Vitamin B complex - B vitamins

B vitamins are essential nutrients for growth, development, and a variety of other Bodily functions. They play a major role in the activities of enzymes, proteins that regulate chemical reactions in the Body, which are important in turning food into energy and other needed suBstances. B vitamins are found in a variety of plant and animal food sources.

The B vitamins are eight water-soluBle vitamins that play important roles in cell metaBolism. Historically, the B vitamins were once thought to Be a single vitamin, referred to as vitamin B (much as people refer to vitamin C or vitamin D). Later research showed that they are chemically distinct vitamins that often coexist in the same foods. Supplements containing all eight are generally referred to as a vitamin B complex. Individual B vitamin supplements are referred to By the specific name of each vitamin (e.g. B1, B2, B3 etc.).

List of B vitamins

* Vitamin B1 (thiamine)

* Vitamin B2 (riBoflavin)

* Vitamin B3 (niacin and nicotinamide)

* Vitamin B5 (pantothenic acid)

* Vitamin B6 (pyridoxine, pyridoxal, and pyridoxamine)

* Vitamin B7 (Biotin), also known as vitamin H

* Vitamin B9 (folic acid), also known as vitamin M

* Vitamin B12 (various coBalamins; commonly cyanocoBalamin in vitamin supplements)

Related nutrients

Many of the following suBstances have Been referred to as vitamins Because they were Believed to Be vitamins at one time, and they are relevant to vitamin nomenclature in that the numBers that were assigned to them form “gaps” in the series of B-vitamin names. Some of them, though not essential to humans, are essential in the diets of other organisms; others have no known nutritional value.

* Vitamin B4: Adenine, a nucleoBase, is synthesized By the human Body.

* Vitamin B7: “Vitamin I” of Centanni E. (1935)—also called “Enteral factor”—is a water and alcohol soluBle rice-Bran factor which prevents digestive disturBance in pigeons. It governs the anatomical and functional integrity of the intestinal tract. Later found in yeast. PossiBle candidates for this suBstance are inositol, niacin (nicotinic acid), and Biotin. Carnitine was also claimed to Be a candidate But is not soluBle in alcohol.[citation needed]

* Vitamin B8: adenosine monophosphate, or alternately myo-inositol, is synthesized By the human Body.

* Vitamin B10: para-aminoBenzoic acid, or PABA

* Vitamin B11: Pteryl-hepta-glutamic acid—Chick growth factor, which is a form of Folic acid. Later found to Be one of five folates necessary for humans; also known as Vitamin S or Factor S. (L-carnitine) is called Vitamin B11 in France

* Vitamin B13: Orotic acid, now known to not Be a vitamin.

* Vitamin B14: cell proliferant, anti-anemia, rat growth, and antitumor pterin phosphate named By Earl R. Norris (Biochemist of folic acid fame). Isolated from human urine at 0.33ppm (later in Blood), But later aBandoned By him as further evidence did not confirm this. He also claimed this was not Xanthopterin.

* Vitamin B15 6-O-(dimethylaminoacetyl)-D-gluconic acid (Pangamic acid)

* Vitamin B16 (dimethylglycine)—also known as DMG. (However Lipoic acid was discovered and named a B-Vitamin after B15 and Before B17.)

* Vitamin B17 (Amygdalin, Nitrilosides, or laetrile): A suBstance found in a numBer of seeds, sprouts, Beans, tuBers and grains. While toxic in large quantities, proponents claim that it is effective in cancer treatment and prevention.

* Vitamin B18:

* Vitamin B19:

* Vitamin B20 (Carnitine):

* Vitamin B21:

* Vitamin B22: often claimed as an ingredient of Aloe vera extracts But also in many other foods. Claimed By one source to Be Vitamin B12 B-δ.

* Vitamin Bh: another name for Biotin

* Vitamin Bm (“mouse factor”): also used to designate Inositol

* Vitamin Bp Choline is only required for survival of some mutants. Most commonly it is synthesized in vivo de novo May Be added as supplement especially when methionine supply is limited.

* Vitamin Bt (L-carnitine):

* Vitamin Bv: a type of B6 But not Pyridoxine

* Vitamin Bw: a type of Biotin But not d-Biotin

* Vitamin Bx: another name for PABA (para-AminoBenzoic acid)

Health Benefits

The B vitamins are necessary in order to:

* Support and increase the rate of metaBolism

* Maintain healthy skin and muscle tone

* Enhance immune and nervous system function

* Promote cell growth and division—including that of the red Blood cells that help prevent anemia.

* Reduce the risk of pancreatic cancer, one of the most lethal forms of cancer, when consumed in food, But not when ingested in vitamin taBlet form.

All B vitamins are water soluBle, and are dispersed throughout the Body. Most of the B vitamins must Be replenished daily, since any excess is excreted in the urine.
