Nitric oxide is a powerful neurotransmitter that helps blood vessels relax and also improves circulation. While L-Arginine can be found in many foods, the average daily intake only meets the minimum requirements to create the necessary amount of nitric oxide. * Research suggests L-Arginine supplementation may also have positive benefits on athletic performance through muscle protein synthesis. Arginine-derived nitric oxide has been shown to help increase mental acuity, improve overall circulation, helps build muscle mass, increase muscle growth and improve endurance.* Doctor's Best L-Arginine HCL powder helps support athletic endurance and helps boost nitric oxide production.
