L-ARGININE has an essential metabolic role in the formation of nitric oxide (NO). Nitric oxide is a gas that has vasodilatory effects increasing blood flow. In 1987 it was discovered that the human body produces small amounts of NO from the amino acid arginine. That is why L-arginine being a precursor of NO, is a supplement widely used in strength sports and resistance for an extra contribution of this amino acid. These physiological reactions allow an increase of blood passage to the muscular zones that take part in the training allowing a greater contribution of oxygen and nutrients, in addition to a greater muscular congestion. The use of L-ARGININE is highly recommended to be taken as a pre-workout supplement and / or as a recovery supplement before bedtime.
