Product Information
Resveratrol (3,5,4'-trihydroxy-trans-stilbene) is a natural compound found in red grape skin, Japanese knotweed (polygonum
cuspidatum), peanuts, blueberries and some other berries. It is a powerful antioxidant produced by some plants to protect
them against environmental stresses. Antioxidants neutralize free radicals, which are believed to be the cause of aging.
Japanese knotweed is the plant source with the highest resveratrol content.
