L-Arginine Hydrochloride

                                   
 

The main functional role of L-arginine hydrochloride stems from its status as a direct precursor of nitric oxide (NO), which functions by dilating blood vessels and improving blood flow. Its main application areas include: supporting cardiovascular system health (improving blood pressure, blood flow, and endothelial function), enhancing athletic performance and recovery, supporting the immune system, promoting wound healing, and improving male erectile function.
