L-Arginine Hydrochloride CAS 1119-34-2


Arginine is a semi-essential amino acid. It is a building block of protein that performs a variety of physiological functions. Arginine is an amino acid that the body cannot make naturally. Therefore it is important to consume foods that are rich in Arginine. The physiological processes aided by Arginine include hormone secretion, an increase in growth hormone output, the removal of toxic waste products from the body, and immune system defenses.

Recently, dietary supplements containing Arginine have become popular due to Arginine’s nitric oxide producing ability, its ability to scavenge free radicals, as well as its ability to signal muscle cells, release growth hormone, remove bad cholesterol, and enhance fat metabolism. Arginine helps regulate salt levels in the body.
