Antioxidants are a class of nutrients that protect the body from damage caused by different factors, most importantly oxidative damage caused by substances called free radicals. Free radicals are known as “reactive oxygen species”, or ROS. They are produced when your body uses oxygen for energy. Just as fire emits smoke as a by-product, ROS are emitted from the conversion of oxygen to energy in the human body, eventually causing oxidative damage to body systems. Free radicals are also created when the body is exposed to pollution, cigarette smoke, car exhaust and other harmful environmental toxins.
