What Are Antioxidants? Simple Definition of How They Work

An antioxidant works by giving a free radical an electron. This neutralizes it, meaning it longer needs to steal electrons from cells. In order for antioxidants to work, the free radicals need to encounter them before the body’s cells. This is why more antioxidants are believed to be better, because they increase the likelihood of that happening.
