L-Arginine L-Ornithine L-Lysine Tri-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.* Natural color variation may occur in this product.
