to. Will Krill help?
Thanks, John
Hi John–
Krill oil contains long-chain polyunsaturated fats. It has been shown that these fats have a lipolytic (fat breakdown) effect, but I’m not sure there is enough in a couple of krill oil softgels per day to effect much lipolysis.
The single best way I’ve found to get rid of excess fat around the waist in a hurry is to go on almost an all-meat diet. Such a diet is high in leucine, which is required to build muscle, and low in carbohydrates. Carbohydrates increase lipogenesis (the build up of fat), so decreasing them does the opposite and stimulates fat burning.
Hope this helps.

I have been taking MarineOmega for a little over a year. One month ago I stopped taking it and started with Nature’s Made Fish Oil tablets (this contains no Krill oil). I have noticed that I don’t feel as “alert” anymore, and sometimes I really have to concentrate on things. Could this be that the MarineOmega has 100mg of NKO and the new tablets don’t contain any Krill Oil?
I have bought a bottle of Twinlab Cardio Krill Oil to see if I notice any difference. Can different combined amounts of EPA/DHA produce this effect?
Thanks, Marie
Hi Marie–
I’m not familiar with any of the brands you have been taking so I don’t know about their EPA/DHA dosages. I do know that krill oil has a different fatty acid structure that allows it to be absorbed better and have a more potent effect.
I would try adding a krill oil softgel to your new fish oil capsules and see if the problem goes away.

Amazing Info !!
Ok Doctor. I am sure you have heard this before, but I had a unique situation and I’d like your opinion.
I am 28, 6″3 220lbs, been in athletic shape all my life, but have had several joints dis-located, fingers broken, knuckles shifts, lower back pain etc …
In other words, I feel like I got hit by a truck somedays, others I don’t feel any pain. I work with my hands for 30 minutes and I get pains up the sides and “flaming” feeling in the muscles of the hands. Did the “arthritis” tests and according to the doctors, they were negative.
krill can help ?
Hi Shaun–
It has worked for many others. Take a look at the rest of the comments to this post and others on krill. I would take the curcumin along with it.
It won’t work overnight; it takes a couple of weeks of taking the regimen, but once it kicks in, it works pretty well for most.
Keep me posted.

Thanks for this very informative posting on NKO. I’m interested in krill oil primarily for its heart health effects and was most intrigued by your statement in the posting that “A number of studies have shown that krill oil is tremendously effective in reducing LDL-cholesterol, raising HDL-cholesterol, and lowering blood sugar.” But later, in response to a comment by someone whose experience did not bear this out, you said, “I would never recommend krill oil for its cholesterol altering properties . . . I don’t really care what it does to cholesterol levels because I don’t believe that cholesterol levels mean squat.”
I’m convinced that blood lipid particle profiles are meaningful for people with CHD and anything that does increase HDL to the extent claimed in the one study I’ve found that was sponsored by Neptune would be a remarkable product. Unfortunately, I can’t find any study other than the one study they sponsored. I’m surprised that there has been no further study of these properties of krill oil (especially given all the studies on fish oil, which also cannot be patented), and am wondering if there are in fact “numerous” studies showing the cholesterol effects or is there just the one?
Hi Warren–
You wrote:
I’m just as convinced that it doesn’t matter. And since I don’t think it really matters I don’t spend a lot of time searching for papers showing that this compound or that reduces cholesterol.
You have sort of caught me out on the krill oil papers. I wrote that I had seen numerous papers showing that krill oil reduced cholesterol, raised HDL-cholesterol, etc, but I really haven’t as far as krill oil specifically is concerned. Because of its phospholipid structure, krill oil is kind of a supercharged fish oil (i.e., it has the same fats as fish oil but structured in such a way as to make absorption much better giving much more bang for the specific fat buck), so I was considering papers I had read showing the advantages of fish oil as being also applicable to krill oil.
I don’t know if you’ve seen this paper (pdf file) or not, the krill oil was provided by Neptume Technologies, but the study itself was done at McGill University, a prestigious Canadian university.
Cheers–
MRE
Thanks for your feedback.
When I say that I am convinced that blood lipid profiles matter, I am not talking about total cholesterol levels, or even the interpolated LDL number, but rather, some of the more specific measures, such as small, dense LDL (which is pretty widely believed to cause artery damage), high triglycerides, and low HDL (particularly large particle HDL), as well as LpA. I agree with what you stated in a recent post:
“If any components of the whole constellation of lipids do end up being involved in the development of heart disease, they will be triglycerides, HDL (the so-called ‘good’ cholesterol), and small dense LDL particles. Ideally, you want to have a lot of HDL, low triglyceride levels, and low levels of small, dense LDL particles. How does one achieve that? Easy. With a good quality whole-food low-carb diet. Restricting carbs decreases triglyceride levels, increasing fat increases HDL levels, and at least a dozen studies have shown that switching to a low-carb diet reduces the levels of small, dense LDL particles.”
If krill really has the incredible impact on HDL that the McGill University study showed, that could be pretty exciting. I’ll probably try it and see whether it helps raise my HDL levels.
Hi Warren–
Keep me posted. I’m eager to learn your results.

Hello Dr.Eades…I have read this particular subject (on here) with much enthusiasm, since I just ordered the oil and wanted to know more about krill oil….I also have been reading about a French dermatologist that has been researching what he calls a “marine lecithin” for the benefit of people with psoriasis! In reading his literature on line and various articles on the web it sounds as though krill oil and the “marine lecithin” are the same!?
http://www.psoriacalm.com/engl/
this quote stuck out for me implying some people lack an enzyme in the liver which may bring on the disease of psoriasis? because of the lack of lecithin?
“So without making it a medicine, we can treat psoriasis simply by compensating what might simply be a disease due to the lack of lecithin induced by an enzymatic deficit of the liver.”
Hi Sally–
Yes, krill oil and marine lecithin are the same.
I’m not sure I agree with the ’science’ as related to the causes and ‘cures’ for psoriasis in the link you included. But if krill oil works to reduce the symptoms, who cares what the underlying mechanism is?
Keep me posted if you try it.

I’ve purchased my first bottle of NKO Krill oil, and will begin taking it soon. Presently I’ve been taking fish oil and read in a magazine by the name of Radius, that fish oil can cause gastinal/intestinal problems due to it turning rancid in the system. I researched the info read in Radius but was unable to find it written anywhere else, unfortunately, I read the magazine in a fall avoidance office while waiting for my Dad so can’t pick up the book and find the origin. Have you ever heard of this problem with fish oil? Also have you heard if Krill can help the elderly brain function?
Thanks in advance, It was interesting to read all the posts.
Hi Bill–
You don’t have to worry about the fish oil turning rancid in your body; you have to worry about the fish oil turning rancid before it gets in your body. A misconception has arisen about fish oil because a lot of people have fishy burps after taking it. The reason is that some people have a little difficulty in absorbing it. The same is not true of krill oil due to its different structure. It contains the same long-chain polyunsaturated fats as fish oil does, it’s just that their hooked up differently in a way that virtually everyone can absorb better. So you get the same oils without the burping.
Cheers–

Thanks for the quick reply. The last bottle of fish oil caps I bought had fairly firm caps and at the time I thought nothing of it, but through your posts I see that I should have been concerned and possibly I could have taken some fish oil that is not so new, so what would be symptoms of rancid fish oil? Since reading your posts, I have discontinued use of these caps. Lastly one question I asked at the end of my last post was: Would Krill oil help the elderly in brain function in any way?
Hi Bill–
There aren’t really any symptoms from taking rancid fish oil. It would gobble up some of your endogenous antioxidant capacity to deal with it, but you wouldn’t notice this as a symptom.
Yes, krill oil will definitely help an aging brain. It helps mine a lot.

There is much literature out there on omega-3 oils and mental health.

I understand that you don’t believe in the significance of cholesterol numbers, but many (in fact, most) physicians and researchers do. Was wondering if ANY reader of this blog has actually had ANY increase in HDL or decrease in LDL or TC from using Krill oil. It did nothing for me personally, I’m interested in knowing if others have had results.
I’ll throw it out to the crowd.
Hello to everybody. My name is Mike and i’m from Belgium (sorry my english is not very good) and i want to post some questions and a message. A few days ago i bought my first krill oil. It has the smell of fishfood and the smell is not bad at all. When i bite into one and chew it, it taste like a nutral oil. It doesn’t has a bad taste.
Questions:
1. Can i suppose now that my krill oil is ok?
2. What is the tast of rancid krill oil?
A friend of my had a total cholesterol of 300 before he used krill oil. After six months of krill oil it went down to 189.

I have read in the medical supplies of dr. Mike that rancid fish oil convert to harmful oxidized fats and that it is necessary to take vitamin E to neutralise the lipid peroxides.
But what about krill oil, krill oil has a lot of neutral antioxidants, is it necessary to take vitamin E with the krill oil? And if it is necessary how much do you have to take? Is 30mg/day enough?
Hi John–
The many antioxidants contained in krill oil is one of its major virtues. I don’t think it requires any additional vitamin E, but it probably won’t hurt if you take a little extra.

