In addition to the 3 branched-chain amino acids (leucine, isoleucine, and valine), which have an important role in reducing muscle damage, there is also glutamine, another amino acid that helps prevent muscle catabolism while protecting immune and intestinal health. If this combination of 4 amino acids were not enough, this product has double the amount of leucine (4:1:1), and this amino acid plays a key role in muscle mass gain. Since the amino acids are in isolated form, they are the best option to take during training, as they do not require extensive digestion and can even be taken during the most intense workouts.
