Vitamins (combination of two words: Vital Amines) are the complex organic substance essential in small quantities to the metabolism (nutrition) in most animals. These are found in minute quantities in food, in some cases are produced by the body, and are also produced synthetically. The human body needs them to work properly, so that we can grow and develop just like we should. Their deficiency results in many serious disorders.

Vitamins are divided into two major groups: the 'fat-soluble vitamins' designated as vitamin A, vitamin D, vitamin E, and vitamin K, and the 'water-soluble vitamins' which include vitamin C and the group of molecules referred to as the vitamin B complex. Each of them has its own special role in the development of human body.

Vitamin A
Vitamin A, a fat-soluble vitamin, plays a really big part in eyesight and helps us to see in dim light and also at night. Vitamin A is also involved in the formation and maintenance of healthy skin, hair, and mucous membranes. In addition, it is necessary for proper bone growth, tooth development, reproduction and for the development of epithelial cells (that line any opening to the body e.g.; nose, throat, lungs, mouth, stomach, intestines and urinary tract).

Vitamin A can be found in eggs, milk, carrots, spinach, sweet potatoes, fish oil, liver (pork, lamb, chicken, turkey or beef), butter, broccoli, apricots, nectarines, cantaloupe, and orange or yellow vegetables or fruits. The deficiency of vitamin A can cause two major disorders like: night blindness and drying of skin.
