Mega Amino 5050 mg amino acids per serving Contains amino acids from different types of amino acid sourcesWHAT ARE AMINO ACIDS? One of the main components of our cells is protein, and amino acids are the basic building blocks of proteins. We know of 20 different amino acids. There are 9 types of essential amino acids, which are fundamental for the human body, but cannot be produced by it. For this reason, it is important to ensure the optimal amount from external sources. Conditional essential amino acids, such as L-glutamine, L-arginine or L-tyrosine, can be produced by the human body, but under certain conditions, for example during intense and prolonged training, their supplementation can also be useful. In these cases, our body may require more amino acids than it produces. Like all BioTechUSA products, Mega Amino is composed only of safe and carefully selected ingredients. We recommend Biotech USA Mega Amino if you prefer dietary supplements in tablet form.
