                                L-arginine hydrochloride, commonly referred to as HCl L-arginine, is a form of the amino acid L-arginine that is bonded with a hydrogen chloride molecule. This modification is primarily designed to improve the compound's stability, water solubility, and absorption rate, making it a common ingredient in many dietary supplements. While the core physiological functions remain similar to standard L-arginine, the chemical alteration offers key advantages for manufacturers and consumers.
