L-Arginine - Feed Ingredient

L-Arginine is a conditionally essential amino acid that plays a key role in protein synthesis, nitric oxide production, and immune function in horses. It serves as a precursor for nitric oxide, a molecule involved in vasodilation and blood flow regulation, which may contribute to cardiovascular function and muscle oxygenation.

While horses can typically synthesize arginine from other amino acids, certain conditions—such as growth, intense exercise, or metabolic stress—may increase the need for dietary supplementation.

The following equine feeds, supplements and products contain L-Arginine as an ingredient.
