What is grape seed extract?
Grape seed extract is a naturally occurring plant substance that contains a concentrated source of antioxidant nutrients known as oligomeric proanthocyanidins. These antioxidants can help protect against the effects of internal and external stresses. Scientists have demonstrated that oligomeric proanthocyanidins, more commonly known as OPCs, are more powerful antioxidants than vitamins C, E and beta-carotene.
