(Source Naturals) Resveratrol, by Source Naturals, is a protective compound produced by grapevines and other plants. Studies have demonstrated that resveratrol has potent antioxidant activity and also has the ability to inhibit platelet aggregation. These actions may help prevent free radical damage throughout the body and provide support to the cardiovascular system. They may also explain the "French Paradox" -- the low incidence of heart disease among the French people who eat a relatively high-fat diet. Just two tablets twice daily provide that protection.
