What are antioxidants?

Antioxidants are simply those substances that protect us from the harmful effects of free radicals produced in our body because of metabolic reactions or because of chemical exposure. 

Due to the fact that they destroy free radicals, these are also called free radical scavengers. For example: Vitamin A, C and E.

Free radicals can be produced in our body as a result of exposure to chemicals, pollution and sun. 

These radicals hunt for the electrons to pair with and stabilize themselves. In this process, they damage proteins, DNA and other components of a cell in our body.

They damage skin and promote ageing, spots on the skin etc. 

Ongoing studies claim that free radicals may also have a role in diseases like cancer. Hence, antioxidants are crucial to keep a check on them to control cell damage.


These antioxidants can be produced in the body which are called Endogenous and those antioxidants which we get from our diet are Exogenous antioxidants. 

Endogenous ones are more efficient in cell damage and repair than the exogenous antioxidants.

The present environment with high levels of chemicals has increased the production of free radicals in the body that only the dietary sources of antioxidants are not enough to repair the damage done by free radicals. 

To compensate for the deficiency of antioxidants, supplements are the easiest solution, but antioxidants can damage the body if they are present in large quantities in the body which is why consulting a doctor is important before taking any supplements.
