Some of the different uses for arginine

A couple walking down the beach while embracing each other.

If you walk into any health store, it’s pretty easy to become overwhelmed with all of the different, complicated-sounding names on the vitamins and other products that they sell. How often do you look at one of those and think, “what is that even used for?” You wouldn’t be alone in wondering that. There is one more recent product in particular that has a lot of people wondering about how it can be used. That product would be L-arginine (often just called arginine). Because we, here at Natural Arginine, want to make sure that you know what makes our products so great, we thought we would go over what arginine is and how it can be used. Ready to get started and learn about the uses for arginine?

What even is arginine?

Let’s start by giving a good definition of arginine to get the basics out of the way.

Arginine is what’s known as an amino acid. These are important compounds in your system, as they are what makeup proteins. Proteins are what carry out different functions in your body. So, without amino acids, you couldn’t function properly.

As humans, we don’t make our own amino acids. We get them through our diets as they are found in the food we eat. However, sometimes we don’t get enough of certain amino acids to make the proteins we need. That’s where supplements, like arginine, come in. They help you get the amino acids you need to keep things running smoothly.

So, the arginine that you find in stores is a supplement made to help you get the arginine that you may be lacking in your diet. But why do you need arginine in your diet (besides the fact that it’s an amino acid)? What is it used for?

How can it be used?

There are a lot of good things that amino acids can do for you. But what specifically are the uses for arginine? Well, the biggest thing that it does is help widen narrowed blood vessels. It doesn’t take much to see how that could be beneficial. But, to make sure that you fully understand, let’s talk about some of the benefits that that could bring.


Hypertension is an incredibly common issue that could have some serious consequences. It is caused by having narrowed blood vessels and creates high blood pressure. If hypertension goes long enough without being treated, it can cause some real damage to the arteries and may lead to some more serious problems, like heart disease. Since arginine may be able to help widen narrowed blood vessels, it could help reduce hypertension and, as a result, the chances of heart disease.

Pregnancy-related hypertension

No pregnancy is truly easy. After all, you are growing another human being in your body. It takes a lot out of you. One common symptom of pregnancy is hypertension. It’s is a problem for the normal reasons, of course. But there are other reasons why having hypertension during pregnancy could cause even more problems. Hypertension during pregnancy could prevent proper blood flow to the placenta. This could lead to the baby not getting the oxygen and nutrients it needs to grow properly. 

There are a lot of medications out there designed to help with hypertension. However, when you’re pregnant, you have to be very careful about what medication you take, as whatever you take, your baby will be taking as well. This leads a lot of pregnant women to look for alternatives to help with hypertension. Arginine is a potential solution. It is considered to likely be safe for pregnant women to use. That being said, it’s always a good idea to talk with your doctor before you start using any sort of supplement, especially when pregnant.


There is a chance that you’ve heard of angina before. It is a common result of hypertension. It causes sharp chest pains that come on suddenly and can be very alarming the first few times that you experience them. They are a result of the heart not getting enough blood flow to it. It can be incredibly uncomfortable to deal with, so it’s not a surprise that those with angina actively look for any solution they can. Because arginine is able to help with narrowed blood vessels, it’s pretty likely that it could help reduce angina by helping improve blood flow to the heart.

It’s easy to see why so many places have started selling arginine products, there are so many potential uses for arginine. There is some real good that it could do for people. However, it is always good to consult with a doctor before you add any new supplement to your diet, including arginine. There are some medications that it may not mix very well with. So, you will need to be sure to talk with your doctor before using it. You should also continue using any medication that you have been prescribed unless directed to do so by your doctor.
