- Glutamine is a vital amino acid used in dietary supplements.
- Supplements contain either L-Glutamine or glutamine peptides.
- Glutamine peptides may contain gluten, but L-Glutamine does not.
- Glutamine supplements may contain other gluten-rich ingredients.
If you have a strict gym trainer, you have probably been prescribed to consume a glutamine supplement. It is an amino acid that helps the body perform essential bodily processes, gut functions, and the immune system. It is also crucial in times of stress. But the big question is, is glutamine gluten free?
It’s easy to get confused. After all, “glutamine” sounds similar to ‘gluten’. However, the two are not the same. Of the two types of glutamine, L-Glutamine is gluten free, but glutamine peptides may not be so. Also, glutamine supplements may contain fillers or additives with gluten in them.
Is Glutamine Gluten Free?

Glutamine is one of the most common ingredients present in health supplements. It is helpful in the body’s recovery process and is also known to help with digestive issues. However, for athletes and fitness freaks with celiac disease or gluten allergy, there’s always that one question: is there gluten in it?
The first thing you need to understand is that it is an amino acid produced by our body. It can also be present naturally in various protein-rich foods, including both plant and animal sources. There are two types of glutamine present in health supplements: L-Glutamine and glutamine peptides.
Of these, L-Glutamine is free from glutamine. It is widely used in gluten free supplements because it is free from gluten. You can consume them without worrying about allergic reactions. Interestingly, wheat gluten has glutamic acid. But people who react to gluten don’t have allergic reactions from L-Glutamine.
Glutamine bonded peptides, on the other hand, might be derived from wheat. If you are allergic to gluten, you should avoid having any glutamine supplement that contains glutamine peptides. The brand is not obligated to reveal the source of glutamine peptides used in its product. So it is better to avoid it.
Instead, choose L-Glutamine supplements. This will ensure that you do not get allergic reactions to the gluten peptides if extracted from gluten-containing sources. Even though gluten peptides are considered more effective, it is better to choose L-Glutamine supplements to avoid health issues.
When buying glutamine supplements, you also need to be careful about the other ingredients in the product. Supplements often contain many flavoring agents, fillers, preservatives, and other additives. It is essential to make sure that these additional ingredients do not have gluten hiding in them.
To ensure that you get the best of the glutamine products without getting allergic reactions, you should always check the ingredients label. That way, you can identify if there’s any gluten ingredient in it. You can reach out to brands to know more. The ideal solution is to buy certified gluten free supplements.

Why is Glutamine Gluten Free?
Glutamine is an amino acid that is produced in the human body. Hence, it is considered a non-essential amino acid. There are two reasons why the confusion between glutamine and gluten exists. The first reason is apparent – the name. The second reason is that glutamine is present in gluten.
Glutamine is, however, one of the many amino acids that together form gluten protein. In other words, glutamine might be a constituent of gluten, but the two are not the same. For one, the human body can produce glutamine but not gluten. It is only made in certain grains, i.e., wheat, rye, and barley.
L-Glutamine, an amino acid, is a derivative of glutamic acid and is quite different from any protein like gluten. The chemical ingredients in L-Glutamine hardly include any gluten impurities. This makes L-Glutamine gluten free. But if glutamine peptides are not the same. That’s because they are proteins.
If peptides are derived from gluten grains, they may contain gluten. Whether you’re allergic to gluten or have celiac disease, your body treats gluten, which is a protein, as a foreign body and reacts to it. If glutamine peptides, which are also proteins, are derived from gluten, they can trigger your body.
While glutamine peptides get absorbed by the body faster, L-Glutamine is still the choice for people leading a gluten free lifestyle. Thus, L-Glutamine is widely used in gluten free foods. It is mainly used in processed foods and dietary supplements rather than recipes used for cooking food every day.
Glutamine is also found in many natural substances that can be added to your daily diet. These include animal proteins like meat, fish, and dairy products. However, if you prefer vegetarian options, you can stick to plant-based alternatives, such as tofu, lentils, beans, peas, spinach, beets, cabbage, and more.
How Glutamine Helps Us

When the human body does not get sufficient glucose sources, it starts to convert glutamine into glucose. In other words, glutamine acts as a fuel source. Glutamine plays an essential role in our body by doing the following:
- It prevents bacterial translocation and promotes mucosal integrity in the gut;
- It provides fuel to the cells in the immune system, and
- It improves the balance and movement of nitrogen in the body during stress.
Even though our body produces glutamine, we may still need a supplement. Almost all our tissues synthesize glutamine. But if you have metabolic issues, your body will demand more glutamine. In such a situation, you’ll need to add glutamine to your body with supplementation.
A person might need glutamine supplementation when they suffer from conditions such as –
- bowel disease
- trauma
- immune disorder
- sepsis
- temporary metabolic needs
- serious health conditions
- immune disorders
- intense treatments
So it is not just people with rigorous fitness routines who need to glutamine. Sometimes, the body might demand it because the glutamine requirements of the body are not being met.
Does Glutamine Help People with Celiac Disease?
Ongoing studies suggest that glutamine can improve celiac patients’ overall health with its ability to boost cell growth in the intestine and heal a leaky gut. Besides, since celiac patients have protein losses, glutamine can be utilized by their bodies. This amino acid acts as a building block of proteins.
Many people with celiac disease claim that glutamine has helped in reducing the symptoms of their condition. But then again, some people are sensitive to it. So, it is essential to consult a physician about the proper dosage and product. For many celiac patients, glutamine is a vital part of everyday diet.
Many people with celiac disease use glutamine as a kind of anti-gluten measure. Of course, that doesn’t mean they eat gluten, and glutamine saves them. But if they accidentally consume gluten, glutamine helps many celiac patients to calm their guts. They claim that glutamine can keep symptoms at bay.
Final Lines
Glutamine supplements are quite helpful in keeping our gut and immune system. It helps muscles to grow and recover. Glutamine supplementation is an indispensable part of your diet if you’re into fitness and athletics. But you also need supplements if your body is stressed and can’t make glutamine.
Though glutamine peptides get absorbed in the body fast, people allergic to gluten should stay away from this protein, lest it’s derived from wheat. Instead, go for L-Glutamine, an amino acid that does not cause allergic reactions. You should also check for other gluten-rich ingredients in a supplement.
