A well balanced diet usually supplies the vitamin needs of a healthy person in an adequate quantity. There are 2 types of vitamins – fat soluble vitamins (A,D,E and K) and water soluble vitamins (B group of vitamins and vitamin C) It is necessary to take vitamins in the recommended doses on a daily bases to enhance the overall well being of the body and prevent the development of any deficiency syndromes.

Recommended daily allowance (RDA) is defined as the amount of nutrients sufficient for the maintenance of health in nearly all people. This recommendation is estimated to meet the requirements of almost all healthy people.
