Resveratrol supplements have been popular since 2006, when studies in animals showed "life-extending" and "endurance-enhancing" effects, among other potential benefits. Although such dramatic effects have not been demonstrated in people, other potential uses are being explored relating to age-related macular degeneration, cardiovascular health, diabetes, and memory. Tens of millions of dollars-worth of resveratrol-containing supplements are purchased in the U.S. each year, and the cost of a 100 mg serving ranges from less than 10 cents to more than $1.50.
