NOW Foods L-Ornithine 500mg 120 Veg Capsules

NOW® L-Ornithine supplies 500 mg of free-form L-ornithine in each vegetarian capsule. Ornithine is a non-essential amino acid that plays a central part in the urea cycle — the body's system for converting the ammonia produced by protein metabolism into urea for elimination. Because it works alongside arginine in this cycle and helps clear the byproducts of protein breakdown, ornithine supports healthy protein metabolism and the body's natural recovery processes, which is why it's popular among athletes, often taken on an empty stomach or before bed.*

About the key ingredients

• L-Ornithine (free-form) – 500 mg: A non-essential amino acid central to the urea cycle that supports healthy protein metabolism and the body's nitrogen-clearing, recovery processes.*
• Other ingredients: Cellulose in a plant-based hypromellose (vegetarian) capsule, with no artificial fillers.

Who it's for

NOW® L-Ornithine suits athletes and active adults seeking amino-acid support for protein metabolism, recovery and the body's natural nitrogen-clearing processes. Because ornithine partners with arginine in the urea cycle, it appeals to those training intensely, people interested in supporting recovery and healthy ammonia clearance, and anyone building a targeted amino stack. It's commonly taken on an empty stomach, including before bed, to complement the body's overnight recovery.*
