Are you looking for the Best L-Glutamine powders in the USA?
Don’t worry.
Here, we will list down the Best L-Glutamine Powders available in the USA market.
Choosing the right L-glutamine powder is very important to improve our health.
Glutamine is a type of amino acid that play many important roles in the body. Its main purpose is to serve as a building block for proteins.
L-glutamine is considered conditional and not essential amino acid. Glutamine exists in two parts. One is L-glutamine (levorotary) and the second is D-glutamine (dextrorotary).
We get all the benefits from L-glutamine whereas D-glutamine remains inactive in the body. That’s why we should buy glutamine supplements that only contain L-glutamine and not D-glutamine.
Before we start listing down the best L glutamine supplement, let me give you additional information.

1. Why Do You Need L-Glutamine Powder Supplement?
L-glutamine can be produced by our bodies then why do we need to take its supplements?
The reason is simple and clear.
In the case of any injury or illness, you need more glutamine for recovery but your body can’t produce L-glutamine in sufficient amounts.
And it starts breaking down the muscles to release extra amino acids in the body.
In such cases, it becomes necessary to supplement your body with additional L-glutamine.
2. Key Benefits of Consuming L-Glutamine powder
L-glutamine is an amino acid that is a basic component of protein in your body and having a sufficient amount of protein always benefits us.
Here are several health benefits of consuming L-glutamine supplements.

3. How to Choose The Best L-Glutamine Powders?
There are many L-Glutamine powders available in the USA market, so it can be tough to know which one is the best.
That’s why here I mentioned a few points that will help you choose the best L-glutamine powder.
This is similar to buying guide.
1) It Must Contain Only L-Glutamine
There are lots of companies that add other amino acids along with L-glutamine.
If you consume such supplement powders, you will not get the required benefits of L-glutamine.
So, always make sure that your chosen L-glutamine powders contain only one amino acid i.e, Glutamine.
You also have to make sure that the glutamine of the product is strictly L type and not D type because all the health benefits of glutamine come from L type.
2) It Must Be Unflavored
I don’t mind if you want the flavored one but there are two major reasons behind choosing the unflavored one.
The first reason is that you don’t have to worry about the artificial flavors added to the supplement powder. The second reason is that you can use such unflavored powders in any drink without altering their tastes.
3) L-glutamine Powder Must Be Free From Allergens
Many people are allergic to several substances such as lactose, gluten, soy, egg, tree nuts, etc.
If you are one of these people then you must ensure that your chosen L-glutamine powder is allergen-free.
4) Better If Micronized
If the L-glutamine powder is micronized that means your stomach will easily absorb this powder. Here, not all the products mentioned are micronized.
If you want the micronized one, you should for NAKED Nutrition’s L-Glutamine powder.
5) Free From Fillers & Preservatives
Fillers are the product used to increase the quantity of the product. It is mostly required in capsules and not in powders.
So, if any L-glutamine powder contains fillers then stay away from it. Also, avoid purchasing if it contains preservatives or any other chemicals.
All the products mentioned here are free from fillers and preservatives.
Now, we will list down the best L-glutamine powder available in the USA market.

Research shows that L-glutamine supplements are useful to people who have any kind of health issues such as low immunity, infection, burned, leaky gut, IBS, etc.
Also, people who take low protein in their diet may need these supplements.
If you are completely healthy and taking a protein-rich diet (especially, animal-based protein) then you don’t need to take L-glutamine supplements.
It is because your body will produce enough L-glutamine from this diet naturally.
If you are aiming for muscle gain and increasing workout performance then again I won’t recommend you to consume them.
It is because almost all the research denies its benefits to muscle gain and increasing workout performance.

In several conditions, you can consume L-glutamine.
Such conditions are,
- Your diet lack high protein (especially animal-based protein)

- Infection
- Inflammatory conditions such as leaky gut
- Burns
- If you want a fast recovery after surgery
In such cases, you can consume (not necessarily) L-glutamine supplements.
7. Why Choose L-Glutamine in Powder Form Over Capsule or Tablet Form?
However, it is a personal choice to choose the way of consuming L-glutamine.
But, there are a few advantages of consuming L-glutamine supplements in powder form.
Here are they,
- Multiple ways of consumption
- High absorbability
- Easy on stomach
- The higher dose of L-glutamine in a single serving than in a capsule

If you want to consume it in capsule form, here is the best L-Glutamine capsule supplement.
