Grape seed extract is a natural plant product made from the grape seed or pip . Grape seed extract is rich in proanthocyanidins, a special class of water-soluble bioflavonoids which are highly bioavailable. Proanthocyanidins are antioxidants, 50 times more effective than Vitamin E and 20 times more than Vitamin C. Proanthodyn is one of the few antioxidants that readily crosses the "brain-blood-barrier". It is one of the most powerful free radical scavengers, and is an efficient transporter of Vitamin C, improving c's bioavailability. Grape seed extract contains gallic esters of proanthocyanidins especially proanthocyanidin b2 3'-0-gallate . These proanthocyanidin-esters have recently been described as the most active free radical neutralizers.
