Product Description

Available Sizes & Variants:

227 grams L-Ornithine powder - Perfect for daily use at home or in the gym.

Benefits & Features:

  • Supports the urea cycle to reduce ammonia.
  • Athletic recovery is helped as ammonia clearance supports quicker post exercise regeneration and helps you feel less fatigued during tough workouts and may contribute to steadier sleep after exertion.
  • Pure powder, with no fillers, for a clean amino acid boost.
  • Complements protein powder for muscle gain by supporting efficient ammonia removal during intense sessions.
  • Manufactured in a GMP facility by NOW Foods, showcasing decades of quality control.

NOW Foods L-Ornithine powder is produced in a GMP-certified facility, reflecting the brand’s family owned heritage since 1968. This pure amino acid comes as L-ornithine hydrochloride with no anti-caking agents, so lumps may occur. L-Ornithine supports the urea cycle, helping rid the body of ammonia from protein metabolism and may support creatine synthesis for muscle energy. Within the NOW Foods range, n acetylcysteine is another staple for those seeking antioxidant support.

The Active Ingredient Is: L-Ornithine hydrochloride

L-Ornithine, an amino acid form, is involved in everyday metabolic processes and is supplied here as its hydrochloride salt. This description reflects the core ingredient without extra fillers or additives.

Form and source details point to a pure amino acid powder made under standard quality controls, built to support metabolic efficiency and ammonia handling in the body.

What Does L-Ornithine hydrochloride Do?

Scientific evidence suggests L-ornithine may help cut ammonia build-up and back athletic recovery and sleep quality in stressed individuals, with wider links to metabolic health through its role in the urea cycle. Research shows these effects have been seen under controlled conditions.

Dr. Sugino from a university found that L-ornithine supplementation reduced fatigue and improved sleep quality in healthy adults under stress, aligning with EFSA-style functional interpretations.
