A high quality grape seed extract reportedly is a pure source of phenols and tannins. Research continues to reveal the health benefits of these compounds. For example, damage to blood fat (the “bad” LDL cholesterol) due to oxidation may lead to cardiovascular disease, including hardening of the arteries. A study conducted at the University of California, Davis, reportedly concluded that the phenols’ potent antioxidant properties help protect against LDL oxidation, keeping arterial linings healthy. Additional studies lend credence to phenols’ ability to improve circulation, and decrease the fragility of veins and capillary walls.
