L-Arginine hydrochloride

L-arginine is an amino acid that is necessary for the production of protein, also helps rid the body of ammonia (a waste product) and stimulates the release of insulin. In addition, L-arginine is used to make nitric oxide (a compound that relaxes the blood vessels).


Substrate of nitric oxide synthase, which is converted to citrulline and nitric oxide (NO). Induces insulin release by a nitric oxide-dependent mechanism.


Soluble in water (50 mg/mL); slightly soluble in hot alcohol; insoluble in ether.


L-arginine is an amino acid.
