L-Arginine is a non-essential amino acid that can be produced naturally by the human body, as well as being found in a number of dietary sources, including nuts, dairy, and meat sources. Just because it is non-essential however, this does not mean that arginine supplementation is not beneficial, because truthfully, it is, for a variety of different reasons. Studies have found that increased L-Arginine consumption, can provide a number of benefits for the human body, as well as for the physique, and athletic performance in general. Athletes and bodybuilders often supplement with L-Arginine, and include it in part of their muscle-building supplement stack. The benefits of L-Arginine come from the fact that it plays a vital role in protein synthesis, as well as helping to function as a precursor for the production of Nitric Oxide, which in itself, helps provide numerous athletic performance advantages to the human body. Basically, within the body, L-Arginine is converted into Nitric Oxide, which in turn then causes the blood vessels to widen and dilate, due to the fact that Nitric Oxide functions as a potent vasodilator. As the blood vessels widen and expand, this in turn allows more oxygenated blood, rich in nutrients, to pass through the vessels and be transported around the body and delivered to the major organs that happen to require it. On top of that however, it has also been linked with an increase in insulin production and growth hormone production, making it highly beneficial for bodybuilders and individuals looking to increase their lean muscle mass. On top of that, it has been found to play a crucial role in protein synthesis, making it essential for the growth and repair of muscle tissues, especially tissues following an extensive workout.CANADIAN PROTEIN - We are obsessed with providing Canada supplement customers great nutritional products, quality and customer service.

Put simply, if you look better as you lift, this will serve as a psychological boost and so you're far more likely to work that little bit harder in the gym. BUILDS MUSCLE MASS - L-Arginine also plays a key role in protein synthesis, which is when the body synthesises new muscle proteins to replace worn and damaged ones as a result of an extensive workout or bout of strenuous physical exercise. Protein synthesis plays a key role in post-workout growth and recovery, making L-Arginine a very beneficial amino acid in terms of post-workout recovery. NITRIC ACID BOOSTER - This amino acid has been found to play such a key role in athletic performance because it is converted into Nitric Oxide. This Nitric Oxide dilates the blood vessels and allows more oxygenated rich blood to be carried around them. More oxygen and nutrients can therefore be supplied to the awaiting muscle cells in the body, which in turn will help to provide them with more energy, so they will be able to function harder and for longer, before they begin to fatigue. 5g PER SERVING - The benefits of L-Arginine come from the fact that it plays a vital role in protein synthesis, as well as helping to function as a precursor for the production of Nitric Oxide, which in itself, helps provide numerous athletic performance advantages to the human body. 5g PER SERVING - The benefits of L-Arginine come from the fact that it plays a vital role in protein synthesis, as well as helping to function as a precursor for the production of Nitric Oxide, which in itself, helps provide numerous athletic performance advantages to the human body.
