Many B vitamins are used in the body individually or in combination with enzymes to help release energy from carbohydrates, fat, and protein. Vitamin B coenzymes are crucial to the metabolic pathways that generate the energy needed by every cell in the body. Because they are codependent in their metabolic activities, a deficiency of one B vitamin can affect optimal functioning of organ systems throughout the body.126

Most B-complex products contain the same amount of each B vitamin. But studies have shown that pantothenic acid (vitamin B5) has an ideal daily dose of over 700 mg. Complete B-Complex contains potent, but safe, and scientifically validated amounts of the B vitamins.
