Vitamins are organic compounds that are essential for the proper development and well being of every living organism. They belong in those components that should be received through nutrition, since they cannot be composed by the human organism. Their presence in foods can be of natural origin or as a result of a technical enrichment. Vitamins are dististinquished in two basic categories, water soluble (B complex and C) and fat soluble (A,D,E,K).
The EU Regulation 1925/2006 determines the criteria for the fortification of foods with vitamins.
