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.
