Doctor’s Best L-Arginine powder helps support athletic endurance and nitric oxide production. L-arginine is an amino acid that helps support cardiovascular health and the regulation of blood pressure, a healthy immune system, blood sugar regulation, and brain health. Nitric oxide is an essential molecule that is important for many aspects of health, allowing blood, nutrients and oxygen to travel to every part of your body effectively and efficiently.
L-arginine is an amino acid that helps the body build protein and produce nitric oxide. As you age, nitric oxide production falls. Research shows that an individual that is 40 years old may only be making about half (or less) the amount of nitric oxide than they were at the age of 20. The use of L-arginine during exercise supports anaerobic and ventilatory thresholds, which supports a decrease in oxygen cost during exercise and extended time to exhaustion. Because L-arginine acts as a vasodilator, opening (dilating) blood vessels, many people take oral L-arginine to support heart conditions and erectile dysfunction.
L-arginine is required to synthesise nitric oxide in the human body. Nitric oxide is a powerful neurotransmitter that helps blood vessels relax and supports 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 NO. Research suggests that L-arginine supplementation may also have positive benefits on athletic performance through muscle protein synthesis. Arginine-derived nitric oxide has been shown to help support mental acuity, overall circulation, muscle mass, muscle growth, and endurance.
