Grape seed extract is known as a powerful antioxidant that protects the body from premature aging, disease, and decay. Grape seeds contains mainly phenols such as proan-thocyanidins(oligoantioxidant power of proanthocyanidinsis 20 times greater than vitamin E and 50 times greater than vitamin C.)

Extensive research suggests that grape seed extract is beneficial in many areas of health because of its antioxidant effect to bond with collagen, promoting youthful skin, cellhealth, elasticity,and flexibility. Other studies have shown that proanthocyanidins help to protect the body from sun damage,to improve vision, to improve flexibility in joints arteries, and body tissues such as the heart, and to improve blood circula-tion by strengthening capillaries, arteries, and veins. The most abundant phenolic compounds isolated from grape seed arecatechins, epicatechin, procyanidin, and some dimers and trimers.