Dear Dr. Mike
My Cholesterol has gone down with one a day Lescol 80 xl. Moved recently. New GP doctor has suggest adding fish oil. I do have occasional (not sustained) rapid heartbeat….going for stress test end of Sept.
Upon looking into fish oil I came upon something that said do not take or take only with Dr supervision. I will discuss further with my Cardiologist. I did not see this comment when I looked into Krill oil. Would you know if the lack of this comment was possibly do to the fact that Krill has not been studied in as much depth of fish oil, or is there something different about Krill that would not cause any concerns.
Thank you for any input you might have about this.
Hi Marilyn–
It’s a good idea to check with your cardiologist about the krill oil as well. It’s always good to keep your doctor in the loop about all supplements as well as prescription drugs. Krill oil doesn’t have many of the effects of fish oil because the doses needed to achieve a desire effect are so much lower. The reason is that the omega-3 fats in krill oil (which are the same ones in fish oil) are hooked up differently so that they absorb much, much better. So, in essence, you get the fish oil effect without so much fish oil.
Hope this helps.

Here are my results after one week krill oil.

Dear dr. Mike,
You wrote “Some of the changes - although in the right direction - could have simply been within the limits of lab variation.” Is it possible to explain this a little? Do you want to say that my results are not exact?
Thank you.
If you had blood drawn and sent half the sample to the lab for analysis, then sent the other half for the same analysis, you would get slightly different readings for each even though both are the same blood sample. The techniques used by commercial labs aren’t that precise, so there is some variation. If you get a cholesterol reading one time of 205 mg/dL and the next time it’s 197 mg/dL it doesn’t necessarily mean that your cholesterol has fallen. It could just be within the limits of normal lab variation.
Hope this explains it.
Cheers–

Something i forgot to mention, the bloodanalysis were done in the same lab.
Doesn’t matter. The variation is in the imperfection of the laboratory process.
Hi Dr. (2) quick questions:
My wife is 6 months pregnant, and was curious if krill oil is ok, or if you ever heard of any adverse effects of krill oil on pregnancy. (Were trying to make our baby smart is possible, while helping with some of her back pain)…
2) Do you know of any krill oil in liquid form? If not, do you just open the gel caps and take it that way? Any recommendations to kill the smell/taste?
Thanks Doc!

Hi Ken–
Krill oil should be fine during pregnancy, but your wife should let her doc know what she’s taking. One of the fats in krill oil (and fish oil), DHA, is one of the two fats essential for the developing fetal brain. The other is arachadonic acid, so I always tell my pregnant patients to eat red meat to get plenty of this essential fatty acid.
I don’t know of any krill oil that comes in liquid form. Maybe other readers have found a source and can let us both know. You can open the caps and take it that way, but if it’s in date, I would just take the caps.

Dear Sir,
I really enjoyed reading all the questions and Answers, regarding Krill Oil.
I could never imagine NOT supplying my body with Krill Oil. I am 35 years old and have lived a healthy active life, I love life and intend keeping active and healthy as long as possible. Most readers will think at 35 years old, you should be well and active; However, I have 4 children and 1 on the way, I have a stressfull Job within the Oil and Gas Industry as well as set 6 World Records in Endurance Motorcycling.
I have been very lucky with illnesses over the last 35 years, suffering only broken bones and fractures due to an active Sports life.
I do not profit from Sales or Marketing of Krill products, However I wish I did, because taking Krill Oil has without a shadow of doubt shown me fantastic results:
1: I have not been sick with flu or a common cold for over 2 years.
2:My skin is constantly clear.
3:No aches or pains in muscles or joints.
4:Dont have headaches.
5:Never moody.
6:Loads of energy.
7:Great Sex life.
8:Always posotive.
I could list 50 more things, but you get the point.I would highly recommend Krill oil to anyone thinking of trying the product. Like me you will see great results.

with food, in between meals, before bed…?

I keep my krill oil on a temperature between 14 - 16 degrees. But when i bite on it, the oil is no longer liquid for 100%. Is it possible that the oil has coagulated a little?
The highly unsaturated fats in krill oil are like any other fats - they become less fluid as their temperature drops. Krill oil at 14-16 degrees will indeed become a little more solid, but it’s nothing to worry about.

I just recieved my first order of Anartic Krill Oil from Dr. Mercola’s web site.
Has anyone found this Krill Oil to be a good choice?
In response to Tom, all Neptune Krill Oil comes from the same lab (Neptune Labs in Canada). Dr. Eades here says to buy the one that you get the best deal on, because NKO is NKO regardless who the reseller is.
It’s a bit amusing how Mercola goes on to say to not waste your money on other products because his product is extracted from the real “Neptune Krill.” There is no such thing as “Neptune Krill.”
Aggressive marketing aside, I did notice a good sale price a few weeks ago, but I didn’t act on it.
First off, great info on Krill. I’m 63 and been taking fish oil from Trader Joe’s for 15 years. I started taking it for the purpose of helping to lower my cholesterol. Helped a little but I keep on taking it. Now thinking of adding Krill for same reason and additionally for help with my tendinitis in my elbow (golf).
Two questions: Why do you not believe in lower cholesterol levels as a way to lower chances of heart attack since the entire planet seems to believe that lowering your cholesterol will keep you from a heart attack for a longer period of time and will Krill help relieve pain from tendinitis?
Thanks for your time.
Hi Rit–
Enter the term lipid hypothesis into the search function on this blog and you’ll learn why I feel the way I do about cholesterol. I do think krill oil will help with tendinitis. Especially if you use it like I do with 800 mg curcumin.

Dr. Mike,
i am a 41 year old woman who was quite active the first 2/3 of my life. I played up to 5 hours of tennis a day. However, I had several car accidents which resulted in neck and back injuries and I recently had a microdiscectomy/laminectomy at L4/L5. I still have a significant amount of aches and pains and pretty significant PMS symptoms. I am still trying to conceive a child, which is a challenge at my age. I take synthroid and need to refill my prenatal vitamins. I have just started researching the Krill Oil and am looking at trying it to see if it will help my aches and pains and PMS. Are there any other supplements or vitamins you recommend I take in addition to the Krill Oil. How much Krill Oil should I take and can you provide a link for the Neptune technologies brand you use? Also can you tell me more about the circumin and if I should add that as well. I’m not a big fan of taking medication or supplements so I want to keep my supplements to a minimum. I guess you could say I’m trying to get the most bang for my buck. Plus, I have always had trouble swallowing pills so the fewer I have to take the better. Thanks doc.
Hi Eileen–
Here is an early post I wrote on krill oil that should answer most of your questions. There are other suppliers of krill oil now besides Neptune Technologies. Any of the commercially available brands should be fine.
If the krill oil doesn’t completely do the job, you might think of adding circumen. It helped me. I take about 800 mg per day.

Dr. Mike,
Can you tell me anything about Zyflamend softgels by New Chapter in treating inflammation and joint pain. I was wondering if I should try this product or just use the Curcumin you described. I found the NKO fish oil at whole foods and the zyflmend. Both have warnings on them if you are trying to conceive or if pregnant. Would you let your wife take any of these supplements if she were trying to conceive or was pregnant. You input is appreciated. Thanks.
Hi Eileen–
I’m a little bit familiar with the Zyflamend softgels. In my opinion the krill oil/curcumin is a better option. As to the pregnancy warnings…if my wife were pregnant I probably wouldn’t have her take the Zyflamend, mainly because I don’t know how a number of the ingredients would affect the fetus. I probably would have her take some krill oil, however. But, that doesn’t mean I’m recommending it to you. You need to check with your own physician.

Dr. Mike,
I have been taking Krill oil since March. One of the things that endorsed it for me is when I went in to have one of my 3 dental cleanings per year, my hygenist asked if I was doing something different as the tissue in one problem area had improved. Nothing has ever effected my gum tissue so I had to attribute it to the Krill. I’ve also noticed an improvement in the “pre-beats” I occasionally get in my heart. My questions are: why is it recommended on the bottle to take it with the morning meal-any particular reason you know of and do you think it matters? 2) I’ve been taking one daily(500mg) but am thinking of upping it to 2 a day for 1000mg. I weigh about 165#s-do you think this makes sense?
Thanks, Judy
Hi Judy–
I don’t think it much matters when you take it. And I don’t think it would be a problem to up your dose to two per day if you think that will help with symptoms you may be having. If you’re not having any problems, though, I might stick with just the one.

Dear Dr. Mike,
I have been recommending omega-3 (EPA/DHA) to my patients for years for both HDL/LDL ratio management and joint pain management with great success. Of course the fishy reflux is a commonly reported side-effect which sounds easily remedied with Krill Oil and taking supplements with meals.
I’ve recently had a couple of hunters relate they they are concerned about the increase in body odor from taking fish oil. Will Krill Oil potentially diminish this effect as well?

