A vitamin is an organic compound and a vital nutrient that an organism requires in limited amounts.

An organic chemical compound (or related set of compounds) is called a vitamin when the organism cannot synthesize the compound in sufficient quantities, and it must be obtained through the diet; thus, the term vitamin is conditional upon the circumstances and the particular organism.

For example, ascorbic acid (one form of vitamin C) is a vitamin for humans, but not for most other animal organisms.

Supplementation is important for the treatment of certain health problems, but there is little evidence of nutritional benefit when used by otherwise healthy people.

Health is the level of functional and metabolic efficiency of a living organism.

In humans it is the ability of individuals or communities to adapt and self-manage when facing physical, mental or social changes.

The World Health Organization (WHO) defined health in its broader sense in its 1948 constitution as "a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity." This definition has been subject to controversy, in particular as lacking operational value, the ambiguity in developing cohesive health strategies, and because of the problem created by use of the word "complete".

Other definitions have been proposed, among which a recent definition that correlates health and personal satisfaction.

Adenosine monophosphate (AMP), also known as 5'-adenylic acid, is a nucleotide that is used as a monomer in RNA.

It is an ester of phosphoric acid and the nucleoside adenosine, which does not have the typical high energy bond of the so called adenosine monophosphate ("AMP") that arises on the hydrolysis of ATP.

AMP consists of a phosphate group, the sugar ribose, and the nucleobase adenine.

As a substituent it takes the form of the prefix adenylyl-.

The term natural health product (NHP) is used in Canada to describe substances such as vitamins and minerals, herbal medicines, homeopathic preparations, energy drinks, probiotics, and many alternative and traditional medicines.

A recent survey showed that 73% of Canadians consume NHP on a regular basis.

NHP are obtainable without a prescription and are required to be safe to be used as an over-the-counter product.
