What is L-Arginine Powder?
Doctor’s Best L-Arginine Powder helps support athletic endurance and helps boost nitric oxide production. L-Arginine is 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. This Doctor’s Best item contains no added colours, flavours, fillers, additives or unnecessary ingredients.ut, for up to 3 hours – after just a single dose! With continued use, nitric oxide levels build over time, leading to even better blood flow and vessel flexibility.
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.
