NOW L-Ornithine 500 mg is a fitness-focused amino acid supplement designed to support healthy protein metabolism and normal urea-cycle function. Each vegetable capsule provides 500 mg of L-ornithine derived from L-ornithine hydrochloride. A complete three-capsule serving supplies 1,500 mg.

Ornithine is a non-essential amino acid that works alongside arginine and citrulline within the urea cycle. This natural process helps the body manage ammonia produced during normal protein metabolism. Ornithine also contributes to pathways associated with healthy arginine levels and the formation of other amino acids, including citrulline, proline, and glutamate. These roles make it a practical option for active adults and fitness-focused users seeking targeted amino acid support.

Each bottle contains 120 vegetable capsules, providing 40 servings. The formula is vegan, vegetarian, non-GMO, kosher, dairy-free, egg-free, soy-free, nut-free, and made without gluten. Intertek GMP certification and accredited laboratory testing provide additional quality assurance. The straightforward capsule format is suitable for adults seeking a routine-friendly L-ornithine supplement without powders, flavors, or complicated preparation.
