Resveratrol is a naturally occurring phytoalexin produced by some higher plants in response to injury or fungal infection. Phytoalexins are chemical substances produced by plants as a defense against infection by pathogenic microorganisms, such as fungi. Alexin is from the Greek, meaning to ward off or to protect. Resveratrol may also have alexin-like activity for humans. Epidemiological, in vitro and animal studies suggest that a high resveretrol intake is associated with a reduced incidence of cardiovascular disease, and a reduced risk for cancer.

What is this product?
Resveratrol is a kind of natural polyphenols with strong biological properties, mainly derived from peanuts, grapes (red wine), knotweed, mulberry and other plants.Resveratrol generally exists in the trans form in nature, which is theoretically more stable than the cis form. The efficacy of resveratrol mainly comes from its trans structure.Resveratrol is in great demand in the market. Because of its low content in plants and high extraction costs, the use of chemical methods to synthesize resveratrol has become the main means of its development
