Providing Rich Antioxidant Activity
Grape Seed Extract is a potent extract from grape seeds, which are rich in flavonoids, specifically oligomeric proanthocyanidins (or OPC's). OPCs are widely distributed in plants, being found in cocoa, chocolate, apples, peanuts, almonds, cranberries, blueberries, and in the bark of pines, among other plants.
OPCs from grape seed are considered strong free radical fighters - 15 to 25 times stronger than Vitamin E. Interestingly, proanthocyanodins are one of only a few antioxidants that cross the blood brain barrier. Promising preliminary research indicates that grape seed extract can by beneficial in improving night vision.
They may help prevent the damage to cells by free radicals and stabilizes collagen and maintains the health of elastin. OPCs are considered beneficial to cardiovascular and circulatory health.
In addition to antioxidant activity, proanthocyanidins from grape seed extract may have anti-inflammatory, anticarcinogenic, and anti-atherogenic activities. Research has shown anti-tumor promoting activity with topic grape seed proanthocyanidins -- both topically for skin cancer and internally for things like breast and lung cancer.
