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:
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!
