NPA says JAMA vitamin E study shows need for more research

The Natural Products Association's Vice President of Scientific and Regulatory Affairs Cara Welch, Ph.D., calls for more research into the link between vitamin E and prostate cancer.

A statement from Natural Products Association (NPA) Vice President of Scientific and Regulatory Affairs Cara Welch, Ph.D., about a report on vitamin E and prostate cancer in the Journal of the American Medical Association:

"This is one of several studies demonstrating the effects of vitamin E, many of which are positive. Even the authors mention the reported benefit of vitamin E with Alzheimer’s disease and age-related macular degeneration.

This particular study does reveal the need for additional research into the link of vitamin E and prostate cancer, specifically clarifying the mechanism of action, before anyone can draw conclusions. I look forward to seeing additional research in order to accurately evaluate the effect of vitamin E supplementation on prostate cancer incidence.

What is important to remember is that the results of this study, specifically looking at vitamin E in isolation, cannot be extended to taking vitamin E in a combination supplement as the authors imply. In fact, the authors want to extend their initial findings onto supplementation as a whole, urging skepticism from consumers for these products, which they falsely claim are unregulated. This goes beyond the scope of the study and exhibits an unprofessional attitude.

I do not believe this study should affect the use of vitamin E supplementation for certain groups, especially those under the care of a physician. The Natural Products Association has long advocated that consumers use dietary supplements as part of a healthy lifestyle.”