The krill oil will definitely get rid of the fishy reflux and should get rid of the body odor as well.

Dear Dr. Mike,
I have two questions? I’m 38yr old and in good health. I’m taking krill oil during five months now. And i feel good. Should i take the krill oil every day (1cap=500mg) for the rest of my life or is it better to take a cure (3 months krill and then 3months nothing…)?
Is it true that krill oil reduces oxidative stress?
Thanks, Mike.
I take krill oil daily and have been for a while because I don’t eat a lot of fish. It will not hurt you to take a krill oil softgel daily.
Does krill oil reduce oxidative stress? A difficult question. The omega-3 oils in krill oil actually increase oxidative stress because of their multiple double bonds. But the antioxidants in the krill oil reduce oxidative stress. And the omega-3 fats can ultimately be converted to anti-inflammatory substances. So, it is a mixed answer, I guess. Overall, I would say that krill oil reduces inflammation.

Thanks for the answer dr. Mike.
But increase the omega-3 oils (from fish or fishoil) always the oxidative stress or is it only the omega-3 oils in krill oil?
And if omega-3 oils in fish or krill oil increase oxidative stress, is this not a problem for our health, because oxidative stress is not something good, i suppose?
Thanks, Mike.
The increase in oxidative stress is probably a little greater with the fish oil for a couple of reasons. First, you have to take more of them to get the same effect provided with smaller doses of krill. Second, the fish oil doesn’t contain the antioxidants that the krill oil does.

hey doc…
just wondering…. i was at a convention about a year ago with barry sears (zone diet) and he recommended that we simply ‘guzzle’ fish oil to help with what he termed ’silent inflammation’ in the body. What is your take on this and how krill oil might affect this silent inflammation in comparison to regular fish oil…
also, how is it you came to recommend circumin over say a ggt (garlic, ginge, tumeric) therapy and why?
I think krill oil would help fight it better because it’s better absorbed and you don’t have to take so much of it. The fatty acids in fish oil and krill oil are easily oxidized, and if you ‘guzzle’ it you are asking your body to use resources to stabilize this oil that could be better used in fighting inflammation other places. A little fish oil is good - too much can be problematic.
I recommend circumin because it has worked well for me and for a number of my patients who haven’t had the same success with garlic and ginger. Circumin is the active ingredient in tumeric.

INFORMATION TO ALL: Costco has just announced they will have Krill Oil available in their
vitamin aisles beginning in January. They say in their magazine “What is small, red and 3X more powerful than fish oil” for supporting cardiovascular health. It shows a photo of a much smaller caplet than the fish oil we see. This was in their December 2007 Costco Connection magazine. Volume 22 * Number 12. Hopefully a better price and perhaps fresher product due to their huge volume.
A QUESTION: I just had a 64 SLICE heart scan showing some blockage. My rating was in the mid 500’s on the scale. Then I scheduled and had a nuclear stress EKG And nuclear scan. They advise me that the blockage I have in 2 arteries isn’t bad and I should just be careful about diet and get some regular exercise, lose some weight, the normal stuff. The cardiologist told me it is not reversible. Is that true. Can I hope for some reversal or, of course, just protect what I have?
You should discuss this with your physician. I don’t know anything about your specific case. I do know that in studies it has been shown that some blockage can be reversed.

Just found your blog info on krill oil, and wanted to add my thanks to the others. Our postal clerk suggested I look into krill oil for arthritis. I have had problems with degenerative osteoarthritis in my spine and both hands. This sounds like something that perhaps may help the pain and soreness that goes with it! Worth a try.
Thanks, Sherrey

I have been purchasing my supplements from Swanson vitamins for the past year and I am very happy with them.
Can you eat too much omega-3? I’ve recently discovered your blog and am reading it so much my eyes hurt! It has propelled me into eating real, whole, foods and fish (and meats) will be a much bigger part of my diet. Regarding the krill oil and fish oil caplets: I currently take 2 Nordic Natural Omega-3 softgels per day(as does my 13 year old son), and I will definitely add the krill oil capsules to this. I also want to add fresh salmon roe to my diet (I discovered this while eating sushi… it’s called ‘ikura’ in the sushi restaurants). It’s expensive but since I’m cutting out all the crap I’ve been eating for snacks, it’s a treat I will reward myself with frequently - I happen to love it and would it huge amounts of it daily if I could afford it! Do you think that one can get too much Omega-3? … if I eat a few spoonfuls (like 3 or 4 teaspoons….1 to 2 oz I think that would be??) of salmon roe every other day in addition to the NN Omega-3 and the krill oil… am I getting too much omega-3? Just as a reference, one website that sells the salmon roe says “Ikura boasts remarkably high levels of omega-3s (EPA and DHA), averaging 1,800 mg per ounce (USDA figure). This is only a bit less omega-3 fatty acids than occurs in a 3.5 oz serving of King Salmon”.
Thanks, and I’m telling everyone I know about your site!

Hi Lina–
I think one can eat too much omega-3 fat. An overconsumption of omega-3s can lead to bleeding problems among other things. Stefansson reported that during his years living with the Eskimo that they suffered from spontaneous nose bleeds frequently. I think that omega-3s are kind of a Goldilocks and the Three Bears deals: you don’t want too little, and you don’t want too much - you want just the right amount. Which, of course, varies from person to person.

I want to begin taking Krill Oil. I have 24 years old. Am I too young to take it or is it fine? I currently take HealthPak 100 which doesn’t have Omega3. Will taking Krill oil help keep my skin smooth and also help with my brains like eating fish? Thanks ALso, is it possible to consume too much on a daily basis?
As far as I’m concerned, no one is too young to take krill oil. As to what it will do for your skin and brain - anything fish oil will do, krill oil will do at a lower dose. And as with anything, too much can cause some problems. But taking a gelcap or two per day should be fine.
What do you think of http://www.swansonvitamins.com/ProductDisplay/catalogId/10051/productId/17288/R/9323&SourceCode=INTA016&saleCatalogId=10051 Which is Nature’s Way Krill oil, I notice it has twice the amount of Omega3 vs. the regular swason and price is the same, should I just go with this one?
It looks like a decent product to me, but all I have to go on is what the ad says. I’ve never done a hands-on evaluation of this product.
I just saw that Costco is now carrying MegaRed brand from Schiff that is NKO oil. It’s 90 300 mg caps for $18.99… It’s the best price I’ve seen so far.
Mega Red Krill Oil from Schiff should have a warning label:
PEOPLE WITH ALLERGIES MAY EXPERIENCE:
* Blurred vision
* Itchy Eyes
* Sleep disorders
* Cold sweats
* Other allergic reactions typically caused by shrimp
After purchasing the bottle of 90 caps at Costco, took only 3 days for me to suffer all the aforementioned, which I have NEVER suffered during the years I’ve taken Omega 3 capsules made from fish oil.
KRILL ARE NOT FISH. They are shellfish similar to shrimp which Schiff does not tell you ANYWHERE on their labeling.
I also purchased MegaReds at Costco. The shellfish warning is listed in two places. You have to have good eyesight, which I don,t have, to read it.
Hi Doc,
I have been taking krill oil for about a year and a half now. I first read about krill oil on Dr. Mercola’s website and have been taking it ever since. I have a book on healthy aging which has alot of information on types of foods we need to consume as well as supplements we need to take in order to slow the aging process. One of the supplements they mention is Coenzyme 10 which i have been taking for the past year now. One of the chapters in this book mentions the importance of fish or krill oil and coenzyme 10 together. I know this blog is about krill oil, but i wonder if you any information about this enzyme.
A treatise on CoQ10 is way beyond the scope of the comments section. You can find all the info you want on it online or in our book The Protein Power LifePlan.

