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 am taking 8,000 IU of oral D3. I read in Dr. Mercola's newsletter that I should take K2, magnesium, plus calcium. I don't know how much I should take. I have T1D, plus Hasimoto. I am on Tiiodothyronine and Levothyroxine, plus insulin. Thx. Dawn
