Ornithine is an amino acid that plays a role in the urea cycle.
Nonessential amino acid but may be essential for individuals with certain diseases or nutritional concerns. Manufactured from arginine and functions similarly to arginine, it stimulates the human growth hormone and is made by the digestion of proteins and some compounds made from arginine. ...
