A Popular Supplement May Reverse the Effects of Exercise

Resveratrol, an antioxidant compound found in red grapes and known for many health benefits, appears to negate the effects of exercise, according to the results of a recent double-blind study. Researchers found that after a four-week exercise trial, men who received resveratrol supplementation failed to see improvement in their fitness levels. Meanwhile, those who received a placebo, experienced the benefits typically associated with an exercise program. Research leader Dr. Brendon Gurd comments, “The results we saw suggest that concurrent exercise training and resveratrol supplementation may alter the body’s normal training response induced by low-volume high-intensity interval training. The data set we recorded during this study clearly demonstrates that resveratrol supplementation doesn’t augment training, but may impair the effect it has on the body.”
