Vitamin B complex contains all the vitamins in the B group. The functions of these vitamins appear to be closely interrelated and interdependent. This suggests that the body functions best when the entire complex of vitamins is present. There are many B-complex supplements available on the market, all containing varying amounts of the common B vitamins. Some also contain vitamin C and bioflavonoids. These are often referred to as B complex with C.
The B complex includes thiamin (B-1), riboflavin (B-2), niacin (B-3), pantothenic acid (B-5), pyridoxine (B-6), folic acid (B-9) and cobalamin (B-12). In addition, biotin (vitamin H), choline, inositol and para-aminobenzoic acid (PABA) are often included as part of the B complex.
