Amino acids BCAA are the building blocks of protein, which contributes to a growth and maintenance of muscle mass. The combination of these essential amino acids (L-Leucine, L-Isoleucine, L-Valine) makes up approx. 33% of total muscle protein.

L-Glutamine is the most abundant amino acid in the body, comprising more than 60% of the free amino acid pool in skeletal muscle and greater than 20% of total circulating amino acids.
