Vitamin D Revisited

On Wednesday, November 30, 2010, the Institute of Medicine's Food and Nutrition Board issued a report saying in essence that supplemental vitamin D over 800 IUs was unnecessary and could even be harmful (more on this in a minute).


Should you ignore this report? Yes. And I'll tell you why.

Taking Supplementation Seriously Part III

There is little debate that a balanced diet is the most desirable method for obtaining essential nutrients, but there are cases when the use of supplemental nutrients may be requisite for insuring adequate nutrient intake. When negotiating the vast number of choices in dietary supplements, one criteria for deciding upon a product is whether it contains natural versus synthetic vitamins and minerals.

Vitamin D The New Vitamin Revolution

There is a vitamin revolution brewing, and it is important to the health of young and old alike as researchers respond to what has been called the “vitamin D deficiency epidemic.” More than a dozen scientists at leading universities both in the United States and abroad have minced no words about it: many of us need more vitamin D. (See “Cod liver oil, vitamin A toxicity, frequent respiratory infections, and the vitamin D deficiency epidemic.”)1 The issue of deficiency may be especially true of children, yet it is also applicable to adults. Quite surprisingly as far as vitamin D is concerned, the suggested intakes in recent decades have fallen rather wide of the mark. Not only are the recommendations of 400 IU/day as an adequate intake (100 percent of U.S. Daily Value) and 2,000 IU/day as an upper limit too low, but also recommendations may have been more realistic 70 years ago. As detailed below, in a tale of two vitamins, A and D, scientists initially bet on the wrong one.
