Resveratrol, like soybean isoflavone in soybean, is a phytochemical component contained in some natural plants. Resveratrol in the market is extracted from Polygonum cuspidatum. At present, resveratrol is exported at home, which means that there are many products produced by resveratrol abroad. At present, at least a dozen companies in China produce resveratrol, and Guanzhong Jianye Bio is a professional company.

Of course, there are different opinions about the efficacy of resveratrol. At present, the mainstream view is still: anti-cancer, anti-aging and prevention of flatulence.
