Anyone interested in making sure that their body is getting the right supply of nutrients ought to know a little more about L-Arginine. Also, sometimes known as Nitric Oxide, L-Arginine is a neurotransmitter that helps the brain and body function harmoniously. Evidence has shown that Arginine is excellent for improving circulation and improving heart health – but can it be applied to support a bodybuilder make gains?

At CrazyMass, we went on a mission to find out.

What is L-Arginine? 

Before we dive into how L-Arginine can help a bodybuilder, let’s examine precisely what it is, and summarize the scientific effect it has on the body. L-Arginine is the prerequisite of Nitric oxide; this means that the body needs L-Arginine to create nitric oxide naturally. Arginine is an amino acid that, once digested, will be converted into either nitric acid or insulin or a few other useful bodily substances.

Once converted, the body will use this new nitric acid to widen the blood vessels, which will improve circulation. It stimulates the release growth hormones and can be used for a variety of health conditions. As well as being available in supplement form, L-Arginine is found in the foods that we eat. Some of the most common foods to contain high levels of this amino acid include turkey, pork loin, and pumpkin seeds.

L-Arginine has risen in popularity in recent years as more and more athletes turn to it to enhance performance. It is a safe supplement, not considered to be a steroid. You do not need to supplement to get the benefits of this compound. All you need to do is research the best foods to eat to maintain a steady supply of nitric oxide. If you are seeking to build muscle fast, though, NO is a great option.

L-Arginine Dosage

No standard amount can be taken or is recommended but generally up to 30g is acceptable.  Use caution, though because side effects like nausea and diarrhea can occur.  Start at a low dose for the first week of taking this supplementation and gradually increase where you see results but not the possible side effects, at that point; you have reached a proper dosage for your body.  Use should use a flow cycle where you take it for a while and then don’t take it for a while.  Possibly on or taking it for three months then off or not taking it for two months so that your body doesn’t get used to it and to give your body a break.

As with any supplementation that you might take for any reason you will want to consult with your doctor before taking this.  They will discuss your overall health, any medicines you take that might interact with this supplement, and if it is right for you to choose.

The Benefits of L-Arginine

L-Arginine wouldn’t be a supplement if it weren’t beneficial to the health. It is thought that most of the health benefits found in this particular supplement come from the body’s conversion of the amino acid into nitric oxide. That being said, some of the known health benefits include:

  • Improves heart health. It has been used to treat angina, ease the symptoms of chest pain from clogged arteries, and even help with the level of oxygen in your blood.
  • It can be used as an aid to control blood sugar in patients who have diabetes. This is thanks to its ability to produce insulin, as well as nitric oxide.
  • Soothes inflammation and helps wounds heal faster.

  • Has been shown to relieve symptoms of high blood pressure.

These are just the health benefits derived from the use of L-arginine supplementation specifically. Let’s examine what Nitric Oxide does to the body next.
