A vitamin is an organic molecule (or a set of molecules next door to linked chemically, i.e. vitamers) that is an necessary micronutrient which an organism needs in small quantities for the proper practicing of its metabolism. essential nutrients cannot be synthesized in the organism, either at all or not in acceptable quantities, and suitably must be obtained through the diet. Vitamin C can be synthesized by some species but not by others; it is not a vitamin in the first instance but is in the second. The term vitamin does not append the three extra groups of essential nutrients: minerals, critical fatty acids, and vital amino acids. Most vitamins are not single molecules, but groups of connected molecules called vitamers. For example, there are eight vitamers of vitamin E: four tocopherols and four tocotrienols. Some sources list fourteen vitamins, by including choline, but major health organizations list thirteen: vitamin A (as all-trans-retinol, all-trans-retinyl-esters, as well as all-trans-beta-carotene and other provitamin A carotenoids), vitamin B1 (thiamine), vitamin B2 (riboflavin), vitamin B3 (niacin), vitamin B5 (pantothenic acid), vitamin B6 (pyridoxine), vitamin B7 (biotin), vitamin B9 (folic critical or folate), vitamin B12 (cobalamins), vitamin C (ascorbic acid), vitamin D (calciferols), vitamin E (tocopherols and tocotrienols), and vitamin K (phylloquinone and menaquinones).

Vitamins have diverse biochemical functions. Vitamin A acts as a regulator of cell and tissue growth and differentiation. Vitamin D provides a hormone-like function, bendable mineral metabolism for bones and new organs. The B rarefied vitamins play a part as enzyme cofactors (coenzymes) or the precursors for them. Vitamins C and E function as antioxidants. Both deficient and excess intake of a vitamin can potentially cause clinically significant illness, although excess intake of water-soluble vitamins is less likely to realize so.

Before 1935, the unaided source of vitamins was from food. If intake of vitamins was lacking, the upshot was vitamin nonattendance and consequent nonexistence diseases. Then, commercially produced tablets of yeast-extract vitamin B obscure and semi-synthetic vitamin C became available.

This was followed in the 1950s by the increase production and marketing of vitamin supplements, including multivitamins, to prevent vitamin deficiencies in the general population. Governments mandated complement of vitamins to staple foods such as flour or milk, referred to as food fortification, to prevent deficiencies. Recommendations for folic cutting supplementation during pregnancy shortened risk of infant neural tube defects.

The term vitamin is derived from the word vitamine, which was coined in 1912 by Polish biochemist Casimir Funk, who and no-one else a obscure of micronutrients vital to life, every of which he presumed to be amines. later than this presumption was highly developed distinct not to be true, the "e" was dropped from the name. every vitamins were discovered (identified) in the middle of 1913 and 1948.
