SIX Nutrition men's l-arginine, free form amino acid supports your cardiovascular system by improving elasticity of the arterial walls. Whether attacking the gap while cycling, training for the marathon or just hoofing it to the bus stop, you need your cardio system performing to spec. That is why l-arginine from six nutrition is your best friend. L-arginine is converted in the body into a chemical called nitric oxide or n-o. N-o has been shown to assist the blood vessels to open wider for improved blood flow. Developed by six nutrition, gluten free, gmp certified, made in the USA, and is paleo friendly.
