The Body - Vitamins defined

Vitamins are organic chemicals that a given living organism requires in trace quantities for good health, but which the organism cannot synthesize, and therefore must obtain from its diet. The term vitamin does not encompass other essential nutrients such as dietary minerals, essential fatty acids or essential amino acids. Nor is it used for the large number of other nutrients that are merely health-furthering, but not strictly essential. Humans require 13 different vitamins.

The word vitamin was coined by the Polish biochemist Kazimierz Funk in 1912. Vita in Latin is life and the -amin suffix is short for amine; at the time it was thought that all vitamins were amines. Though this is now known to be incorrect, the name has stuck.
