Vitamins (en: vitamin) are organic compounds in limited quantities as vital nutrients that are required by our organs. An organic chemical compound (or a related set of compounds) is defined as a vitamin when it cannot be synthesized in sufficient quantities by the organism and therefore must be obtained by the diet. Such a compound of vitamins depends on the circumstances of the organism. The term vitamin does not include many other essential nutrients such as dietary minerals, essential fatty acids, or essential amino acids, and many other nutrients that promote health. Today there are thirteen vitamins recognized internationally.
Vitamins are classified by their biological and chemical activity, not by their structure, and have diverse bio-chemical functions. Some act as modulators of the metabolism and of the organs (e.g. Vitamin), or regulate of cell growth and tissue (e.g. some forms of vitamin A). A wide variety of vitamins (e.g. B complex vitamins), function as precursors for enzymes that help the metabolism. In this role vitamins are connected cumulatively: for example biotin is part of the enzymes involved in the production of fatty acids. Vitamins may also be connected as co-enzymes detach molecules that function to carry chemical groups or electrons between molecules. Although these roles in assisting enzyme-substrate are the known functions of vitamins this does not mean that the remaining functions are equally important.
By the mid 1930’s vitamins were taken solely through food intake and changes in diet. However, vitamins are produced mostly by commodity chemicals and made widely available as inexpensive semi-synthetic dietary supplements and multi-vitamins.
In reference to the functions of vitamins, we mention the functions of vitamin C, also known as ascorbic acid, a water-soluble nutrient found in foods. (Vitamin C from Superfoods)
Beneficial effects of vitamin B complex (Vitamin B Complex by Superfoods) are: enhanced memory, energy, hair growth, psychological, metabolism, anemia, and cellular functions.
