All about L-Glutamine

Glutamine is an amino acid found in food that is generated by the body. It helps your immunological and digestive systems. Glutamine is a vital amino acid that serves numerous activities in the body. It is a protein building block and an important component of the immune system. Furthermore, glutamine plays an important role in intestinal health.

This amino acid is produced naturally by your body and can also be found in a variety of foods. However, you may be confused whether you require more glutamine from supplements for optimal health.


What Exactly Is Glutamine?

Glutamine is a kind of amino acid. Amino acids are chemicals that have numerous functions in the body. Their primary function is to act as protein building components. Proteins are essential for organ function. They also help to transfer molecules in the blood and fight off dangerous viruses and germs. It comes in two forms, like many other amino acids: L-glutamine and D-glutamine. They are nearly identical, although their molecular arrangements differ somewhat.

L-Glutamine is the type present in meals and supplements. Some supplements refer to it as L-glutamine, while others just refer to it as glutamine. While L-glutamine is required for protein synthesis and other processes, D-glutamine appears to be inconsequential in living organisms.

Your body can naturally manufacture L-glutamine. It is, in fact, the most abundant amino acid in blood and other bodily fluids.

However, there are situations when your body's glutamine requirements exceed its ability to manufacture it.

As a result, it is classified as a conditionally necessary amino acid, which means that it must be supplied from the diet in some circumstances, such as injury or disease.

Furthermore, glutamine is a critical chemical for the immune system and intestinal function.


It can be found in a variety of foods

Glutamine can be found in a variety of foods. An average diet contains 3 to 6 grams per day, although this can vary depending on your unique diet.

Because of their high protein content, animal foods contain the most.

However, some plant-based meals include a higher proportion of it in their protein.

One study used advanced lab techniques to determine how much L-glutamine is found in various foods.


The following are the percentages of protein made up of L-glutamine in each food:

  • Eggs: 4.4% (0.6 g per 100 g of eggs)
  • Beef: 4.8% (1.2 g per 100 g of beef)
  • Skim milk: 8.1% (0.3 g per 100 g of milk)
  • Tofu: 9.1% (0.6 g per 100 g of tofu)
  • White rice: 11.1% (0.3 g per 100 g of rice)
  • Corn: 16.2% (0.4 g per 100 g of corn)

Although some plant sources, such as white rice and corn, have a high glutamine level, they have relatively low protein values overall. As a result, meat and other animal products are the simplest ways to consume large amounts of it. Unfortunately, many individual foods' glutamine content has not been researched. However, because glutamine is a required component of proteins, glutamine can be found in almost any diet containing protein.

Focusing on having adequate protein in your overall diet is a simple method to potentially enhance your glutamine consumption.


It Is Beneficial to the Immune System

One of glutamine's most essential activities is its role in the immune system.

It is an important source of energy for immune cells such as white blood cells and certain intestinal cells. However, significant traumas, burns, or operations might cause its blood levels to drop. If your body's requirement for glutamine exceeds its ability to create it, it may break down protein stores like muscle to release more of this amino acid. Furthermore, when there is insufficient glutamine available, the immune system's function can be hampered.

As a result, high-protein diets, high-glutamine diets, or glutamine supplements are frequently suggested following serious injuries such as burns.

Glutamine supplements may also improve health, reduce infections, and lead to shorter hospital stays after surgery, according to research.

Furthermore, they have been demonstrated to improve survival and lower medical expenses in critically ill patients.

Glutamine supplementation may also boost immunological function in animals sick with bacteria or viruses, according to other research.

However, there is no clear evidence that advantages exist in healthy adults, and these individuals' needs may be addressed through nutrition and the body's natural production.


It Has an Impact on Intestinal Health

The immune system benefits of glutamine are related to its involvement in gut health.

The intestines constitute the greatest part of the immune system in the human body.

This is due to the numerous immune-functioning intestinal cells, as well as the billions of bacteria that live in your intestines and influence your immunological health.

Glutamine is a vital source of energy for intestinal and immunological cells.

It also helps to maintain the barrier between your intestines and the rest of your body, preventing a leaky gut.

This keeps potentially hazardous germs and poisons from spreading from your intestines to the rest of your body.

It is also necessary for the appropriate growth and maintenance of the cells of the intestine.

Because the intestines play such an important part in the immune system, glutamine may enhance your general immunological health by supporting intestinal cells.


Muscle Gain and Exercise Performance Effects

Because glutamine is a protein building ingredient, some studies have investigated whether taking it as a supplement increases muscle gain or exercise performance.

During six weeks of weight training, 31 persons were given either glutamine or a placebo.

Both groups improved their muscular mass and strength by the end of the research. There were, however, no differences between the two groups.

Additional research has revealed that it has no effect on muscle mass or performance.

However, some studies suggest that glutamine supplementation may help with muscle discomfort and recovery after strenuous exercise.

In fact, one study discovered that glutamine or glutamine with carbs can help lower a fatigue signal in the blood after two hours of jogging.

It has also been used to try to increase the immunological function of athletes, with varying degrees of success.

Other research has indicated that when combined with carbs and specific amino acids, it did not promote the recovery of carbohydrate stores (glycogen) in muscle.

Finally, there is no evidence that these supplements help with muscle building or strength. Other impacts have some limited support, but additional research is needed.

It's also worth noting that many athletes consume a lot of protein in their usual meals, which means they're probably getting a lot of glutamine even without supplements.


Dosage, Safety, and Adverse Reactions

Because glutamine is an amino acid that is naturally synthesized in the body and available in many foods, there is no reason to believe that it is dangerous in small amounts.

A typical diet may contain 3 to 6 grams per day, though this quantity may vary depending on the types and quantities of foods consumed.

Glutamine supplement studies have used a wide range of doses, ranging from about 5 grams per day to high doses of about 45 grams per day for six weeks.

Although there were no known unfavorable side effects with this high dose, blood safety markers were not particularly investigated.

Other studies have found that short-term supplementation of up to 14 grams per day poses little safety risks.

Overall, supplement use is thought to be safe in the short term. However, some scientists are concerned about their long-term use.

Including glutamine in a daily diet may result in a number of modifications in how the body absorbs and processes amino acids. However, the long-term consequences of these modifications are unknown.

As a result, further information about long-term supplementation is required, particularly when high doses are employed.

If you eat an animal-based, high-protein diet as opposed to a plant-based, lower-protein diet, glutamine supplements may not have the same effects.

If you eat a plant-based diet low in glutamine, you may be able to take supplements while still getting a typical daily quantity of it.

If you opt to take a glutamine supplement, you should generally start with a low dose of around 5 grams per day.


In conclusion

L-glutamine and D-glutamine are the two forms of the amino acid glutamine.

L-glutamine is the most essential type, which is naturally synthesized in the body and found in many foods. An average diet contains 3 to 6 grams per day, according to estimates. It fuels immunological and intestinal cells and aids in the maintenance of intestinal connections. Supplementing with it may be good for your immune health and recovery when your body is unable to create ideal amounts, such as during injury or severe illness. Glutamine is another popular sports supplement, but most studies do not support its efficacy. Supplementing appears to be safe in the short term, but additional research on its long-term consequences is required.
