Pure L-Arginine Powder

What is Doctor's Best L-Arginine Powder?

Doctor's Best L-Arginine Powder helps support athletic endurance and helps increase nitric oxide production. L-arginine is a necessary precursor to creatine that helps supply energy to all the cells in the body. L-arginine also helps regulate blood pressure, helps improve cardiovascular health, helps support a healthy immune system, helps improve blood sugar regulation, and helps support brain health. This Doctor's Best item contains no added colors, flavors, fillers, additives, or unnecessary ingredients.

How does it work?

L-arginine is required to synthesize nitric oxide in the human body. Its main task is to signal blood vessels to relax and expand. When blood vessels dilate, they allow more blood, oxygen, and nutrients to flow to the organs and muscles. Nitric oxide helps create the endothelial relaxation factor, which is needed by the arterial system for expansion and contraction with each heartbeat. Arginine-derived nitric oxide has been shown to help increase mental sharpness, improve overall circulation, help build muscle mass, increase muscle growth, and improve endurance.

Why should I take Doctor's Best L-Arginine Powder?

L-arginine is required to synthesize nitric oxide in the human body. Nitric oxide is a powerful signaling molecule that helps blood vessels relax and also improves circulation. As you age, nitric oxide production decreases. Studies show that an individual who is 40 years old likely produces only about half or less of the amount of nitric oxide than they did at 20 years old. Although L-arginine is found in many foods, the average daily intake only meets the minimum requirements to create the necessary amount of nitric oxide.

Clinical studies have shown that the use of L-arginine during exercise demonstrated an improvement in anaerobic threshold (also known as lactate threshold) and ventilatory threshold (where breathing becomes strained), which lowered oxygen cost during exercise and extended time to exhaustion during heavy-intensity exercise. When you supplement with Doctor's Best L-Arginine, you can train longer while achieving other health benefits.
