Doctor's Best - L-Arginine Powder

Doctor’s Best L-Arginine Powder helps support athletic endurance and helps boost nitric oxide production. L-Arginine is also a necessary precursor to creatine which helps supply energy to all of the cells of 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.

How Does It Work?
L-Arginine is required to synthesize nitric oxide in the human body. Its main job is the signal for blood vessels to relax and
expand. When the blood vessels dilate, they allow more blood, oxygen and nutrients to flow to the organs and muscles. Nitric
oxide helps to product 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 acuity, improve overall circulation, helps
build muscle mass, increase muscle growth and improve endurance.
Nitric oxide is a powerful neurotransmitter that helps blood vessels relax and also improves circulation. As you age, nitric oxide
production falls. Studies show that an individual that is 40 years old is likely only making about half or less the amount of nitric
oxide than they were at the age of 20.
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. Clinical studies have shown that that use of L-Arginine during exercise showed an
improvement in anaerobic threshold (also known as lactate threshold) and ventilatory threshold (at which breathing becomes
laboured), which lowered oxygen cost during exercise and extended time to exhaustion during severe-intensity exercise. When
you supplement with Doctor’s Best L-Arginine, you can work out longer as you achieve other health benefits.
