Grape seed extract contains a special class of water-soluble bioflavonoids known as proanthocyanidins. Studies have shown the antioxidant activity of these specific bioflavonoids is 20 to 50 times greater than Beta-Carotene or Vitamins C and E at scavenging specific free radicals. By nourishing blood vessel walls and performing other renewing functions, grape seed extract helps promote healthy blood pressure levels, heart health, and a proper inflammation response.

Grape seed extract is derived from the small seeds (and occasionally the skins) of red grapes. Used extensively in Europe, grape seed extract is rich in flavonoids, phytochemicals that have antioxidant properties some consider even greater than vitamin C and vitamin E. Antioxidants are believed to prevent and control numerous ailments by safeguarding cells against the ravages of unstable oxygen molecules called free radicals. Grape seed has also been used as a dietary source of essential fatty acids and tocopherols and as an antioxidant.

The most valuable flavonoids in grape seed extract are procyanidolic oligomers (also known as proanthocyanidins), commonly called PCOs. Beyond their antioxidant powers, PCOs are thought to improve blood circulation and help strengthen blood vessels. These actions benefit people with heart disease and cancer.

Studies have shown that PCOs in grape seed extract are as much as 50 times more potent than those in Vitamin E and up to 20 times more potent than PCOs in Vitamin C.
