Product Description:

Resveratrol is a polyphenolic compound widely found in plants. In 1940, Japanese first discovered resveratrol in roots of plant veratrum album. In the 1970s, resveratrol was first discovered in grape skins. Resveratrol exists in plants in trans and cis free forms; both forms have antioxidant biological activity. The trans isomer has a higher biological activity than cis. Resveratrol is not only found in grape skin, but also in other plants such as polygonum cuspidatum, peanuts, and mulberry.
