    Product Description

    L-Arginine is an amino acid and precursor of nitric oxide (NO).1 L-Arginine is a substrate for NO synthase that is oxidized to form NO and L-citrulline. It enhances NO release in porcine aortic endothelial cells treated with bradykinin (Item No. 37408) or A23187 (Item No. 11016).2 L-Arginine (30 and 300 mg/kg, i.v.) induces dilation of pial arterioles and increases cerebral blood flow in normotensive and spontaneously hypertensive rats.3 It also reduces infarct size by 35 and 28% in normotensive and spontaneously hypertensive rats, respectively, following middle cerebral artery occlusion.

    WARNING This product is not for human or veterinary use.
