The Natural Products Association (NPA) is the leading representative of the dietary supplement industry with more than 2,000 members, including suppliers and retailers of vitamins and other dietary supplements. Dr. Cara Welch, senior vice president of scientific and regulatory affairs, comments on review findings that say vitamin D for osteoporosis prevention is inappropriate:
“It’s common knowledge that the beneficial effect of vitamin D in osteoporosis prevention occurs when the supplementation is vitamin D plus calcium. This meta-analysis misleads consumers by only looking at half the equation.
“The beneficial effect of vitamin D and calcium is due to the fact they work in tandem, and examining the outcomes of just vitamin D caused the researchers to start with a weak premise. In fact, the Food and Drug Administration has an approved health claim for vitamin D and calcium regarding osteoporosis.
“This review does not do an adequate job of giving the public the whole story, and it draws a conclusion that should not discourage consumers from taking vitamin D. A deficiency in vitamin D is not uncommon and can be difficult to overcome with diet alone. NPA believes that dietary supplementation is both safe and effective for those who fall under this category. The Institute of Medicine’s recommended dietary allowances are 600 to 800 IU/day for adults over 50 years of age.
"NPA recommends that consumers discuss their dietary supplement regimen with their health care professional.”
