L-Carnosine - Feed Ingredient

L-Carnosine is a naturally occurring dipeptide composed of the amino acids beta-alanine and L-histidine. It is found in high concentrations in muscle and nervous tissue, where it functions as a pH buffer and antioxidant. In equine nutrition, L-carnosine is used as a specialty supplement ingredient, particularly in formulations targeting muscle function, exercise recovery, or oxidative stress.

L-Carnosine is not a dietary essential amino acid but is synthesized endogenously in the body. However, supplemental forms may be used in performance horses to support muscle buffering capacity during high-intensity exercise. It is typically provided in purified form and included in low amounts due to its potency.

While data specific to horses is limited, L-carnosine is generally regarded as safe.
