Some theories about increased need for D3;
- conversion of D3 to active -OH forms requires magnesium, carbohydrate and gluten or phytates can deplete magnesium
- low fat diet or poor fat absorption could reduce uptake, espcially from supplements which may not contain enough oil; try adding lecithin.
- inflammation, cancer or chronic viral infection may cause vitamin D “sink” in immune cells, which take up vit D to use in interferon activity. Thus less of the total vit D pool would appear in the plasma.
- vitamin D can also be broken down by sunlight, which prevents excess accumulating from UVB; perhaps some is being broken down by oxidative stress or by other catabolic processes.

Re “Consequently, I reduced my D-3 intake to 6000 IU/day. Expecting to find my number leveling off, I had a test this week. To my surprise, the report was 25.3.
How could it be that I supplemented with a high level of D-3 over this extended period, and yet reverted to a reading of only 25.3 ng/mL”
Could be test error. However levels can vary depending on your body’s requirements for anti inflammatory antioxidant reserves at 53ng/ml your body was only just building up a reserve. See Dr Davis’s Track your Plaque post called TOPPING UP YOUR VITAMIN D TANK and you’ll see he finds his patients take much longer than one would imagine to really fill the tank so he can reduce intake. I think maybe you were a bit premature though I am surprised at the size of the drop.

There are firms offering home 25(OH)D testing. Grassrootshealth.net and The vitamin d council bother offer this service. I think Dr Davis at Track Your Plaque does and in the USA there are also discountlab testing places that may offer 25(OH)D tests on special offer from time to time if your insurance won’t. I think most people will be surprised how low their 25(OH)D level is even if they spend time in the sunshine. Vitamin D is made of of the same precursor substances also used to create cholesterol so those following a cholesterol lowering diet or therapy may be less able to generate vitamin D3 when exposed to UVB.

My view is that everyone should get tested and keep on testing every 6 months until they understand how much vitamin D from supplements their body requires. The spread of response to any daily intake is tremendous so unless you test you won’t know if your a high/low/medium responder.
I keep my 25(OH)D at around 60ng/ml throughout the year with 5000iu/daily and plenty of FULL BODY sunshine. I live at latitude 52 and am now not obese but it took me far to long to realise (when I was obese) I needed more vitamin d than normal weight people.

Maybe this is a really basic question, but how do you know what your Vitamin D levels are? Can you test it yourself at home? I live in the Southwest where we get plenty of sunshine, but I’d be interested in testing if I was to start using megadoses of vitamin D, especially when treating illness.

Thanks!

II became interested in Vitamin D last year. I had my blood tested in August 2009 and the results were a disappointing 30.1 ng/mL. So, I took 8000 IU/day for four months and had my blood tested again in January 2010, and my number was 53.4. Consequently, I reduced my D-3 intake to 6000 IU/day. Expecting to find my number leveling off, I had a test this week. To my surprise, the report was 25.3.

And vice versa; perhaps vitamin C fills some of the holes in the flu-vitamin D link; sailors would have been supplemented with vitamin C (from citrus) in 1918, the rest of the European population would have been in semi-scurvy, due to naval blockades and rationing.
Combine low Vit C (very low by todays standards, when ascorbate is even an antioxidant in junk food) with low vit D and a new virus, you have the perfect storm of 1918.
They have recently shown that low mega-dose vit C does protect against colds in cold climates, so Pauling was right about the skiers.
