Vitamin B Complex
The B-group vitamins are several different substances closely cooperating in the body's metabolic processes. Although some of the functions of many of them overlap, each vitamin has its own action profile and cannot replace another. Their effectiveness is greater when they are administered together, and each ingredient is in equilibrium with the other vitamins of this group. Deficiency or excess of any of B vitamins adversely affects the activity of others. B vitamins are: vitamin B1 (thiamine), vitamin B2 (riboflavin), vitamin B3 (niacin, nicotinamide), vitamin B4 (choline), vitamin B5 (pantothenic acid), vitamin B6 (pyridoxine), vitamin B8 (inositol) , vitamin B9 (folic acid), vitamin B12 (cyanocobalamin).
