Antioxidants are natural compounds that fight the destructive effects of unstable molecules called free radicals. Antioxidants have been shown to help slow the effects of aging and may help reduce risk of disease. Brightly coloured fruits and vegetables have high antioxidant potential, but there are other nutrients, like vitamin C, vitamin E, and coenzyme Q10 that also provide antioxidant support. A high ORAC value identifies a potent antioxidant food or supplement.
