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.
Most of the knowledge of vitamins was obtained during the present century. They are important part of the research and studies relating to the science of nutrition. A deficiency of any particular vitamin can cause serious health problems in our body. There are many different kinds of vitamins and they are given names, like vitamin A, B, C, D, E, etc. Every vitamin has a special value in the body.
For example, vitamin A is important for healthy eyes and skin. Vitamin B is a group of many vitamins which are called B1, B2, etc. and they are essential for the good health of your skin, blood, digestive tract etc. Similarly, all other vitamins are important to keep you healthy and energetic.
