To All Readers,

The IOM (Institute of Medicine) report on the Dietary Reference Intakes for Vitamin D and Calcium has just been published.

Their recommendations are below our expectations, specifically, 600 IU/day with an upper limit of 4000 IU/day. The statement was that the only disease they could truly comment on was that of bone health. It should be noted that they were very limited in the types of evidence they considered. The focus was on 'randomized clinical trials' and they set aside many studies that did not fit their narrow definition of evidence.

The GrassrootsHealth Scientists Panel of 41 expert vitamin D researchers and medical practitioners maintain their position based on the evidence that they see that the serum level should be between 40-60 ng/ml (100-150 nmol/L).

We will be posting many quotes from our Vitamin D Expert Scientists on our website, www.grassrootshealth.net/iomquotes during the next few days and you can login and see the latest!

From Dr. Robert Heaney:
"There is an impressive body of scientific evidence supporting levels higher than the IOM panel is currently recommending, and for reasons that are not entirely clear, the panel has discounted that evidence. The public needs to know that that evidence exists so that they can make up their own minds. It's helpful in making those decisions, to know that intakes higher than the IOM recommends are safe. For me, that makes the decision easy. Even if the evidence for a higher intake were uncertain (and I don't believe it is), intakes 2-5 times the IOM recommendations would carry a good chance for benefit at essentially no cost and no risk.

I believe that the presumption of adequacy should rest with vitamin D intakes needed to achieve the serum 25(OH)D values (i.e., 40-60 ng/mL) that prevailed during the evolution of human physiology" Robert P. Heaney, MD, John A. Creighton University Professor, Creighton University.

Thanks again for your participation in the GrassrootsHealth D*action project. This unprecedented grassroots public health movement is changing the health of the world. Thanks for playing such an essential part!

Sunnily yours,
