BCAA Complex contains the ideal 2:1:1 ratio of the free-form, crystalline branched chain amino acids L-Leucine, L-Isoleucine and L-Valine combined with the conditionally essential amino acid L-Glutamine. The higher amount of Leucine reflects it’s importance in muscle metabolism as the most effective branch chain amino acid for stimulation of protein synthesis and it is more readily utilized for energy. BCAAs exert an anticatabolic effect by reducing the breakdown of protein, thereby protecting muscle tissue. Glutamine is a preferred source of fuel for the intestinal cells and is in high demand by skeletal muscles following physical exertion. Vitamin B6 enhances amino acid metabolism.
