L-Arginine/Ornithine

Arginine and Ornithine combines two essential amino acids into one optimal supplement. Arginine is necessary for urea metabolism, a process that prepares toxic ammonia for safe excretion by the kidneys. Ornithine is synthesized from Arginine and is a precursor of citrulline, proline and glutamic acid. Both of these amino acids are popular with athletes and other active individuals.
