Antioxidants are an important component of good nutrition and a healthy diet.  Antioxidants help reduct the effects of oxidative stress and free radicals.

Red grape skin is rich in polyphenol antioxidants, including anthocyanins (which give red grapes colour) and Resveratrol, a potent antioxidant.

Resveratrol has poor bioavailability in the body, due to its rapid metabolism.  This reduces its potency.  Bio activated Resveratrol contains a black pepper extract that is rich in piperine, a substance which inhibits the enzymes that break down resveratrol in the body, increasing its bioavailability and potency over 1000%.