What should be the daily dosage of krill oil. I’m taking 2 500MG to load up for 30 days and should a 300mg after that be enough or stick with the 500mg a day.
Since I don’t know you or know your medical history and your medical condition, I couldn’t possibly make a recommendation. For most people one softgel per day will do the trick.
Dear Dr. Mike,
I have a question about the capsules. Of what are they made? Can the capsules cause health problems over the long term?
Some are made of gelatin, others of vegetable material. Neither should cause any long term problems.
i have been taking krill oil for about 4 months now, 500mg per day and have had a 2/3 rd’s decrease in my triglycerides, previously i was taking 3000mg of salmon oil per day- it had little effect on my lipids but i still take it. krill oil is expensive but in my opinion well worth the price
It’s more costly but more potent as well. If you compare potency per dollar it probably comes out to be cheaper than fish oil.
I find this whole approach quite ridiculous. Our granparents generation called it “eating high off the hog”, meaning, only eating the most rare, expensive, hard to find, best.
Why do we have to put yet more species in endangerment because we are now going to eat their only supply of food?
We don’t have to do this. I wish persons such as yourself would be more sensible, and environmentally responsible.
I doubt seriously that the great biomass of krill are in danger of being depleted. But thanks for the advice.
Dear Dr Mike,
I’ve been taking NKO for over 18 months and each different batch I’ve bought (from 2 different suppliers, all smell really fishy when you open the cap to the bottle. When you break open a capsule the smell is the same, no worse. The smell itself is not repulsive, just extremely fishy like a box of kippers or shrimp you might hav ekept in the frige fo r acouple of days. Is this normal or would rancid oil actually smell awful and be immediately apparent, e.g like shrimp you threw in the garbage can 3 or 4 days ago?
Also, did you ever hear back from your suppliers about why you shouldn’t refridgerate. I know one person you spoke to said certain bonds might be affected but you couldn’t see how that might be.
for krill oil the fishy smell isn’t bothersome - that’s just the way they smell. Fish oil has that smell only if it’s starting to oxidize, but krill oil smells that way when it’s fresh.
The refrigeration isn’t a problem because of the cold. It’s because of the moisture. If the bottles the softgels are in is permeable the moisture in the fridge is going to penetrate and make the softgels sticky. If you keep them in glass bottles (or some of the plastic bottles we’ve gotten them in) they don’t get sticky even in the fridge.
I have been taking Schiff’s MegaRed Krill oil for over a month now and I love it. They are so small and they actually smell good. I have never had any fishy after taste. I also give it to my children (9 & 6). Thanks for leading us to it. Best one out there!
I bought the MegaRed for my husband, who is allergic to freshwater fish. I am now going pick up a bottle for myself. Thanks for great blog!
Thanks for reading.
Just purchased a bottle of 500mg krill oil,exp. date 2010.They are very hard, can barely make a dent pressing with my finger. I am not worrying about rancid but wonder if these will even disolve. You have answered this elsewhere but I can’t find it. Should they actually be soft? Thanks.
Most of them are pretty firm - at least the ones I use are. They are much harder than large fish oil capsules.
I’m a vegetarian so I don’t use krill oil for myself, but I have been giving it to my dog, along with a homemade diet. Do you think that would be better for him than fish oil as well?
I have been taking Water4Life V-Pure vegetarian EPA & DHA supplements. http://www.water4.net Have you heard of them before…I’m curious if you think they are legit, or if I’m just wasting my money? Thanks.
I think krill oil will work fine for your dog - it’s just expensive.
Many companies sell EPA and DHA supplements that are produced from algae, and are therefore vegetarian. I don’t know anything about Water4Life, so I can’t comment.
I have been taking 2 softgels 1000mg each as dictated on the Krill Oil from Mercolas site. Is that too much would one softgel do? I am taking for general health purposes. Do you know if it interferes with asborption of synthroid? many thanks
It shouldn’t cause a problem.
What is the difference between res-Q 1250 and Krill Oil. I’ve been taken Krill Oil for about 2 months, and what wonders. A friend of mine has been taken res-Q 1250 several years. I’m told that res-Q is better. Confused

90 MegaRed Krill oil softgels sell at Costco in Hawaii for only $15.99, and Costco prices in Hawaii are usually higher than the mainland. $5.00/month is cheap enouch compared to fish oil
I noticed you told Ken, - 21. September 2007, 23:08, that krill oil is fine for his pregnant wife. All the krill oil products state emphatically that it should not be taken while pregnant. Do you know the reason for this? What specifically are they guarding against. I have been taking fish oil and am thinking of switching to krill oil but I am hesitant to do so with such a blatant warning on the bottle.
Most products - even natural products - have warnings against their use in pregnancy because they haven’t been tested in pregnant women.
Is there any iodine in Krill Oil? My concern is that iodine can sometimes aggravate adult acne according to some studies. Anything about krill oil that might cause or aggravate acne in middle age adults?
Nothing I know of that could aggravate acne.
After reading an article David Mendose wrote about krill oil, I started taking 1,000mg daily for about three months. I use the NSI brand from Vita-Cost (very reasonably priced): http://www.vitacost.com/NSI-KriaXanthin-Antarctic-Krill-Oil-with-Natural-Astaxanthin-1000-mg-300-Softgels
Two years ago I was diagnosed with osteoarthritis of my right knee. The orthopedic doctor told me I was less than ten years away from total knee replacement (I was 53 at the time) as the cartiledge was almost non-existent and my severe debilitating pain was from the bones rubbing together. He prescribed Mobic but it did not help. I used to lie in bed and cry at night because the pain was so bad that I could not get adequate sleep. And I hurt all day long. I was beginning to think I would not make the ten years!
About six weeks after starting the krill oil I noticed my knee was not keeping me awake and my pain had reduced about 50%. Then sometime during this past month I suddenly realized that my pain was nothing more than a slight twinge! I would have to describe the transformation as miraculous.
On a side note, my total cholesterol has gone from 274 to 117. I don’t know if it is the krill oil, my Armour-Thyroid, or a combination of the two.
I have high cholesterol. My last lipid test taken this month was 200 for total cholesterol, 98 for trglyceride, 44 for HDL and 136 for LDL. I have been taking 1500 mg of niaspan for over two years but it does not seem to be lowering my cholesterol. I annnot take statin drugs I have had juvenial diabetes for 52 years. I recently bought a bottle of Schiff Krill oil at Costco. It does not have the same amount of Omega, EPA and DHA as fish oil. My Doctor recommended I take fish oil. Will Krill oil help my cholesterol and lipid problems and should I take one, two or three softgels a day? Also fish oil gives me flatulence.
I don’t know why you think you have high cholesterol. A total cholesterol level is a pretty meaningless test even if elevated, but yours isn’t elevated. 200 is at the high end of what most lipophobes consider normal. Your LDL level is fine as well. Having said all that, the krill oil despite having lower doses of EPA and DHA has the same effect as fish oil and usually with fewer GI symptoms.
Dr. Mike,
I have a really bad food allergy and there are just a few things that I am not allergy to. They are onions, tomatoes, seafoods and apples. There are many problems that are caused due to my food allergy and I have been in the hospital several times in the last year. Do you think that Krill Oil will help me with my problem?
Thank you,

I prefer a more Natural Source of Omega-3.
I recently found http://www.Omezing.net
The product is an ALA derivative from plant. I am a firm believer that my body, void of excess Omega-6, can effectively and efficiently convert ALA into EPA and DHA. I would much rather prefer this than a mercury contaminated fish oil, a poor tasting and foul smelling flax seed product and a high allergen krill oil.
Our bodies are meant to be self sufficient. It is a safe and natural option and I believe a safer one for my family.
Thank you for this great discussion. It has been extremely helpful and informative. I have been taking 4,000 mgs of Omega fish oil for my cholesterol for 5 months. It has helped with LDL but not the HDL. So since I have read so many good things about Krill helping HDL, I would like to try the Krill. But I still want the DHA and EPA benefits as well because I notice a nice difference as far as mental clarity is concerned. But the DHA and EPA are extremely low in the Krill Oil. So if I take half dosage: 2,000 mgs of Omega 3, what would you think would be equivalent to the other 2.000 mgs of the Omega 3 to the Krill Oil, with similar benefits of DHA and EPA? The DHA and EPA in this Omega 3 is 300 mgs. of EPA and 200 mgs. of DHA per gram. Your comment would be very much appreciated.
Keep up the good work!
Thank you,
Joy
I would start with one krill oil gelcap and see what happens. Because of the phospholipid structure of the fat the EPA and DHA in krill seem to be much more potent than their lower doses would indicate. If you don’t get the result you want with one gelcap, move to two.

