Free Radicals

Oxidative stress occurs when there are insufficient antioxidants in the body to counteract the level of free radical molecules. Free radicals are a natural by-product. They occur when the body turns food into energy. Breathing air is another process that results in an oxygen molecule paired with a free radical. Your body can also produce too many free radicals as a reaction to stress, smoking, excessive drinking of alcohol, and over-exposure to the sun or pollution. Free radicals serve a purpose for our immunity and body functions. However, we only need low levels of free radicals. When there is an over-supply, the body experiences oxidative stress.
