Our L-arginine makes an economical and effective addition to your dietary plan, especially if you are interested in supporting cardiovascular and immune system health. Each convenient capsule delivers 500 mg of free-form L-arginine.


L-Arginine is a powerful nitric oxide (NO) booster that helps to support vasodilation, which means you’ll benefit from better blood flow throughout your body and increased muscle vascularity!


L-Arginine 500 utilizes a key amino acid responsible for increasing blood flow to muscles. This gives your body the oxygen, nutrients, and blood flow it needs to create intense pumps and help build muscle strength.


When you’re pushing yourself in the gym, your body begins to use up the oxygen in your muscles, lactic acid builds up, and your muscles begin to burn as they fatigue and give out. Generating more oxygen in the muscles by increasing blood flow and nitric oxide can help extend endurance and muscle strength, allowing for more reps and strength to go beyond previous limits!


Improved blood flow increases nutrient transport into the muscles and helps remove ammonia from your muscles. This helps reduce the soreness you may wake up feeling and gets you ready faster for your next workout and to make the most out of every day!
