It was only a year ago that the CDC was reporting that men in their 50’s were in need of vitimin D supplements.Now they’re saying just the opposite.

The CDC is a different part of the gov't. The Institute of Medicine, another part, of the National Academy of Sciences, generated this opinion.

From the source:

The report's recommendations take into account nearly 1,000 published studies as well as testimony from scientists and stakeholders. A large amount of evidence, which formed the basis of the new intake values, confirms the roles of calcium and vitamin D in promoting skeletal growth and maintenance and the amounts needed to avoid poor bone health. The committee that wrote the report also reviewed hundreds of studies and reports on other possible health effects of vitamin D, such as protection against cancer, heart disease, autoimmune diseases, and diabetes. While these studies point to possibilities that warrant further investigation, they have yielded conflicting and mixed results and do not offer the evidence needed to confirm that vitamin D has these effects. Rigorous trials that yield consistent results are vital for reaching conclusions, as past experiences have shown. Vitamin E, for example, was believed to protect against heart disease before further studies disproved it.

Whose testimony from scientists and which stakeholders?

Based on available data, almost all individuals get sufficient vitamin D when their blood levels are at or above 20 nanograms per milliliter as it is measured in America, or 50 nanomoles per liter as measured in Canada.

How about some double blind, randomly controlled studies? IMHO, read the entire press release. Half of it is used to identify those on the board who agree with it.

FReepmail me if you want on or off the diabetes ping list.

What's interesting is that we are not told what studies they looked at....were the studies just on D2....which we know does not work the same as D3 (cholecalciferol)??

Check out who is on the 'President's Club' of this outfit and then tell me there is another agenda....
