- NOW Sports products are comprehensively tested so you can trust that our products are pure and effective for every level of athletics.
- NON-ESSENTIAL AMINO ACID: 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 by-product of protein metabolism.*
- IMPORTANT MUSCULAR ENERGY SOURCE*: 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.
- GMP Quality Assured: NPA A-rated GMP certification means that every aspect of the NOW manufacturing process has been examined, including our laboratory/testing methods (for stability, potency, and product formulation).
