What is a Vitamin?
In 1912, Polish biochemist Casimir Funk coined the word vitamine. He had isolated a complex of micronutrients essential to life, and concluded incorrectly, that they were all amines. As a result, the”e” was dropped from the name, and vitamines became vitamins.
All vitamins essential for human well being were identified between 1913 and 1948
A vitamin is an essential micronutrient needed in small quantities for the proper functioning of the metabolism.
An essential nutrient cannot be synthesised (or produced) in the body of a living organism, either at all or in the necessary minimum amount required for good health. A deficiency of a specific vitamin will manifest in related deficiency symptoms – eg scurvy is caused by a deficiency of vitamin C.

At the same time, how much is too much?
