                                Arginine is a semi-essential amino acid that serves as a precursor for nitric oxide, a molecule critical for regulating blood flow. A significant depletion in this amino acid, a condition known as low arginine, can interfere with vital physiological processes and manifest through a variety of health symptoms.
