Prof Ian Reid, lead study author, from the University of Auckland, said the findings [of a new meta-analysis of all vitamin D studies to date] showed that healthy adults did not need to take vitamin D supplements.
“Our data suggest that the targeting of low-dose vitamin D supplements only to individuals who are likely to be deficient could free up substantial resources that could be better used elsewhere in healthcare.”
This study of studies relies on data from “inception to July 8, 2012… of vitamin D (D3 or D2, but not vitamin D metabolites) on bone mineral density.” The major problem with that is historical low-dose trials, mostly with D2. It also talks nothing of other diseases and the various barriers most people having in making vitamin D.
This media blow to vitamin D activism is an indirect victory to Big Pharma.
