B vitamins are cofactors in literally thousands of enzymatic reactions in the body and are especially critical for energy-releasing reactions (glycolysis, Kreb’s cycle reactions, gluconeogenesis and lipolysis). Most physiological processes require multiple B vitamins, hence the wisdom of supplementing B-vitamins as a complex with a balance of all. BComplex also contains choline and inositol, which are non-essential cofactors for efficient fat metabolism and cell membrane function.
