Shopping guide

The wear and tear of training, stress and lifestyle can sometimes lower the levels of glutamine in our body, therefore it is important to supplement these deficits through nutritional supplements. In the following guide to buying the best glutamine, we detail the aspects that you must take into account when choosing one.

Functions and source of obtaining

Glutamine is an essential amino acid in our body, that is, our body is capable of producing it by itself. But, in situations of stress, or high-intensity sports practices, these levels can drop to such a degree that it is essential to supplement any deficit with nutritional supplements. This amino acid is responsible for performing different functions, one of them is to synthesize essential proteins for tissue growth; in addition to regulating the pH thanks to the nitrogen molecules.

And it is that glutamine is not only responsible for improving our muscles, it also stimulates the proper functioning of the brain, by helping to maintain memory and lower levels of stress and irritability.

The main sources of obtaining this component are found in foods of animal origin such as pork, beef, poultry and fish, eggs, milk, cheese and yogurt; in fruits such as papaya, miso and beans, and vegetables such as spinach, eggplant, carrots and cabbage.

These raw materials are exposed to a natural fermentation process, and from there the glutamine that is used in the different food supplements is obtained. In the market you can find it in Kosher presentations, suitable for vegans and vegetarians; as well as free of allergenic components such as gluten, soy, egg, dairy, artificial flavors, etc.


As we have already mentioned, over the years it has been shown, through various studies, that there are more and more benefits that glutamine provides in our body.

This amino acid is not only indicated for athletes who perform high-intensity sports, it is also recommended for people who lead a sedentary or busy lifestyle, under high stress levels. Therefore, before worrying about how much a presentation costs, it is important to analyze that opting for a glutamine supplement is investing in physical, emotional and brain health.

Similarly, we can highlight that glutamine combats depression and anxiety, improves sleep, protects the immune system by increasing defenses, accelerates the recovery process of muscles after physical exercise and increases muscle mass. In turn, it is indicated to avoid catabolism, and stimulate anabolism during protein synthesis.

Presentation and types of supplements

When making a comparison of glutamines, we can find it in two types of presentation, powder and capsules. The amino acid present in a powder format is indicated for athletes who must consume a dose greater than 5 grams of glutamine, it can be mixed with water or other protein drinks to create personalized supplements, and you can also get it in different flavors. However, most of the packages that contain this product are usually very large, so it could be difficult if you want to take it to another place.

In contrast, glutamine capsules are small and compact, easy to carry around. They are recommended for users who have busy lifestyles and do not have time to prepare a protein supplement powder.

Most of these are tasteless and soft in texture, making them very easy to swallow. In general, this presentation usually provides only 2 grams of glutamine, although there are exceptions, a composition of 5 grams of glutamine, but the size of the capsule is very large, making it difficult and uncomfortable to ingest.

Interaction with other medications

In the market we can find food supplements that have glutamine as the only component. Which is a good and economical alternative, since it can also be combined with other nutritional supplements such as protein shakes, products with BCAAs or other essential vitamins for athletes that increase their cost.

Some supplements, meanwhile, contain loads of glutamine mixed with other components such as BCAA amino acids, obtaining 2 benefits in a single formula. However, before carrying out any supplementation, it is advisable to consult a medical specialist or nutritionist about the components that can easily interact with the raw material of glutamine, since it is important not to self-medicate in any case.

Frequently asked questions

Q1: How to use glutamine?

The first thing we must take into account when using glutamine supplements is that it is really necessary to consume it, this is determined by observing if you are losing muscle mass after carrying out demanding exercise routines for a while, or if you feel fatigue or a lot of pain in your muscles after exercising.

A medical evaluation will also be able to tell you if you need to take this product or not. Following this idea, the specialist will recommend the appropriate dose to cover said deficiency and the appropriate time for its intake during the day.

Q2: How to take glutamine?

To start taking glutamine for the first time, it must be done progressively and in minimum doses, to test the tolerance that the body has to the supplement and the side effects that may occur.

After verifying that these products do not cause negative impacts on our body, the amount can be gradually increased, until reaching that indicated by a specialist. Generally, micronized glutamine powder is dissolved in water or other pre- and post-workout drinks, with the recommended amount being 5 to 10 grams per day, divided into 2 servings.

Q3: Where does glutamine come from?

Mainly, glutamine is generated by our own body naturally, since it is one of the 20 amino acids that are most abundant in our body.

However, we can also obtain it through foods of animal and vegetable origin, such as parsley, nuts, spinach, meat and dairy products; although these should be consumed raw and not cooked, since when cooked they lose all the glutamine properties they may contain.

Q4: Which is better BCAA or glutamine?

It is important to note that BCAAs (Leucine, Isoleucine and Valine) are essential amino acids, that is, they cannot be synthesized by our body, so we must consume them through food or vitamin supplements. For its part, glutamine is a non-essential amino acid, since our body is capable of producing it on its own; although in situations of stress or intense and prolonged training they can lower their levels, to the point of needing to fill this deficit.

Each one has positive effects on our muscles, since both are responsible in different ways for repairing injuries caused during training and increasing muscle mass; only that BCAAs are indicated for athletes who need extra energy power; while glutamine is focused to be used by any user from athletes to sedentary people. The choice is yours.

Q5: Is glutamine fattening?

As long as it is taken daily in amounts indicated by nutritional or medical specialists, glutamine does not generate negative effects on our body. However, sometimes there is a tendency to confuse the increase in muscle mass that this may cause, with a weight gain. On the other hand, if this supplement is consumed excessively, without any control, recommendation or without physical training, it could intensify the accumulation of fat and therefore weight gain.

Q6: Which is better, glutamine powder or pills?

You can consume glutamine both in powder and in pill form, it’s just a matter of taste and needs. For example, glutamine powder is recommended for athletes who require the intake of high doses of glutamine (5g), since they are easier to take, can be combined with other drinks and some bring different pleasant flavors to the palate. For their part, the capsules are indicated for people with busy lifestyles, since the doses of these are easier to carry everywhere.

Q7: When to take glutamine?

Mostly glutamine should be taken by athletes who perform high-intensity exercises, or users who lead a busy or stressful lifestyle. We recommend that you first consult a medical specialist, so that he or she can tell you at what time of the day you should take the shots, and the ideal dose according to your age, gender and activity that you do. However, this product is indicated to be consumed when getting up, before and after training, and at bedtime.

Q8: Which is better glutamine or creatine?

Both amino acids are important for those athletes who perform exercises that demand strength and endurance. Glutamine is responsible for repairing injuries, raising the immune system and increasing muscle mass in your body; while creatine provides energy to your muscles quickly and powerfully. That said, it’s just a matter of analyzing what your body really needs.
