The main active ingredients is trans-resveratrol (3,5,4'-trihydroxy-trans-stilbene), which is a natural anti-oxidant compound. 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. Giant knotweed is the plant source with the highest resveratrol content.
