What is L-Arginine Powder?

L-Arginine is a versatile amino acid serving as a precursor for the manufacturing of proteins, nitric oxide, urea, glutamate, and creatine in the body. Increased L-Arginine in the body may lead to an increase of Nitric Oxide (NO) production, which may also increase blood flow during exercise, allowing for muscles to perform longer under stress. The vasodilation effect of Nitric Oxide may provide a fuller and more satisfying pump during workouts.† Nitric Oxide (NO) production puts the urea cycle into overdrive, allowing it to absorb more ammonia (composed of nitrogen molecules) produced by working muscles. Removal of ammonia from the brain is believed to have detoxification and neuroprotective qualities.†

L-Arginine benefits may include:

  • Healthy Vasodilation†
  • Improved Nitric Oxide Production†
  • Increased Muscle Protein Synthesis†

How Does Arginine Work?
Arginine is used to synthesize nitric oxide, which helps blood vessels to relax and expand, making it integral in regulating healthy blood flow and assisting in regulating blood pressure. In addition to acting as a vasodilator, it also supports muscle protein synthesis. With the increase in Nitric Oxide production, blood is able to flow more freely to muscles that are being exercised and allow for an increase in oxygen and nutrient delivery. With Arginine helping to assist blood flow, it may also benefit cardiovascular health as well as blood pressure.

    I bought a kilo and have been stacking this with several other amino acids and feel it works great! I make a really delicious drink with brown rice protein and stevia with a stack of amino acids and feel like it works really well! I like how its has no additives. I cant find this kind of deal in any vitamin store. I think it works well and feeling stronger. I will definitely purchase more in the near future!
