With our modern lifestyle, it is hard to avoid free radial damage and to get the protection we need to neutralize unstable or radical oxygen molecules that attack our cells. Free radials, or oxidants, result when your body is exposed to air pollution, stress, chemicals, radiation, and cigarette smoke. Unfortunately, these free radicals can build up and over time can damage cells and tissues. This can cause a variety of health problems and premature aging. By keeping these oxidants under control, the human body is better able to fight diseases and to recover from injuries.