Hello Doctor!
My mom is 70 and diabetic. She is very thin but has a knee problem. Every time she climbs stairs, it hurts. She is taking fish oil (800mg EPA and 400mg DHA) and lethicin (1000mg, I think) everyday. Seeing all the benefits of krill oil and curcumin, I want to give her krill oil (1000 mg) and curcumin (500mg) per day as well. However, would this be too much for her? I’m kinda concerned about her memory and don’t want to see her having AD someday… Also, I’m 35 and I think my memory is getting terrible! When I need to think, I feel like my brain doesn’t work as fast any more. Any recommendation? Thanks!
I don’t think the krill oil and circumin should be a problem, but you should ask her doc what he/she thinks. You can find a ton of information about preventing AD from Dr. McCleary’s book.
Cheers
I do apologize but my wife insists I ask you a question relating to krill.
She wants to know if in your opinion it is OK for breastfeeding. She intends to swap from her fish oils to krill (somewhat on my advice).
The fact that you already say above that it is ok for pregnancy I expect you will also believe it ok for breastfeeding, but we simply want to re-confirm.
Since your wife isn’t my patient, I can’t give her medical advice. I would counsel one of my own patients that a switch from fish oil to krill oil shouldn’t cause a problem. Your wife should check with her own physician before making any changes in diet or supplementation while breastfeeding.
Just bought Whole Krill / 300mg. Noticed that most are selling Krill Oil. Is there a difference between the two? in The ingredients say each capsule of gelatin contains 300 mg of freeze dried whole krill. First time using Krill and was recommended by a friend. I’m having knee problems ( after surgery) with inflammation (water). Had meniscus repair and removal on May 31.2008. Thanks
I’ve never heard of Whole Krill. That would imply that it is the entire krill crunched up somehow. And I don’t know if that’s what it is or not. Sorry.
Dr. E,
You said that you leave the krill oil out of the refrigerator, but is it OK to do that with fish oil? In PP Lifeplan you say to test it every few days, but do you think the oil is of better quality now and that’s not as necessary?
Thanks
I do think the fish oil capsules available today have a longer shelf life and are better ‘pakaged’ then were the capsules several years ago. Plus, many, many more people take them now than did back then, so there is less chance of inventory sitting around getting oxidized. I keep my fish oil in the fridge, but even then I chew one up every now and then just to check. I’ve yet to find a bad one.
Hello,

Just found this blog because I was trying to find out why Krill oil worked so well for me. It’s was pushed on me by a “health nut” family member who is always advocating healthy stuff (in truth, she was always ahead of her time, taking flaxseed years ago)
Long story short, I was on psychotropics for 13 years (prozac, then lexapro). The one time I tried to go off I “rebounded” so badly I was terrified to try again. Started taking Krill Oil capsules (I think by the “Marine” co. mentioned above), felt “right” somehow, so thought - eh, I’ll try again to get of the psycho tropic. I have been off it for five months, use krill oil, it’s great for mood support, and I’ve coped with a pretty severe medical crisis in my family without ever feeling the need to “medicate”. I have no other health issues but I’m impressed Krill oil got me off Lexapro after all this time.
Glad to hear you’ve done so well. I’ve heard a number of similar stories.

Hello,
I’m a cyclist from Belgium (age39) and i was taking krilloil during 9 months, then i stopped 3weeks and then i restarted. I noticed two big changes.
1. My blood pressure went donw from 125/80 to 110/55.
2. My average heart rate during competition went down with 15-20 heartbeats.
My mother was also taking krilloil during 6 months and her tot. chol. went down from 290 to 230. HDL stayed at 90. Ratio went down from 3.2 to 2.7.
Could you tell me how can we tell how much vitamin E is in the Krill oil if it’s not in the nutrition facts on the bottle? I am now thinking of taking the Schiff’s Mega Red Krill Oil, 300 instead of the 500 mgs. I hope it works better for me! I value your extremely helpful responses. Thanks so much!
This probably won’t be one of those extremely helpful responses because I don’t know how much vitamin E is in there if it isn’t on the label. The primary antioxidant in krill oil is astaxanthin, which gives krill oil its red color. There may not be a lot of vitamin E.

She generally avoids oily foods because she has an upset stomach when she eats oily foods becuase of her Gallstone problem, Just want to make sure , will taking krill Oil cuse any problems or should it be avoided for people with Gall stones?
or would it be ok , since you said that it absorbs quickly , will it be fine ?
Thanks in advance for your reply

