How It Works
How It Works
L-arginine supports urea metabolism, helping your body process ammonia for safe elimination through the kidneys. Ornithine, synthesized from arginine, acts as a precursor to citrulline, proline and glutamic acid. Together, these amino acids support the body's natural processes during periods of increased physical demand.
Who It's For

Who It's Not For
