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.
Cardiovascular – Resveratrol decreases the viscosity of the blood and acts as anticoagulant to thin blood, effective in treating cardiovascular disease by reducing thrombosis and embolisms that can block arteries and lead to myocardial and cerebral infarctions.
Cancer – Resveratrol has been found to reduce tumor volume, tumor weight Weight Loss – resveratrol is the most potent natural compound mimicking the positive effect of calorie restriction.
