Product Function
Resveratrol weight loss, Resveratrol is naturally occurring phytoalexin produced by some higher plants in response to injury or fungal in fection. Phytoalexins are chemical substances produced by plants as a defense against in faction by pathogenic microorganisms,Natural Resveratrol may also have alexin-like activity for humans. Epidemiological, in vitro and animal studies suggest that a high resveratrol intake is associated with a reduced incidence of cardiovascular disease, and a reduced risk for cancer.
