Your body uses antioxidants to help protect itself from the damaging effects that can be caused by oxidants.  Oxidants, commonly known as “free radicals” are constantly being produced within the body as your internal systems carry out the normal processes of delivering oxygen to cells.  Free radicals are also produced by stress, unhealthy foods and even exercise.  It is important to provide your immune system with a good supply of antioxidants which become available to help immobilize free radicals before they attack and oxidize molecules in the body.
