Other Label Statements
General Statements: All Other Content
Ornithine is a non-essential amino acid that plays a central role in the urea cycle, functioning along with Arginine and Citrulline to rid the body of ammonia, a byproduct of protein metabolism. Because Ornithine is converted into Arginine, it can help to maintain healthy Arginine levels in the body.* Ornithine can also be converted into other amino acids, such as citrulline, proline, and glutamate, as well as creatine, an important muscular energy source.*
