Anti-oxidants are, as the name indicates, chemical compounds that prevent oxidation within the body. Oxidants are free radicals found in both the environment we live in but also in our bodies naturally. The body creates them to help fight off various viruses and microbes, but if there are too many of them, they can cause damage and even contribute to certain diseases. Things like tobacco smoke, polluted air and alcohol can also hit the body with free radicals during our everyday lives. Antioxidants occur naturally in fruits, vegetables etc. The most common ones would be those such as vitamin C and E, and beta-carotene, and these help fight off the cell-damaging free radicals and thus minimize their negative effects on the body and immune system. Free radicals are chemically unstabile molecules that try to bind to other chemical compounds and oxidize (destroy) them. With the right dietary supplements, you can help your body fight off the free radicals and maintain a good health and longevity.
