L-ArginineL-OrnithineL-LysineTri-Amino is a comprehensive product that combines three important amino acids into one easy-to-take formula. Arginine and ornithine are essential components of the urea cycle. This detoxifying cycle allows the body to convert ammonia, the toxic byproduct of amino acid breakdown, to urea. Tri-Amino also has lysine, an essential amino acid known for its role in the maintenance of nitrogen balance. Together these amino acids are critical for protein metabolism.
