What are Vitamins?

Vitamins are organic chemical substances which are essential for a normal balanced working and growth of our bodies. These are obtained from the food we eat. Vitamins are present in foods in very small quantities as compared to the other substances which are used up by the body. But even small amounts of vitamins play most important role in our body. They take part in the chemical reactions inside the body which convert the food into energy to reach every cell of the body.
