L-Arginine has become one of the most popular sports nutrition supplements on the market today – and for good reason. This amino acid is known to promote heart health, wound healing, kidney function, immune system function, and hormone function. L-Arginine transforms into nitric oxide in the body, which relaxes blood vessels, improves circulation, and helps the body build protein.

Challenger Nutrition’s L-Arginine capsules contain 1,000 mg per serving, the ideal amount for athletes and bodybuilders looking to maintain optimal health. Not only can L-Arginine improve your performance at the gym, but studies have also linked it to fewer muscle aches and pains, reduced risk of heart disease, preventing immune system disorders, and for erectile dysfunction. These convenient capsules are a must for Challengers like you who want to live a healthy and active lifestyle.
