The B Group Vitamins - also known as 'Vitamin B Complex'.

There are currently six numbered vitamins and two unnumbered vitamins in
this group. The complex of vitamins was discovered in yeast, and were
originally thought to be a single substance. Later, its constituents
were seperated and labelled. Further analysis showed that B's 4, 5, 7,
8, 9, 10 and 11 weren't vitamins, hence only 1, 2, 3, 5, 6, 12 remain,
plus biotin and folacin.
