Vitamin
Name:
Vitamin
Detailed information:
Any of a number of complex organic compounds, present in natural products or made synthetically, which are essential in small proportions in the diet of animals and humans. Some are fat soluble(A, D, K); others are water soluble (B complex, C). Their precursors are called provitamins. A normal diet usually contains sufficient vitamins for health, although older people, the ill, young, or infirm may require different standards. Their usual use in medicine is restricted to correction of specific metabolic deficiencies. Some authorities believe that habitual intake of standard vitamin preparations readily available on the market is of little if any nutritional benefit.