I can’t say for sure because your mother-in-law isn’t my patient, and I know nothing about her other than what you’ve told me, which isn’t enough info to allow me to make a judgment. Although a krill oil softgel contain fat, it doesn’t contain much. Maybe she should try one to see what happens. If it bothers her, then you’ll know the answer.
Hi, I just discovered your blog doing some research for my Mom (she’s 86), and would really appreciate your thoughts on the following: She recently started taking Krill Oil (500mg) instead of the Omega 3 she was taking because of what she heard about Krill being better than fish oil and more easily absorbed by the body. She was also taking CoQ10 (for one reason because she takes Lipitor) and a plant-sourced calcium-magnesium product that also contains D3, K1 and K2 (MK-7).
She has always been prone to bruising easily and after about 1 week of taking the above supplements she said she got a bruise on her arm that is probably worse than any one she’s ever had before so she stopped taking everything.
I’ve read you need to be careful taking Krill Oil is you bruise easily, but I really don’t understand why. Is it because Krill Oil thins the blood ? She didn’t have this problem when taking regular Fish Oil. Could it be the combination of Krill, CoQ10, and the Cal-Mag product.
Thanks so very much for your thoughts !!
Because of its phospholipid structure, krill oil is like fish oil on steroids. If she replaced the fish oil with the same amount of krill, she was probably taking too much. I wouldn’t use more than a gelcap per day or maybe even one every other day. Krill oil - like fish oil - does thin the blood. I don’t think the CoQ10 or the Cal-Mag had anything to do with the bruising.
And I can’t resist commenting that lipitor has never ever been shown to be beneficial for women of any age. And studies have shown that elderly people who have higher cholesterol levels live the longest.
Dear dr. Mike,
My question has nothing to do with krill-oil, but what is your idea concerning flaxseed? Should we take it or not?
Thank you very much.
Sandra.
It doesn’t hurt to take it, and it might even do a little good. But it’s not as good as krill oil or even fish oil. The fats we need to get are EPA and DHA. Both fish oil and krill oil contain these two fats. Flaxseed oil does not contain them. Flaxseed oil contains the raw materials to make these fats, and, if everything is working as it’s supposed to, the body can convert the flaxseed oil into EPA and DHA. But my thinking is why take the chance on everything working properly when you can just get the necessary fats directly without having to worry about the conversion process.
There is a lot discussion concerning how to keep the krill oil …not too cold…not too warm. But what is too cold or too warm? I keep my krill oil at 13° and they are not gooey, so assume that’s ok?
Thanks in advance for your reply.
Sandra
That’s fine.
Doc, I normally take 2 krill oil capsules a day (because of back pain) and turmeric also. But, I also love salmon (Vitalchoice) and eat it on a regular basis. Am I getting too much omega 3 in my diet? Thanks for your time.
All the best,
Vincent
If you are taking two krill oil caps daily and eating salmon on a regular basis, I doubt that you’re getting too much omega-3. I wouldn’t worry about it.
I recently saw studies for treating ADHD children with fish oil. I’ve been giving my daughter fish oil, but the pills are so big, I need to hide it in her food. The krill oil pills (I saw at Costco) are much smaller and can be taken easier. Your article said it worked with adult ADHD. Could krill oil be taken instead of fish oil and get the same effects? Also, the EPA and DHA amounts seem very small (less than 100mg). Is the EPA and DHA more potent?
Yes, krill oil is more potent than fish oil even with lower doses of EPA and DHA. It’s all in how these fatty acids are connected. In fish oils these fats are in triglyceride form whereas in krill oil they are in a phospholipid form, which makes for much easier absorption and fewer side effects.
As you mentioned, krill oil has a number of things going for it that make it a superior choice to taking fish oils. One thing to mention is that majority of research on krill oil has been done by Neptune Technologies using Neptune Krill Oil, not generic krill oil.
I believe if patients wish to get results with krill oil, they should look at the research of what kind of krill oil was used. This will make a huge difference in specific responses each individual may receive from this marine supplement.
Just as not all fish oils are the same, not all krill oils are the same. You can buy lower grade fish oils that may contain higher levels of impurities, compared to a higher priced pharmaceutical-grade fish oil that’s been 3rd party-tested to ensure it contains what is written on the bottle label.
Hi Dr.,
I recently bought Dr. Mercola’s “Krill Oil For Women” which has an 500mg/day addition of “Organic cold pressed evening Primrose Oil” do you think this will be a problem for my girlfriend who is approx 2 months pregnant?
If so, is it just the primrose oil which is not advisable, the krill or both?
Also he advises to take a good quality “Full Spectrum” Vitamin E supplement with the Krill Oil, do you have any recommendations brand/store wise?
We truly appreciate your help!
I would avoid anything with evening primrose oil in it. I’ve had patients experience inflammatory-type problems from taking too much evening primrose oil (and it doesn’t take a lot to be too much).
Pregnancy/Back pain and Krill Oil
First, I’d like to share my experience as I took NKO for my 1st pregnancy, which was advised by my OBGYN (a holisticic oriented MD OBGYN), for both the omega 3 supplement and for my chronic low back pain. I was 30 years old at the time, and was always terrified to get pregnant because I was afraid of having accute lumbagos over and over (the kind with the “electrical” spasms, that make you not be able to move and bend for 2 weeks afterwards until healing. And even without getting spasm every day (I would normally about 1 every two months), I had everyday chronic low back pain which would not enable me to do too much housekeepoing or walk for too long, before I needed to sit and curve my back. I must add that my weight/height proportion is normal, and except for that, I am a fit person, eating absolutely very well, mostly organic.
Nevertherless, I started to take 2 soft gels from NKO per day the 1st month as my OBGYN recommended to replenish, then 1 soft gel per day. Let me tell you: I had the best ever pregnancy I could never had wished for !!!! Not back pain, no lumbago. I did re-increased to 2 soft gels per day around the 7th month because I read somewhere that I wasn’st taking enough Omega 3s (at that time, I wasn’t taking any fish oil in addition to the Krill), and a little after increasing the dose back to 2 soft gels again, my back felt even better, while adding the pounds in my belly. And for those who are wondering, my son, now 2 and a half, is a very healthy bright little boy. I do give him cod liver oil since he’s been eating solid food as well, but everything is fine, so I would totally recommend any pregnant lady with back problem to take NKO.
Now, here is my 2sd point, which is now more a question to you. I have been eating shrimps and all kinds of seafood (I’m French, so when I was leaving in France, I would eat fish and many different kind of seafood in addition to shrimps in a regular basis), and never experienced any problem. When I took NKO while pregnant, I did not have any problem. However, I have been having some light eczema coming on and off on my hand’s fingers once in a while since I’m 20 years old. During my pregnancy, all sign of eczema disappeared, I assume probably because generally immune reaction is lowered in pregnant women because the fetus is producing some kind of substance to avoid rejection from the mother (can’t remember how this is named but I remember the purpose is that for the mother not to reject the fetus because the fetus is not part a self). So anyway, no eczema during pregnancy. However, the day my son is born (full term), I had preeclampsia severe Hellp syndrome (I must precise that I was check for 3 days before he was born: no high blood pressure, no protein in the urines, everything looked perfect). I had a difficult back labor vaginal delivery while being under magnesium sulfate IV for pre-eclampsia, and after all, everything went well. But, after he was born, I suddenly developped the eczema back on my fingers, and in a matter of 3 months, my 2 hands were all swollen and reddish and small cut bleeding, no elasticity in my skin hands anymore ….. horrible. While I did lots of allergy testing, including extensive food allergy testing, they came back with lots of allergy positive (about 16 ingredients) but found out that those ingredients were not the one who were bothering me. The ingredients that were NOT listed on the extensive allergy lab test results were the ones that I found out were bothering me (using an elimination diet): all nuts, all citrus fruits… and I’m not sure but I believe Krill Oil, but not shrimps or other seafoods !!! So anyway, I found the answer of my problems on my own and not with the help of any doctor who clearly have no clue how to deal with eczema/food allergy !!!! Anyway, after talking with a midwife before starting my 2sd pregnancy, she thinks that Pre-eclampsia and eczema are both linked because it’s a weak liver problem, and she told me to take dandelion tincture every day. I found out that dandelion enable me to eat my forbidden foods occasionnaly and I would not have a flare of eczema.
So, now, here I am at 33 years old, going to start a 2sd pregnancy. But since I stopped taking NKO for the past 2 years because of my eczema, I have been suffering with low back pain and huge lumbagos more than ever (with caring and holding the baby etc …. it takes lots on the back). So what do I do ? On 1 hand, I won’t be able to have a good back during my 2sd pregnancy if I don’t take NKO, let alone I am very scared if I get a lumbago the day of delivery or just before: I won’t be able to push or sustain the effort. (And I’ve been taking cod liver oil and fish oil since the past 2 years, it does not help at all). Or do I take the NKO anyway, let it have some eczema, take the dandelion (which won’t probably offset entirely the eczema if I take NKO every day). I would go for the NKO and let it have the eczema as my preferred choice, but then I wonder if it might trigger preeclampsia again later.
Well well, you probably won’t have an answer for me but I was just wondering what you thoughts are on this situation. Just to let you know, I’m sure you’re going to advise me to see with my provider but all my providers have no clue at all !!! I have already asked many different kind of M.D / OBGYN. / Back pain specialists etc… Just your thoughts will be welcomed. Thank you for your kind feedback. I’m quite on my own in this situation. Sorry for the long e-mail. Please send me your answer online AND on my e-mail address as well, because I’m not sure if I’ll be able to find where I posted it.
It is true that pregnancy exerts an anti-immune kind of effect. For example, women with sever auto-immune disorders such a rheumatoid arthritis get significant - sometimes even complete - relief during pregnancy. If you are having bad back pain that was relieved during your previous pregnancy by NKO, then it stands to reason that it would do so again. And probably without causing the eczema on your hands due to the pregnancy effect. You could try a little just to see what happens.
Keep me posted.
Do you know if the Krill Oil marketed by the MLM JDPrimium is from Neptune?
I’m not familiar with the company you asked about. Since most krill oil does come from Neptune, however, I would say the odds were good.
Would the garlic supplement I’m taking interfere with Krill oil? I saw it listed in these things to watch out for re Krill oil, and would be interested in your opinion on this:
Side Effects
People with allergies to seafood shouldn’t use krill oil. People with bleeding disorders shouldn’t use krill oil unless under the supervision of a qualified health professional.
Side effects of krill oil may include loose stools, diarrhea or indigestion.
Possible Drug Interactions
People taking blood thinners (anticoagulant or anti-platelet medication), such as aspirin, warfarin (Coumadin), heparin, clopidogrel (Plavix), non-steroidal anti-inflammatory medications (NSAIDS) such as ibuprofen (Motrin, Advil), naproxen (Naprosyn, Aleve) should only use krill oil under a physician’s supervision.
Krill oil should also be used with caution by people taking herbs and supplements that are thought to increase the risk of bleeding, such as ginkgo biloba and garlic.
All oils containing EPA and DHA can cause a little ‘blood thinning.’ These warnings are for people taking prescription blood thinners to be careful adding even more with the krill oil. In my opinion the krill oil thins the blood less than large doses of fish oils, so I would think it would be less of a problem for those taking medications and nutritional supplements that may cause blood thinning. But, as always, if you’re concerned, you should check with your own physician.
The benifits of Krill oil is an interesting one. You really do need to be aware of the metal issues in other from fish oils, i.e. Cod Liver Oil, etc. I am involved in a distribution line for Krill Oil, K48 Omega 3, it is an awesome product that I feel has some amaizing value. Check out the link if you are interested.

Hope this helps some of you out there!

hello, do you know the amount of iodine in krill oil? thank you.
I would suspect that it is very little.
i think quality flaxseed is a decent source of omega-3s for vegetarians and folks alergic to shellfish. it’s not as potent, but would be better than nothing, though i’ve to say that i get insomnia when i take even one capsule of trunature organic flaxseed that’s sold at costco in the pm.
i recognize that w/ my strong supplementation, i’m probably able to convert a higher percentage (say a quarter or so) of the omega-3s into dha and epa. nonetheless, in my experience, my father has single-handedly benefited from taking organic flaxseed from costco. mental clarity to just absolutely glowing skin tone. he takes it with a multivitamin everyday for almost a year now. my father in law can’t take krill capsules w/o getting hives.
i take trunature’s flaxseed in addition to nko, carlson’s medomega (which clocks in at almost 3g per teaspoon) as part of my supplementation regime. so i would definitely keep the *quality* flaxseed option in mind as a viable alternative for folks with special conditions like the ones i mentioned.
folks can find out more about costco’s flaxseed and nko products:

