The B vitamins consist of a large number of substances involved in the metabolism of all living cells. They play the role of coenzyme, they work with proteins in the multiple enzymatic systems of our body. The functions of B vitamins are closely synergistic and, because of these interrelationships, a deficit in one or more of them can lead to the deficiency of the others and slow down their use. B vitamins are water soluble and are not stored by the body. They must be replaced daily and the surplus eliminated.
