Free Form Amino Acids with Glutamine and B6 Supports Muscle Growth and Post-Workout Recovery Suitable for Vegetarians/Vegans Veggie Caps Dietary Supplement 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. BCAAs exert an anticatabolic effect by reducing the breakdown of protein (thereby protecting muscle tissue) and promoting muscle growth as well as recovery after workouts. Glutamine is a preferred source of fuel for the intestinal cells and is in high demand by skeletal muscles following physical exertion. Vitamin B6 is essential for amino acid metabolism.
