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", or by the specific names of each vitamin. Vitamin B-1 (Thiamine) Vitamin B-2, also Vitamin G (Riboflavin) Vitamin B-3, also Vitamin P or Vitamin PP (Niacin) Vitamin B-4 (Adenine) Vitamin B-5 (Pantothenic acid) Vitamin B-6 (Pyridoxine) Vitamin B-7, also Vitamin H (Biotin) Vitamin B-7* — more commonly called Vitamin I Vitamin B-8 (Ergadenylic Acid) Vitamin B-9, also Vitamin M (Folic acid) Vitamin B-10, also Vitamin R (Pteroylmonoglutamic acid mixed with other B vitamins) Vitamin B-11, also Vitamin S Vitamin B-12 (Cyanocobalamin) Vitamin B-13 (Pyrimidinecarboxylic 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 (Folic acid) Vitamin B-h (Inositol) Vitamin B-t (L-Carnitine) Vitamin B-w, another name for Vitamin B-7 Vitamin B-x, also PABA (Para-Aminobenzoic acid) Feb 26 04, 6:15 AM

Vitamin F was the designation originally given to essential fatty acids that the body cannot manufacture. They were "de-vitaminized" because they are fatty acids. http://www.innvista.com/health/nutrition/vitamins/bindex.htm [Feb 26 04 7:19 AM] sequoianoir writes: VITAMIN G is an obsolete term once used for riboflavin (as was Vitamin F). VITAMIN H is an obsolete name for biotin. It is also used to denote many of the sub-vitamin B complex such as Bc, BH, Bp, Bw, and Bx. VITAMIN I is a term sometimes used to denote Vitamin Bw and the now obsolete Vitamin B7. It is a possible internal combination of Vitamins A and E. VITAMIN J is also known as Vitamin C2 or Vitamin Bp Feb 26 04, 6:25 AM
