OPC (Oligomeric Proanthocyanidins) Grape Seed Extract is a set of bioflavonoid complexes (polyphenols and flavonoids) that perform as free radical scavengers in the human body. OPCs have many beneficial effects in the body, including stabilizing capillary walls and avoiding increases in capillary permeability. Connective tissue, blood vessels and capillary walls are all supported structurally by a collagen matrix. Grape seed extract supports collagen structures and helps to avoid destruction of collagen, as it promotes the reinforcement of the natural cross-linking of collagen fibers. Grape seed extract is a potent antioxidant and as such provides protection against cellular damage by free radicals.
