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 would really appreciate some help please. In this article http://www.nature.com/articles/srep17638 scientists in China state the daily requirement of D3 is 40IU, when the rest of the world says different, please shed some light as 50 times the daily dosage based on their figures and yours varies wildly, here is the quote ' Because the human daily vitamin D dose is (0.5 -1.0 μg) per day'. If anybody can help I know you guys can.

    So I must be blind because I could not find a statement there that talks about the 40iu but this is what I know.
    The US RDA for Vitamin D is 600-800iu a day.
    Vitamin D experts have proved that the human body needs much more than that to function properly. The 600-800iu is only based on bone health and it even falls short in that respect. Vitamin D actually “turns genes on and off” all over the body.
    So, if I remember correctly, Dr. Cannel and/or one of the experts made the statement that humans really need 40iu per pound of body. So for a 150lb person that would be 6000iu a day.
    So here at the VDC we promote 5000iu a day for the average weight person of 150lbs. We promote 1000iu a day per every 25 lbs for children. You can also use that last calculation if you are an adult and weigh more or less than 150lbs. We are promoting more if you are pregnant. We also promote a blood level of a minimum of 50ng/ml.
    Hope this helps!
