Whenever a molecule loses an electron from its shells, it is said to be in an “oxidation state.” We all know that losing an electron makes the molecule unstable or “free radical” which is highly reactive in nature. It has the tendency to combine (or “attack”) with other atom or molecule in its surrounding. This unstable and highly reactive behavior of free radicals can often lead to a chain reaction which can damage healthy cells. As a byproduct of various metabolic processes that are carried inside our body, free radicals are regularly produced. Besides, being by-products of natural digestive processes, the production of free radicals is also attributed to medicines as well as pollutants that we ingest.

Fortunately, our body also produces antioxidants which neutralize the effect of the free radicals. The function of the naturally produced antioxidants in our body is to counterbalance the free radicals that are produced in the various metabolic activities of body cells.
