2011 March 10 by Randall Neustaedter OMD A new study published
in the Feb 2011 issue of the Anticancer Research journal
confirms that Vitamin D in the range of 4000-8000 IU is
necessary for adults to maintain an adequate blood level of
vitamin D to prevent chronic disease, including diabetes and
cancer. This level of supplement intake contradicts the recent
recommendation of the US Institute of Medicine, which would
limit intake to much lower levels. That recommendation proved
very controversial and many vitamin D experts complained that
their advice was spurned by the recommendation committee. This
study from the University of California, San Diego School of
Medicine and Creighton University School of Medicine in Omaha
shows the wisdom of the Vitamin D Council’s recommendation that
adults take 5,000 IU of vitamin D3 per day. My recommendation is
that adults continue to take 5,000 IU Vitamin D3, children 2,000
IU, and infants 35 IU per pound of body weight (or 400-1,000 IU
depending on weight).
