L-Arginine

L-Arginine is a conditionally essential amino acid found in the diet. It is the amino acid that directly produces Nitric Oxide via the nitric oxide synthase enzymes.


For those looking to enhance athletic performance or increase muscle mass, arginine supplementation has been shown to be extremely beneficial. As a natural precursor to nitric oxide, arginine promotes vasodilation for intense pumps that drive the next level of athletic performance.


Nutricost L-Arginine provides an incredible 5g serving of pure, unhindered L-Arginine in its most bioavailable form. Add to water, juice, or your favorite protein shake to augment nitric oxide production and enhance aerobic exercise capacity. Studies have shown that dietary nitrate supplementation reduces the oxygen cost of low intensity exercise and enhances tolerance to high intensity exercise, dramatically enhancing athletic performance.


Adding L-Arginine to your daily routine also helps to reduce lactate and ammonia build-up during exercise, warding off fatigue. Arginine also acts as a natural precursor to creatine, stimulates growth hormone production, and reduces recovery time. The importance of L-Arginine in any athlete’s diet can’t be overstressed – and Nutricost L-Arginine makes it ultra convenient and easily affordable to make this happen.


Nutricost uses an exclusive multi-stage process that derives this powerful amino monopeptide from a pure vegetable base for no contaminants or fillers.
