Grape seeds(Vinis vinifera) are an excellent source of oligomeric proanthocyanidins (OPCs) and have been the subject of clinical research in France for their antioxidant activity. Antioxidants play an important role in the development of collagen including skin, connective tissue and vascular walls.* Nature's Way Standardized Grape Seed Extract is a high potency (955) polyphenol extract.

grape seed extract is rich in flavonoids, phytochemicals that have antioxidant properties some consider even greater than the old standbys 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.

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.

An alternative source for PCOs is Pycnogenol (pik-NODGE-en-all), the brand name for a PCO derived from the bark of the maritime pine. Experts compare its health benefits to those of grape seed extract, and in fact many research studies examining the therapeutic effects of PCOs have relied on the use of Pycnogenol. It's more expensive than grape seed extract, however.
