This product contains antioxidant compounds, such as resveratrol ans quercetin. After using it for a month I think that it improved my cognitive functions. It is supposed to have same effects on longevity as calorie restriction. I guess you have to use it for a long time to reap those benefits. Another similarly good product is by Thorne Research : PolyResveratrol-SR. Click on my username for more reviews!
