    Resveratrol has exciting potential: Animal studies show a life-extending and athletic enhancement effect. Anti-cancer, anti-inflammatory and other activities have been seen in laboratory tests.

    But ConsumerLab.com's Resveratrol Review found that two supplements provided only 27% and 58%, respectively, of their listed amounts of resveratrol. A third product boasted several hundred milligrams of a red wine grape complex but actually contained only two milligrams of resveratrol. Across thirteen products, daily doses ranged from just 1 milligram to as much as 1,000 milligrams of resveratrol. Prices ranged several fold.

    In this Review, you'll get ConsumerLab's test results, quality ratings, and comparisons for fifteen supplements containing resveratrol. You need to subscribe to get all the test results and ConsumerLab.com's valuable recommendations. In this comprehensive report, you'll discover:
