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.

In France Vitamin D is given by Doctors in oral ampoules of 300,00 to 560,000 iu per ampoule. One is taken every few months. Yes, I got the amounts right. What do you think of this? Does it work at all? I have been worried by it for years. Thanks for any help.

    Well it does work BUT as Dr. Cannell says “it is better to take a little every day, as nature intended” then a whole lot at one time. I also recall some studies that showed smaller amounts each day were better. I suppose if there is no choice, though, then getting something is better than nothing! Even a larger weekly dose would be better than a huge dose every several months.
    We at the VDC recommend 5000iu a day minimum and a blood level at or above 50ng/ml. (125 nm/l).
