What is Pure Nutrition L-Arginine?

Pure Nutrition L-Arginine Capsules are a single-ingredient nitric oxide booster supplement containing free form L-arginine, a conditionally essential amino acid that promotes blood flow and healthy cardiovascular function. 
L-arginine is the original muscle pump ingredient and is often used by athletes, bodybuilders, and gym-goers as a pre-workout nitric oxide (NO) booster. Our L-arginine capsules contain pure free-form L-arginine with no unnecessary binding agents or artificial additives. Since L-arginine is not a stimulant, it can be stacked with your favorite pre-workout supplement for synergistic benefits that will take your training to the next level!

Benefits of L-Arginine

Pure Nutrition L-Arginine Capsules serve as a fast-acting, bioavailable form of L-arginine - the amino acid that your body uses to synthesize nitric oxide (NO). Supplementing with L-arginine before training (especially weight lifting) has been shown to significantly increase plasma L-arginine concentrations and boost NO levels, thereby support better athletic performance.1 
L-arginine supplements have been studied rigorously in recent years as this amino acid serves as a substrate for endothelial nitric oxide synthase (eNOS). When L-arginine is available in the blood, eNOS upregulates production of nitric oxide (NO), resulting in expansion/relaxation of blood vessels. In turn, supplementing with L-arginine has vasodilating benefits and supports proper blood circulation.  
L-arginine also confers general health and longevity benefits by supporting healthy blood pressure levels and immune function. 
In addition, more men are resorting to supplemental L-arginine for promoting erectile quality. Several studies have shown that supplementing with L-arginine may provide natural anti-hypertensive benefits and restore erectile function in men with physiological erectile dysfunction.2,3 This effect appears to be amplified when L-arginine is consumed with yohimbine HCl.4 

Primary Benefits of Pure Nutrition L-Arginine:

  • Rapidly boosts plasma L-arginine levels, resulting in increased nitric oxide (NO) production and enhanced blood flow to skeletal muscle tissue 
  • Promotes greater nutrient and oxygen delivery during exercise, thereby supporting athletic performance and muscle recovery
  • Supports healthy blood pressure levels 
  • Works as a natural supplement for erectile dysfunction 

What Makes Pure Nutrition Free-Form L-Arginine the Best L-Arginine Supplement on the Market?

Similar to Pure Nutrition L-Citrulline Malate powder, our free-form L-arginine powder is produced in the USA in a state-of-the-art cGMP-certified facility that adheres to strict quality control standards. This ensures that you’re getting pure, high-quality, and potent L-arginine in each capsule. Best of all, every serving of Pure Nutrition L-Arginine capsules provides 2,000 mg of free-form L-arginine, making this one of the best values on the market for a nitric oxide booster supplement.
