Abstract

Vitamins are complex chemical substances, required by the body in very small amounts. Vitamins are organic substances present in small amounts in food; they are required for carrying out vital functions of the body. This chapter covers the classifications of vitamins, fat-soluble vitamins, water-soluble vitamins, and vitamin deficiencies and hypervitaminosis. Vitamins are involved in the utilization of the major nutrients like proteins, fats and carbohydrates. Though, needed in small amounts, they are essential for health and wellbeing of the body. Fat-soluble vitamins are vitamin A, D, E and K. Water-soluble vitamins are the vitamins of the B group and vitamin C. The deficiency of vitamin A is usually manifest clinically as night blindness, xerophthalmia, Bitot’s spots and keratomalacia. Pellagra is caused due to deficiency of niacin.
