About MegaNatural Grape Seed Extract Products
Many have heard reports claiming that red wine, Concord and Rubired grape juice, and high quality grape seed extracts are good for the heart. Phenols and tannins, which are found in red grapes, give these products their reported benefits. The key active phenols are called proanthocyanidins, a class of flavonoid phenols that are antioxidants more potent than vitamin C and E.
A high quality grape seed extract, such as MegaNatural® Gold grape seed extract, is a pure source of these compounds containing over 90 percent procyanidins. Two hundred mg. of grape seed extract will deliver the same level of procyanidins as a four-ounce glass of red wine without the alcohol present in wine. Also, a six-ounce glass of red grape juice will have about 200 mg of procyanidins but also 130 calories and 30 grams of sugar.
Scientists continue to make new discoveries about 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 scientific study conducted at the University of California, Davis, 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.
