Resveratrol Falls Short In Health Benefits

Posted Oct 25 2012 9:50pm

Resveratrol, an ingredient in red wine thought to improve insulin sensitivity, reduce risk of heart disease and increase longevity, does not appear to offer these benefits in healthy women, new research at Washington University School of Medicine in St. Louis indicates.

The study, reported online Oct. 25 in Cell Metabolism, involved 29 post-menopausal women who did not have type 2 diabetes and who were reasonably healthy. For 12 weeks, half took an over-the-counter resveratrol supplement, and the rest got a placebo, or sugar pill.

“Resveratrol supplements have become popular because studies in cell systems and rodents show that resveratrol can improve metabolic function and prevent or reverse certain health problems like diabetes, heart disease and even cancer,” says senior investigator Samuel Klein, MD, director of Washington University’s Center for Human Nutrition. “But our data demonstrate that resveratrol supplementation does not have metabolic benefits in relatively healthy, middle-aged women.”
