Antioxidants are substances that helps in preventing cell damage and repairing injuries to body cells. Our body naturally produces free radicals, which are highly reactive chemicals.  Presence of abundant quantity of free radicals is not good for our health.

These free radicals react with different cells causing physical damage to the cell components and structures including DNA, proteins & cell membranes and affecting the normal functioning of the cells by impairing or inactivating parts of cells. At the larger level, these constant damages to cells may result in developing heart disease, stroke, diabetes, ageing, cancer and many more serious illnesses.

Antioxidants largely protect our cells from these damages.

Antioxidants are substances that prevent these free radicals to react with body cell parts and thus avoid damage to them. The antioxidants neutralizes these free radicals by safely reacting with them and blocking the chain reaction that results in long-term damage to the cells. Additionally, antioxidants promote self-healing mechanism of the body to repair the damages happened to the cell parts.
