Resveratrol, a natural polyphenolic compound, is produced by a variety of plants, such as grapes, peanuts and some berries, in response to various biotic and abiotic stresses, including stress, injury, UV-radiation and bacterial and fungal infection. Emerging scientific evidence suggests that resveratrol might be a potent anticancer candidate. The antitumor actions are largely attributed to the antioxidant property of resveratrol. It is also available as a dietary supplement. Consult your doctor to determine whether resveratrol supplements are safe for you.
Pharmacological Doses
As of 2011, there have not been many clinical trials and observations to determine the optimal pharmacological doses of resveratrol. The results of several animal studies conducted by the New York Langone Medical Center suggest that daily doses of 500mg of resveratrol might be safe and potent.
Standardized Grape Seed Extract
Resveratrol from grape seeds has been widely studied for its potential chemopreventive and therapeutic effects. Grape seeds are preventive agents against various human diseases associated with free radicals, including diabetes, heart disease and cancer. Grape seed extract is available as a supplement in several forms such as capsules, tablets and liquid extracts. The University of Maryland Medical Center recommends 25mg to 150mg of a standardized grape seed extract per day to protect your body from oxidative damage caused by free radicals.
