L-Ornithine is a non-essential amino acid involved in the urea cycle, where it helps remove excess nitrogen from the body. It is also studied for its role in reducing fatigue and supporting recovery, especially in physically active individuals.
Supplementation with L-Ornithine may help decrease ammonia buildup during prolonged exercise, which can reduce perceived exertion and improve endurance. It is sometimes combined with L-Arginine to enhance growth hormone release and athletic recovery.
Its performance-enhancing potential lies in its ability to reduce fatigue markers and support detoxification during intense training.
