I have been using krill oil daily for two weeks, and noticed that my blood pressure has dropped about 10% during those two weeks. No lightheadedness noticed though. Although I am not certain about the connection to krill oil, the change is unusual. I have a read a lot about krill oil, but I have not seen it described as “blood pressure lowering.”

I haven’t either, but it obviously did in your case.

I have been doing a search this morning to find any info on the possible link between fish oil consumption and lightheadedness. I was taking it for about 3 months and during that time suffered lots of lightheadedness/dizziness but did not connect the dots until I ran out and did not get around to replacing for about a month. During this month I was back to normal and that's when the penny dropped. So I have bought more to see if it was s a coincidence. This morning after only about 3 days on it I have woken up feeling lightheaded again. I'm going to stop, leave it go a few weeks and try it again but I do think there may be a connection and was interested to read a couple of the above similar reactions. Does anyone know why this might happen? Could it be reducing blood pressure? Thanks Would be a good question for Dr. McCleary.

I’m reading now where krill oil should not be refrigerated. It should not reach temperatures above 100 or below 50. I’ve had mine in the fridge all this time. It would seem logical to me that since krill come from Antarctic waters, the fridge should pose no problem. Have I ruined my krill oil stash?

Hi Obade–

Nope, you haven’t ruined your krill oil stash.� It should be fine.� I would worry about the heat but not the fridge.

I did the fish oil freezer test: First Vitality says consumers can find out whether their omega-3 supplements contain a high proportion of saturated fat by placing them in the freezer for 24 hours. It says that if the capsules turn cloudy then they could be “capsules of lard”.

I got this statement from:
http://www.nutraingredients.com/news/ng.asp?n=74164-omega-first-vitality-goed-toxins

It also was a report on TV news.

I did the test with krill oil and it froze solid. I don’t know if the same test applies to krill oil. Should I be worried?

Hi Obade–

It’s no problem if the krill oil freezes solid in the freezer.

I just figured out that high doses of cod liver oil are probably causing my lightheadedness, too. I was taking the cod liver oil to counteract a severe adverse reaction to treatment with Ciprofloxacin, but I think I may have overdone it and need to stop for awhile. Glad this site was here, so that I could unravel the mystery.

I’m glad it helped.

regarding fish oil causing lightheadedness/fogginess, i also did enough experimentation with different types and brands, including krill, to know that it was definitely the fish/krill oil causing it. i thought i was the ONLY one! my thoughts were that 1) it could be lowering blood pressure enough to impact the brain, as i noticed postural hypotension. or 2) there may be some sort of vasodilation effect. i haven’t been able to find any answers through research so if if anyone else has any thoughts, i am interested. in the meantime, i suggest the student above take it only a few times a week (not on test day!) which i have found minimizes the brain drain effect.

Hi Susan–

Thanks for the further info.� I’ll keep my ear to the ground to see if I can come up with any info on this situation.

This is good to know- and I was wondering what to do with all my empty coconut oil jars!

Thanks Dr. Eades!

Hi Lyndsey–

Glad to help.

Thanks for the info Dr. Mike! After reading your posts I’ve been taking krill oil for a little over 2 weeks (2 caps a day) and my knees feel much better. They don’t even hurt when going down stairs – which used to hurt way more than going up stairs.

Hi Crystal–

I’m glad the krill oil is working for you.� If it hurts more going down than going up, you’ve probably got chondromalacia, which can be greatly improved by doing quadriceps resistance training.

10 years ago I worked as an artist using water based products (paint, glue, finish, etc.). I used to keep product in both plastic containers and glass mason jars. I then quit working as an artist and packed stuff into storage. After one year everything in plastic was dried up and ruined. After 10 years everything in glass is still as fresh as it was 10 years ago. That's how I learned how valuable glass is. I keep alot of stuff in glass now including dry dog kibble. Hi Mandy-- Thanks for the report.� What you related is pretty much what my photographer friend said, too. Cheers-- MRE�

do you have any recommendations for shelf life. my carlson’s fish oil comes 100 in a bottle, and since i only take it every other day, and switch off with cod liver oil, it lasts almost a year! i cut one open, it just smells…very fishy, so hard to tell if it’s off smelling. for now, krill is still too pricey for me!

FYI–if i take higher doses i experience lightheadedness, don’t know why.

Hi susan–

As to the shelf life issue, I would put them in a glass bottle with an airtight lid and keep them in the fridge.

You’re the second person today to mention lightheadedness with taking omega-3 oils.� As I told the other commenter, I don’t know what could cause that symptom.

Keep me posted as to how you do.
