Encyclopedia > B vitamin

Vitamin B is a complex of several vitamins. The name arises because it was once considered a single vitamin, much like Vitamin C or Vitamin D. Since later research has shown it is in fact a complex of chemically distinct vitamins that happen to often coexist in the same foods, the name has gradually declined in use, being replaced by the generic term "the B vitamins", the vitamin B complex , or by the specific names of each vitamin.


The B vitamins are:

Several other substances which are not human vitamins have been referred to as B vitamins. These include:

  • Vitamin B-4 (Adenine)
  • Vitamin B-7* — more commonly called Vitamin I
  • Vitamin B-8 (Ergadenylic acid)
  • Vitamin B-10, also Vitamin R (Pteroylmonoglutamic acid mixed with other B vitamins)
  • Vitamin B-11, also Vitamin S
  • Vitamin B-13 (Pyrimidinecarboxylic acid or orotic acid, often misspelled erotic acid)
  • Vitamin B-14 — a mixture of B-10 and B-11
  • Vitamin B-15 (Pangamic acid)
  • Vitamin B-16
  • Vitamin B-17 (Amygdalin)
  • Vitamin B-22, often claimed as an ingredient of Aloe vera extracts
  • Vitamin B-c, another name for Vitamin B-9 (Folic acid)
  • Vitamin B-h (Inositol)
  • Vitamin B-t (L-Carnitine)
  • Vitamin B-w, another name for Vitamin B-7 (Biotin)
  • Vitamin B-x, also PABA (Para-Aminobenzoic acid)


In addition to coexisting in the same foods, the B vitamins often work together to bolster metabolism, maintain healthy skin and muscle tone, enhance immune and nervous system function, and promote cell growth and division — including that of the red blood cells that help prevent anemia.


Together they also help combat the symptoms and causes of stress, depression, and cardiovascular disease.


All B vitamins are water soluble, and are dispersed throughout the body and must be replenished daily with any excess excreted in the urine.


Brewer's yeast is a good source of Vitamin B.

As might be expected due to its high content of brewer's yeast, beer is a good source of B vitamins [4], [5], although this may not be true of filtered beers [6], [7]; in fact, beer is sometimes referred to as "liquid bread" [8].