Doc, I read that there is fluoride in Krill Oil, is this true? Appreciate the information.
Vincent
I’ve never heard that, but I’ve never seen a chemical analysis of krill oil.
Can we safely freeze krill oil before taking it?
Yep. We used to freeze ours all the time.
Will taking Krill oil help solve my dry eyes problem? I am taking Fish Oil and
hope to try Krill Oil also. Good idea?
I have no idea. A number of medical problems can cause dry eyes - Sjogren’s syndrome being a common one - and I doubt that krill oil would help with those. You might just want to give it a try to see, though.
My girlfriend has been using Krill oil and trying to get me to use it. But I have one reservation…when I was taking fish oil, it didn’t take too long for my urine to “smell so fishy bad” that I had to spray room freshener after using the bathroom. Will Krill have the same effect? And if so, what can I take (or do) to avoid such a “smelly” reaction? Thanks!
It shouldn’t because of the different way the fatty acids are hooked up. All you can do is give it a try and see.
Greetings,
I am currently taking Omega 3 capsules 3 times daily, I’d like to add Krill oil to my daily regimen. However. I am breastfeeding and I’d like to know if adding the krill oil would be safe to do so.
Thanks!
I don’t see why not. But since I don’t know you or know your medical history, it would probably be best for you to check with your own physician to make sure.
why is it recommended to not take nsaid with fish oil?
rodger
Some people think it may thin the blood too much. I’ve never seen a problem with it. I took both when I was switching over from NSAIDs to my fish oil/krill oil regimen.
I note you state that people with an allergy to shrimp should take care when using Krill oil. I am allergic to crab (most severely to Dungeness), but eat shrimp and scallops frequently without any problems. Is it the iodine that is generally present in shellfish that is the problem, or is it a true allergy to something unique only to shrimp that causes the problems? Would it be safe to start with small, infrequent doses to see if there is a problem, and gradually build up to the recommended dosage if no problems occur, or would you recommend staying away completely? The health benefits seem wonderful - but not at the risk of hives, or worse.
Typically people are allergic to one of the proteins in shrimp. There shouldn’t be a problem with krill oil, but if you want to make sure, just try a little of it, and work up from there. You can even puncture one of the capsules and rub some onto the inside of your arm to see if any redness and/or itching ensues. If so, that’s an indication that you are allergic to krill and should avoid it.
Shopping for krill oil, I see a lot of products on the market that are NOT Neptune krill oil. The ones I have seen appear to be priced significantly cheaper at first glance because you get more oil for less money. But when I look at what I’m buying on a cost per gram (of omega-3s) basis, the Neptune oil ends up being slightly less expensive.
Hi Dr. Eades
I want to thank you. You are full of good information. I tried taking two quality fish oil pills and two krill oil pills for a few weeks. This works GREAT.
My joints feel really good, very lose and flexible.
What fish oil pills do you recommend ? Is Carlson’s and the type you use better quality than Whole Foods Fish Oil ?
I just don’t want to use junk as far as fish oil .
(Neptune is what I use for krill so I know it’s good)
Take Care,
Razwell
I think both Carlson’s and Whole Foods fish oils are fine. All you’ve got to do is chew a capsule every now and then to make sure they’re fresh.
Hi Dr. Eades,
I’m absolutely fascinated with all the posts I have read on this site. I am thinking about taking krill oil pills for my rheumatoid arthritis as well as my high cholestrol. I have a hard time swallowing or chewing big pills (it makes me gag) and I saw that Schill had a new megared krill oil pill that was much smaller. I’d appreciate any comments on the quality of the Schill and how much of it I should take each day.
Any input would be greatly appreciated!
I’m sorry to say that I don’t know anything about the Schill krill oil. Most, but not all, comes from Neptune Technologies, so if the Schill comes from there, it will be of high quality. But, it is probably okay even if it comes from another producer, but I just can’t say for sure.
MegaRed is from Schiff and is from Neptune Tech. I just purchased it in one of the major pharm chains. The price was $29.99 for 60, it was on sale as buy one get one free, so I took advantage of the sale, then I found it again in Sam’s Bulk Store for $17.97 for 90. I have just started taking the krill. My Diabetes Dr. recommended I take fish oil. You have to take so many fish oil a day, I decided to try the Krill. What is the recommended mg per day??
Depends on what one is taking it for. I now take one softgel per day.
My Dr. recommended it for my cholesteral, but I am diabetic and I have Arthritis so I want to cover all basis. Right now I am taking 1 softgel per day. I have only been taking them for about 1 week. I noticed that I sleep better and do have more energy during the day. I’m hoping for even better results in the coming weeks. My blood sugar readings are pretty much the same so far and I won’t have any blood work for at least another month.
I’m interested in krill oil I’ve been taking fish oil and flax seed oil for awhile. I’m taking warfarin for my atrial fib and wonder if this would affect my blood thinner. Would it replace the other oils? My doctor knows about them but haven’t discussed this krill oil yet.
Yes, it should replace the other oils. I wouldn’t take it in addition without discussing it with your physician.
I take cod liver oil in winter and fish oil in summer months. I am allergic to soft shell crabs but have no problem with shrimp and lobster. Would it be safe for me to take krill oil?
Thanks,
Shelley
Probably, but you’ll have to test a little to be sure.
Dr Eades
Is up to 3 krill oil pills every other day still safe if you take no medicines ? I’m trying to get a strong anti inflammatory effect.
Take Care,
Razwell
Shouldn’t be a problem.
Hi Doctor,
You recently posted you take 1 softgel a day. How many mgs are in that 1 softgel.
Thanks
500 kg krill oil per softgel.
Hi,
I am new to this and have read through the posts–very interesting, and I would like to start taking krill oil.
question related to taking Ibuprofen: While taking krill oil regularly, can you take ibuprofen on occasion, without risk?
I have been taking advil pm so i can sleep through the night, but may switch to something else, if the krill oil makes me feel better.
I am menopausal, and my dr. recommended to take flax seed oil….can you take both krill and flaxseed oil and are there different benefits from each, or would it be unnecessary to take both?
Thanks
I would go with the krill oil and not the flax seed oil. And it is okay to take with ibuprofen.
Doc,
In your recent post on March 14th, you said “kg” ,but I believe you meant “mg” right? So what is the maximum recommended dose 500mg or can you take more without negative effects? Will 800mg or 1000mg be ok?
“500 kg krill oil per softgel.”
SM
Sorry. My bad. It is 500 mg per softgel. 800-1000mg can be taken with no problem.
Hi Doctor E.
I recently started taking the Mega Red trying to reduce LDL and some arthritis pain. I read somewhere else that taking an aspirin a day may not be a good idea with Krill. I take a baby aspirin a day. What do you think?
Thanks!
Pat
You should check with your own doctor on this, of course, but I don’t think a single baby aspirin with cause much of a problem if taken with krill oil. But, again, I don’t know your medical history, so you should check with your doc on it.
Doctor,
What is the brand that you take? I noticed that you mentioned taking 500mg per day. I thought that Nepture only sold to suppliment distributors in 300mg doses. At least that is what I read you to say back toward the beginning of the blog (but that was back in 06). My daughter works at CVS, and she picked me up some last night from work. The are on sale, 2 for 1 price (29.99) These ones are packaged under the name “MegaRed” by Schiff, 60 softgels at 300mg. Any impressions on this brand?
Steve
I have started taking the NKO (Neptune Krill Oil) variety, which come in 500 mg softgels. NKO is the only krill product that has been studied extensively. Virtually all the investigators writing the papers showing the benefits of krill used NKO for their studies. Neptune Technologies has the patent on the way the company extracts the oil. Other companies have been producing krill oil by other methods that don’t yield the same product, yet making the claims that have been verified only by the NKO product. Do these other products work as well or better? No one knows because they haven’t been studied. They simply use the studies done with NKO to promote their products. For these reasons, we are switching to NKO on our own site. We have no affiliation or investment in Neptune Technologies.
My doctor put me on Fish Oil a few years ago despite the fact I told him I take flax seed which is high in Omega 3. I would like to try this new product as it sounds wonderful. My biggest and only concern is what do krill feed on. Being a Seventh-day Adventist we shy away from lobster, clams, sturgeon, pork all because they are garbage eaters and we feel,
following the Lord’s advice in the Bible the philosophy that “you are what you eat” so consequently keep away from garbage eaters, do krill fall in this category??
As I understand it, krill eat plankton, so I don’t think that would qualify them as garbage eaters.
Hi,
I am allergic to shell fish will krill oil cause an allergic reaction. Also, I live in South Africa and have not been able to find krill oil - do you know if one can import it?
Regards,
Jenny Dugmore
In my experience, no one who claims to be allergic to shellfish has had a reaction to krill oil. I would take it carefully, however, until I knew for sure. I have no idea as to whether it can be imported into South Africa or not.
My doctor told me to take 3 grams of fish oil a day. If I take Krill how many mg of krill will be equivalent to the 3 grams of fish oil.
I don’t know that there has been a dosage equivalency established. I would guess that two of the 500 mg softgels would do it.
Hi Dr. Eades;
I am actually designing a Krill Oil, ubiquinol, mixed tocopherol complex product. Your information on your Krill Oil post is very good. You state that if I liked this post, I can freely share it. Can I have your premission to use some of your writing in my product description that would be on the product web page, but also in product brochures? I obviously would give you proper author credit.
Best regards,
Patrick Bailey
Medicinal Nutraceutics
Be my guest.
I’am keen in krill oil, pls provide spec pls
Hi Patrick Wopuld be interested to hear more on your product development. I currently take mixed tocophs and Krill oil and have been thinking about adding CO enzyme Q10 (which I beilieve is ubiquinol?) as I’m in my mid 50’s and know that this is produced in lower levels as you get older. Question for the good Dr is though, could tocophs and krill thin the blood too much?
