Resveratrol

Resveratrol is a naturally occurring substance in Japanese knotweed (Polygonum cuspidatum). It belongs to polyphenols, a group of organic molecules mainly found in vegetables, fruits, herbs and other plants. Polyphenols consist of different phenolic groups and include substances such as simple phenols, coumarins, flavonoids and anthocyanins. They play a crucial role in the metabolism of plants, protect the plant, regulate growth and provide protection against UV light, oxidation and heat.
Resveratrol has beneficial properties for protecting healthy cells and tissues in the body and is also good for the heart and blood vessels.
