Information on the latest vitamin D news and research.

Find out more information on deficiency, supplementation, sun exposure, and how vitamin D relates to your health.

I have very low Vitamin D about 16, I have been taking the 50,000 IU once a week as well as 5000 IU 1x day for the rest of the week. My Vit D level is not improving. I live in a brain fog, with chronic pain from arthritis as well as other issues that Vit D in the "normal" range will cure. Why can't i get my Vit D level up? I have probalby 4-5 years worth of Vit D test info. the very best we were able to get was 21.

    So question one, is the 50,000iu once a week D2 OR D3? I assume the 5000iu is D3?
    Second how much do you weigh?
    Third besides the arthritis, what other issues do you have? Any gastrointestinal issues?
    Fourth what is the largest amount you have ever taken? Right now your average is around 12,000iu but I do not know if that is all D3 or D2 and D3?
