Grape Seed Extract is derived from the small seeds (and occasionally the skins) of red grapes- the same kind that are pressed to make wine. Grape Seed Extract is rich in flavonoids, phytochemicals that have antioxidant properties some consider even greater that the old standbys vitamin C and vitamin E. Antioxidants are believed to prevent and control numerous ailments by safe guarding cells against the ravages of unstable oxygen molecules called free radicals.

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. The antioxidants in grape seed extract can potentially protect the blood vessels from becoming damaged, which may prevent high blood pressure.

Grape seed extract is an industrial derivative of grape seeds, extremely rich in antioxidants and oligomeric proanthocyanidin complexes (OPCs). The extract has been linked to a wide range of possible therapeutic properties including healing wounds and treating conditions such as high cholesterol, atherosclerosis, macular degeneration, poor circulation, nerve damage, as well as preventing cancer.

Grape seed extract can heal dermal wounds. Including grape seed extract in your diet with calcium has a "beneficial effect on bone formation and bone strength for the treatment of bone debility caused by a low level of calcium," improving bone strength. Taking grape seed extract can help reduce the swelling that occurs after an injury or surgery.
