B complex is comprised of 11 B vitamins, namely, Thiamin, Riboflavin, Niacin, Pantothenic Acid, Biotin, Folic Acid, Cyanocobalamin (B12), Choline, Inositol, and Para-aminobenzoic Acid (PABA). Because the B vitamins work together, a deficiency in one often indicates a deficiency in another.

B Vitamins contribute to many functions in the body for example: energy yielding metabolism, the normal functioning of the nervous system, normal psychological function and mental function, normal hair, vision and skin, normal lipid metabolism, homocysteine metabolism, function of the immune system and the reduction of tiredness and fatigue.
