L-Arginine

L-Arginine

Circulation, hoof, and skin support

L-arginine is a functional amino acid involved in several important metabolic pathways. One of its key roles is serving as a precursor for nitric oxide, a signaling molecule that helps regulate blood flow and vascular function.

Healthy circulation supports the delivery of oxygen and nutrients to tissues with high renewal needs, such as the skin and hoof. This makes arginine relevant for dogs in formulas aimed at maintaining healthy skin, and for horses where hoof quality and metabolic balance are important.

Nitric oxide is also involved in normal skin physiology, including barrier function, immune signaling, and tissue renewal. Through its role in nitric oxide production, arginine contributes to overall tissue resilience and physiological balance (E Seifter, 1978; Siani, 2013).
