Biological oxidation is the gradual aging process of the body. Oxidation basically occurs all over the body and at a cellular level. There is an oxidation reaction theory that states that oxygen reacts within the body and produces by-products called free radicals. A free radical is an oxygen molecule that has lost an electron. Since it is now in an unstable state it tries to steal an electron from another molecule. By doing so the radical may cause damage or even destroy the surrounding cells. Free radicals are thought to be a cause of cancer.

Over time, these radicals build up and aging occurs.
