Proanthocyanidins, also called OPCs are a class of nutrients belonging to the bioflavonoid family. Studies have shown that OPCs may prevent cardiovascular disease by counteracting the effects of high cholesterol on the heart and blood vessels. The discovery of the proanthocyanidins opened up a whole new vista in the nutritional industry. Suddenly we began seeking out the natural sources of these highly beneficial nutrient concentrates and found one of the very best sources was grape seeds. You can count on our Grape Seed Extract to be the highest quality and highest concentration possible.
