Now Foods Arginine & Ornithine combines two amino acids in effective doses — 500mg L-arginine and 250mg L-ornithine — that work synergistically to support protein metabolism, circulation, and muscle recovery. Ideal for those who train intensely.
✅ 500mg L-arginine + 250mg L-ornithine per capsule
✅ May contribute to protein synthesis and muscle recovery
✅ Supports circulation and physical performance during intense training
✅ Vegetable capsules, free from gluten, soy or artificial ingredients
✅ Produced under GMP standards – guaranteed purity and quality
L-arginine is an amino acid that is a precursor of nitric oxide (NO), a substance that contributes to vasodilation and oxygenation of muscles, especially useful during high-intensity exercise. L-ornithine is involved in the urea cycle, helping to eliminate ammonia and contributing to protein metabolism and post-workout recovery.
Although there are no specific EFSA-authorised health claims for these amino acids, both are widely used in sports nutrition and have been shown to be well tolerated, being recognised for their physiological functions in athletes and active individuals.
Suitable for:
People who practice bodybuilding or intense training
People looking for support for protein synthesis and muscle recovery
Athletes who want to improve muscle oxygenation and physical performance
Not suitable for:
Pregnant, lactating and under 18s
People with a history of liver or kidney problems (consult a doctor)
How to Use: Take 2 capsules daily as needed, preferably with juice or water on an empty stomach, before exercise or at bedtime.
