BCAA Powder combines branched-chain amino acids (BCAAs - leucine, isoleucine, and valine) with the amino acid L-glutamine in a delicious orange-flavored powder. BCAAs represent 35% of the essential amino acids found in muscle protein and approximately 40% of the total amino acids required by mammals. BCAAs are unique in that they are a direct source of energy for skeletal muscle, while also serving as intermediates for ATP production in the citric acid (Krebs) cycle. They stimulate protein building in muscles, reduce muscle breakdown during exercise, and regulate protein metabolism throughout the body. BCAAs stimulate lean muscle synthesis even in the absence of resistance training, making them an effective raw material for maintaining lean muscle mass in athletes as well as in populations unable to exercise but at risk of muscle loss. This product is free from sucrose, fructose, and artificial sweeteners, and is naturally sweetened with the stevia plant.
