Resveratrol is an antioxidant which may help to protect cells from free radicals. It may help to maintain a healthy cardiovascular system and also normal female hormones. Resveratrol is a compound found primarily in red wine, though in our product it comes from the Japanese Knotweed plant. In comparison an average glass of red wine provides approximately 1mg of resveratrol at best, while a handful of peanuts provide about 73µg of resveratrol. Resveratrol capsules provide 150mg resveratrol each. Micrograms (µg) are 1000 times smaller than milligrams (mg).
