On July the 28th 2010 the Journal Experimental Biology and Medicine published an article looking at the levels of Vitamin D in the general population and made recommendations concerning the RDA levels needed to limit osteomalacia in adults and rickets in children.[1] This they say is because scientists and nutritionists from many countries agree that at present about half of elderly North Americans and Western Europeans and probably also of the rest of the world are not receiving enough vitamin D to maintain healthy bone. This is nothing new to this web site or indeed the thousands of people that have been following this story for the last 10 years.

The paper goes on to say that over the past decade there has been a  dramatic increase in the understanding of the many biological actions that result from vitamin D acting through its daughter steroid  hormone, 1α,25-dihydroxyvitamin D3 [1α,25(OH)2D3] in collaboration with its cognate vitamin D receptor (VDR). In other words Vitamin D does more than support bone health.