Hi Dr. I prev wrote when I started on Krill Oil. My Dr. Recommended I take Fish Oil to help with my Diab and Cholestrol. I chose the Krill Oil and started just prior to my appt. with my Dr. She was not familiar with Krill Oil or its advantages but encouraged me to continue. I have been taking 2 per day. My A1-C has gone from 7. to 6.2. I have had a great deal of relief from Arthritis pain, 2 fingers that were stiff are now alot more flexable. I still have to work on the cholestrol. My question is, would additional Krill Oil be helpfull for that and increase my relief from arthritis pain? And what is the max amount of Krill Oil you can take??
Thank you,
Pat Harvey
It may be a little helpful, but I wouldn’t overdo it. I don’t know what kind you are taking, but if it is the NKO variety, I would say maybe three softgels per day max. Usually the relief comes from taking the krill over a longer period of time, not just by increasing the dose.
I have a serious question. After much research I suggested to a friend to try Dr. Mercola’s Neptune Krill Oil to help lower her cholesterol. She took it for 3 months and recently told me that the “Krill Oil caused her cholesterol to shoot way up by 90 points to a very dangerous level, and she says her boss told her that she was nuts to use krill oil to lower cholesterol, because it is the same as eating tons of shrimp every day. I would very much appreciate any comment you have regarding this. She does smoke, though she quit, she started again, and I have no idea about her other “habits”, but understand she likes fried foods. I seriously do not think that the krill oil is what caused her cholesterol to go up, but am open to any comments you may have. A concerned friend, because after all, I suggested she use krill oil! Van
I seriously doubt that the krill oil had anything to do with her cholesterol. And it certainly isn’t the same as eating tons of shrimp every day. Even if one did eat nothing but shrimp every day, I suspect his/her cholesterol would fall, not rise.
I started taking krill oil a couple months ago, and I started having symptoms of hyperthyroidism. I am going to my Dr. in a day or two to find out what I have. My opinion so far, is that the iodine in krill, along with the iodine in salt( I eat alot of salt) and in my multi-vitamin has brought on these symptoms. I feel that if I do end up having an overactive thyroid, that it should clear up on its own since I’m no longer taking krill oil, salt or my multi. My Dr. will disagree I’m sure, but I don’t want to overdo treatment and end up worse in the long run and “take” something I don’t need.
There should be no iodine in krill oil, or at least not much to speak of. Hyperthyroidism generally isn’t caused by too much iodine anyway. If you are diagnosed as being hyperthyroid, you definitely need to be treated.
Dr. Eades,
Thank you for sharing your blog. In one of your posts there was a mention of when you find the best source for krill oil supplements you would post it. Would you be kind enough to post again?
Thank you for your time and efforts to help educate the layman.
Chuck
After a fairly exhaustive review, I’ve come to the conclusion that the best krill oil out there is produced by Neptune Technologies and sold under a number of brands. All will have on the label the letters NKO, which stands for Neptune krill oil. As a consequence of my review, we changed the krill oil we offer on the product section of our website to NKO, but you can find it many other places.
Thanks Dr. Eades for providing such a great resource for people. I have taken krill oil and fish oil supplements for awhile now and my total cholesterol has gone down about 20%( not that I really care ) but I have noticed fairly prevalent anal leakage during the day. I’ve read that is fairly common but usually only in high doses (which I don’t take). I’ve also read that it could be caused by the quality of the fish oil supplement. What are your opinions regarding this issue?
I’ve never heard of this issue with krill oil. And certainly not with the krill oil I use and recommend. Are you by chance taking Alli, the OTC weight-loss drug? It will certainly cause the problem you describe, as will consuming a fish called escolar, or eating potato chips made with olestra. I suppose some of the fish oil you are taking may be from the escolar. I would switch brands of fish oil, and I would definitely make sure my krill oil had the letters NKO on the label somewhere. NKO stands for Neptune krill oil, which is the purest on the market.
Hi Dr.,
I just started taking Krill Oil today. My question is - what product of fish oil are you taking (or recommend) in conjunction with the Krill Oil. I read that you are taking the Nordic Naturals along with the Krill Oil. There are many listed on their website and just wanted to buy the one that you take and/or recommend
Jason
I use the Nordic Naturals, but I’ve had so much improvement on the krill/Nordic Naturals/Circumin regimen that I now take only a single krill oil softgel and one 800 mg circumin per day.
Thanks Dr. for those updates. Do you use and/or recommend the Ultimate Omega-D3 or another product in the Nordic Naturals line?
I take Pro Omega.
FYI
90 caps of Schiff Red Krill we bought at Sam’s was about $18…. Schiff web site has their bottle of 60 caps @ $25.
My blood pressure is coming done in one week, and some relief in my joints , expecting more..
I have had a problem with severe nosebleeds and try to avoid taking anything with aspirin or nsaids. But, I really like the research on krill oil and my husband has already started taking the supplement several months ago. I also take toprol and arimidex. What would be your recommendation?
I can’t give specific medical advice over the internet. I doubt, however, that a single krill oil softgel would cause a nosebleed. But you should check with your own physician.
Just to let people in this post know, Dr Mercola is now selling his NKO in capsules, so that should eliminate the gel tab problem some people are using.
Hi,
I have a question. I read Dr. Mercola’s articles regulary, and he had a comment on his page where he has krill oil tablets for sale, saying that if you are taking warfarin that you should not take krill oil at the same time. Why is that?
Thank you
Francee
Fish oil and krill oil thin the blood a little. Warfarin is a prescription blood thinner, so adding fish or krill oil to it could thin the blood too much. I don’t think a single krill oil cap a day will make the blood too thin, but you should check with your doctor before you take it.
Krill Oil is an excellent way to decrease inflammation and pain for the weekend warrior. It has so many great health benefits and no real downside like you mentioned. It is good stuff - one thing I would like to add is that Dr. Mercola a very well respected natural Dr. suggests you be wary who you purchase your Krill oil from. He states “be very careful of other’s claims out there”. He says some process the oil using bad manufacturing processes whcih will make the oil less robust.
Dan,
Neptune Krill Oil (NKO) comes from the same lab (Neptune Labs in Canada). Dr. Eades here says to buy the one that you get the best deal on, because NKO is NKO regardless who the reseller is.
It’s a bit amusing how Mercola goes on to say to not waste your money on other products because his product is extracted from the real “Neptune Krill.” There is no such thing as “Neptune Krill.”
Call it aggressive marketing.
Hello Dr. Eades, I am only 22 and I want to bring my cholestrol and trigs down asap. There has been evidence that taking 1-3 GRAMS of krill oil is effective in reducing all this, but krill oil does not contain the EPA/DHA amount like fish oil does. krill oil= 45mg/27mg per tablet while fish oil = 180mg/120mg per tablet. There has also been research that more than 100mg of fish oil has added advantages and is recommended by american heart association for appropriate dosage. Is there anyway I can take about 4 fish oil tablets perday and 4 krill oil tablets perday to get the added advantages? the fish oil will be 1200 mg and krill oil will be about 400 mg of omega 3 for a total of 1600 which isnt really excessive. what do you think because as of right now this is what I am about to start doing.
Because of the way the fatty acids are connected in the krill oil (phospholipid vs triglyceride), the krill oil is much more potent than a similar dose of fish oil.
I find this fascinating, I started a new weight loss and wellness program called Futures Weight Loss & Wellness System. They performed a blood test for immune reaction to foods along with an implementation program and they highly recommend the krill oil product to facilitate inflammation reduction and weight loss. Do you think it would be beneficial to include krill oil in a wellness and weight loss plan?
Absolutely.
Hi,
Can you tell me if taking the Krill and taking approx 3,000 mg of Vitamin D is too much Vitamin D in one’s diet?
It depends on what one’s vitamin D levels are. But, in general, 3,000 IU of vitamin D3 isn’t a problem. And the combination of vitamin D3 and krill oil isn’t a problem.
Hello from England ..
Getting Krill oil is difficult here in the UK ..
It’s obvious health benefits are not recognised and the oil is not stocked by any of the large UK health store chains ..
So I have to purchase my krill oil on-line .. which isn’t usually a problem, except that the bottle of NKO most recently purchased is 3 months past the expiry date ..
Reading your posts, I understand the high antioxidant content of the krill oil will prevent the capsules becoming rancid too quickly .. I know from taking krill oil capsules on a regular basis that they already have a strong taste when bitten, even when fresh .. if they don’t smell or taste completely disgusting, should I consume this latest purchase?
Hello back from England. I’m here myself right now. I’ve got a meeting with Heston Blumenthal today (you’ll know who he is - he’s not well known in the US yet).
I would imagine the krill will be okay. Usually there is a safety factor built into the expiry date, so I wouldn’t worry. But I also would let whomever you bought them from know and maybe wouldn’t order from that source again.
We buy our krill oil from CostCo. It’s called Schiff’s “MegaRed” - “contains genuine NKO Krill Oil…from genuine Antarctic Krill”. $18.95 for 90 300mg gelcaps.
My husband has diabetes. When he takes fish oil, krill oil, evening primrose or Sesathin (sesame oil), his blood sugar readings go up. It has something to do with glycerol being released from fat cells and being used by the liver as a substrate for gluconeogenesis. It is frustrating because he could benefit so much from taking any of these for his neuropathy and heart disease, but the rise in blood sugar is worrisome. I haven’t seen much information on this and it is widely believed that fish oil does not raise your blood sugar. Have you heard this complaint, and do you advise diabetics not to take it if it has that effect?
I doubt that the little bit of glycerol released from the oils your husband is taking are causing his blood sugar rises. I can’t really comment on his situation online. I would have to have much more info. I can say that if your husband is following a low-carb diet, I would recommend that he stop the evening primrose and/or sesame oil.
