indexSeveral studies have lauded the anti-aging effects of resveratrol, an antioxidant found in grape-based products like red wine. A new study, however, suggests the compound could have some drawbacks.

Recent research has shown that consuming a large quantity of resveratrol in supplement form — about the equivalent of 700 bottles of red wine — may improve balance in elderly mice. A September 2012 study in Circulation Research showed that drinking non-alcoholic, resveratrol-rich red wine for four weeks may lower blood pressure.

One 2011 study even referred to red wine as “exercise in a bottle,” after reservatrol protected against muscle loss in sedentary rats.

However, a new study of older men suggests that reservatrol may block the health benefits gained from exercise.

“We were surprised to find that resveratrol supplementation in aged men blunts the positive effects of exercise training on cardiovascular health…in part because our results contradict findings in animal studies,” lead researcher Ylva Hellsten, a professor with the University of Copenhagen in Denmark, said to the Free Press Journal.

Researchers looked at 27 healthy men aged 65 or older who were physically inactive. They were put through an intensive eight-week regimen which including CrossFit and circuit training exercises.

The men were randomized to receive either 250 milligrams of a resveratrol supplement or a placebo.
