Now L-Arginine & L-Ornithine (Sports) 100 caps

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 among athletes and other active individuals.

As a dietary supplement, take 2 capsules 2 to 3 times daily, preferably with juice or water on an empty stomach, before exercise or at bedtime.
