L-ARGININE AMINO ARGININE 500 is a food supplement containing the amino acid L-Arginine in free form. L-Arginine is an amino acid that is not essential for adults because it is synthesized in the body starting from the amino acid L-Ornithine in the urea cycle. L-Arginine participates in the endogenous synthesis of Creatine, a source of cellular energy, and promotes the production of nitric oxide, an endogenous vasodilator. In mammal proteins, all amino acids are found in the levogyra form, so quality dietary supplements prefer the L- form of this amino acid. Solgar KOF-K Certificate No.K-1250.
