Supplements of red wine antioxidant don’t help obese men

A small trial at Aarhus University Hospital in Denmark found supplements of resveratrol, an antioxidant found aplenty in red wine, did not improve insulin sensitivity or heart health in obese men.

Despite showing early promise in some animal studies, researchers found no difference in insulin sensitivity in 24 obese but otherwise healthy men who took daily 1,500-milligram doses of resveratrol compared to other men who took an inactive placebo for four weeks.
