Antioxidants work in a variety of ways to reduce the effects of free radicals. They can greatly decrease the damage caused by free radicals, stop them from forming to begin with, or "oxidize" them by combining with them and neutralizing their harmful effects through stabilization. The body produces two enzymes on its own to stabilize free radicals. They are Superoxide dismutase (SOD), catalase, and glutathione peroxidase. Although supplements of these enzymes are available directly, the body may not be able to absorb them. Therefore, it is much more useful to supply the body with the building blocks of these enzymes so that the body can build them itself. There are many vitamins, minerals, enzymes, and herbs that act as antioxidants or aid in the production of them such as vitamin E, beta-carotene, vitamins B2, B3, and B6, CoEnzyme Q-10, bilberry, grape seed, pine bark, ginkgo biloba, selenium, zinc, copper, and many others. The best way to make sure your covering all the bases in the neutralization of free radicals is to supplement with a wide variety of antioxidants. Many supplements have been developed containing a blend of antioxidants.
