The vitamin B supplement you take is a mixture of nutrients that, although they share the same vitamin letter, are in fact distinctly different chemical entities. The reason that they share the same reference letter of the alphabet is that they are all essential water soluble vitamins (Vitamin C being the only other), they frequently work in synergy with apiece other and they often come from common sources and have similar properties in the body. They were therefore at one time believed to be just the one chemical entity.
