Vitamins
Vitamins (combination of two words: Vital Amines) are the complex organic substance important in tiny quantities to the metabolism (nutrition) in most animals. These are found in minute quantities in food, in hardly any cases are produced by the body, and are also produced synthetically. The human body needs them to output completely, so that we can grow and develop just like we should. Their deficiency results in many serious disorders.
Vitamins are split into two major groups: the ?at-soluble vitamins?assigned as vitamin A, vitamin D, vitamin E, and vitamin K, and the ?ater-soluble vitamins?which include vitamin C and the group of molecules referred to as the vitamin B complex. Every one of them has its own special role in the development of human body.

Vitamin A is also involved in the establishment and maintenance of healthy skin, hair, and mucous membranes. In addition, it is crucial 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).
