Informational guide to L-Glutamine Supplements

What Are L-Glutamine Supplements?

L-glutamine is a non-essential amino acid, which means that the body produces it naturally in the body. It can also be found in your diet through food such as spinach, chicken, cabbage, fish, tofu and more.

That said, during times of bodily stress, like during a workout, L-glutamine won’t be produced as well, naturally. This is where L-glutamine supplements come in, by providing you with the amino acids you need to function correctly.

When to Use an L-Glutamine Supplement

At times of stress—and working out can be one of those times—your body may lack the L-glutamine it requires to cope. This is where an L-glutamine supplement will come in handy, as it has a number of benefits with regards to these problems.

But what exactly are all of these benefits?

The Benefits of L-Glutamine

There are a number of great ways that L-glutamine can help you:

  • Protects against the negative effects of over-training.
  • Helps your muscles recover.
  • Improves the health of your immune system.
  • Promotes muscle repair and growth.
  • Promotes and preserves lean muscle mass.
  • Keeps your intestinal health up-to-scratch.

What to Look for in the Best L-Glutamine Supplements

Before we go into detail on the five best L-glutamine supplements on the market, there are some features of these supplements that you need to be aware of. You can then make the most informed decision for your needs.


All of our options below fit the bill here, but what does this mean? Well, amino acids are used in muscle recovery and growth but are commonly absorbed as chains. This means the chains must split up before they can link back together again to be used for specific purposes.

When your body is trying to absorb L-glutamine into the body, it’s much easier to do so if the cells are free-form. This means they’re not linked in chains to other amino acids, so can be easily utilized in the body to form new chains.

Servings Per Container

In order to get the best for your buck, the amount of servings per container is something to watch out for. Considering the similarities between each of the products below, this is what may make a product stand out to you. Below, we have products which contain between 40 and 200 servings per container, so take your pick!

FDA Approval

The FDA approves products, brands or facilities where the products are made, to ensure they fit certain health guidelines.

If you’re concerned about your health when it comes to consuming supplements, this may be something to be aware of. Below, we’ve specified which of our favorite products are FDA-approved, or the like, so you can purchase a product you trust.

Company Ethos

We’ve highlighted our favorite elements about each company behind the supplements, so you know exactly what you may be buying into. For example, some of our companies donate to charity, while others ensure their products are allergy-free. Whatever you fancy, there’s probably an option for you.


Considering the fact that almost all of our options contain five grams of L-glutamine, it makes it difficult to choose a favorite. This is where we have to take everything into consideration. This includes the number of servings per container, quality, safety and the company ethos.

When we break it down, our favorite option of the five has to be the Now Foods L-Glutamine Pure Powder. This is because, not only does it contain a decent amount of servings per container, the company also has a great ethos. This includes ensuring everybody has the support and knowledge to exercise.

Furthermore, its clinical research and promise to uphold FDA guidelines make it a trustworthy option. This way, you’ll be getting the best for your money.
