People always mention that oxygen is a vital component for living. However, oxygen has a downside to it. It is a highly reactive atom that has high capability to becoming damage-causing atom in our body commonly known as “free-radicals” which has one or more missing electrons in the molecule. The action of antioxidants helps to get rid of free-radicals in our body and it helps to prevent things like metabolism breakdowns or unwanted attacks by donating electrons back to the cell. Once free-radicals attack cells in the human body, it makes the cells vulnerable to damage as free radical attack lipids and membranes through the process called oxidation. Anti-oxidants can also help slow down aging-process in our body.
