L-Ornithine - Feed Ingredient

L-Ornithine is a non-proteinogenic amino acid involved in the urea cycle, where it plays a key role in the detoxification and excretion of ammonia from the body. It is naturally synthesized in the liver and does not form part of structural proteins, but it serves important regulatory and metabolic functions.

In equine nutrition, L-ornithine may be included in specialty supplements targeting muscle metabolism, recovery, or liver function. It is not considered an essential amino acid, as it can be synthesized from arginine, but supplemental forms may be used in horses under high metabolic demand or in recovery situations. It is typically provided as L-ornithine hydrochloride, a stable and water-soluble form suitable for feed or supplement inclusion.
