Glutamine: 7 Benefits, Uses, and 4 Side Effects, Food Sources

Glutamine: Benefits, Uses, and Side Effects
The body naturally makes glutamine in the muscles, which is transferred by the blood into different organ systems.

Amino acids are the building blocks of proteins in cells and tissues and are the second most abundant compound found in mammals after water.

The availability of amino acids is of fundamental importance for cell survival, maintenance, and proliferation.

Among the 20 amino acids, glutamine is the most abundant and versatile amino acid responsible for intermediary metabolism and immune function.

What is glutamine?

Glutamine is a nonessential amino acid that serves as a building block for proteins.

It is considered a conditionally essential amino acid, which means it must be obtained from the diet under certain circumstances, such as injury or illness.

It is synthesized from glutamic acid and ammonia and is involved in many metabolic processes.

The two different forms of glutamine include L-glutamine (found in foods and man-made supplements) and D-glutamine (relatively unimportant in humans).

Glutamine supports several functions of the body, including:

  • Making proteins for muscle tissues
  • Fueling cells that protect the stomach and the intestines (enterocytes)
  • Supporting immune system cells
  • Helping the liver detoxify foreign substances

Manmade versions or glutamine supplements are available in the form of:

  • Capsule
  • Tablet
  • Powder for solution
  • Packet
  • Powder for suspension

Which foods should you eat to get glutamine?

The body naturally makes glutamine in the muscles, which is transferred by the blood into different organ systems.

Because animal products, such as meat, eggs, and beef, are high in protein, they are the simplest ways to get high amounts of glutamine as well.

However, some plant-based foods have an adequate amount of glutamine, such as wheat, peanuts, corn, tofu, and milk.

The deficiency of glutamine is rare and is often caused by genetic disorders rather than inadequate intake.

What is glutamine used for?

Endari (glutamine) is approved by the U.S. Food and Drug Administration as a prescription drug for sickle cell disease.

Other conditions wherein glutamine is possibly effective include:

What amount of glutamine supplement intake is considered safe?

The amount, dosage, and frequency of glutamine supplements depend on the reason for prescription and the general condition of the patient.

According to an estimate, people consume about three to six grams of glutamine daily in the diet

Some clinical studies have speculated that doses of 5 to 45 grams per day for up to six weeks are considered safe with no negative side effects.

7 benefits of glutamine

Research suggests that glutamine supplements may offer some health benefits, but studies are underway to confirm the potential of glutamine to prevent or treat certain conditions.

  1. Improves recovery times and reduces complications
    • It may help people with gut conditions such as Crohn’s disease, celiac disease, and gut inflammation.
  2. Boosts immunity
    • It acts directly on gut-associated lymphoid tissue and stimulates overall immune function.
    • Glutamine supplements might help the gut, immune system, and other processes function properly, especially in times of stress, such as trauma, injury, or illness.
    • It is the main fuel source for lymphocytes, and white blood cells that fight infection and diseases.
  3. Promotes intestinal health
    • The amino acid helps maintain the intestinal lining, ensuring that the body absorbs the nutrients it needs.
    • It supports overall good health and protects against serious problems, such as leaky gut syndrome.
    • It plays a major role to protect the integrity of the gastrointestinal tract, especially the large intestine.
  4. Helps recover muscle
    • Glutamine supplements may act as fitness supplement that promotes muscle gain and fat burn.
    • It may help reduce fatigue and improve exercise recovery.
    • In addition, it may reduce muscle damage and aid in exercise performances.
  5. May help ease the effects of cancer treatments, such as muscle wasting, oral inflammation, nausea, vomiting, and diarrhea.
  6. Glutamine supplements are linked with shorter hospital stays and lower mortality rates for critically ill patients.
  7. Reduces the acute complications of sickle cell disease in adults and children.

4 potential side effects of glutamine

  1. Long-term impact
    • Excessive intake over time may change the way the body distributes and uses amino acids, which may raise the risk of health problems.
  2. Hazardous side effects
  3. May worsen liver and kidney diseases
    • People with liver and kidney conditions need to be extra cautious before taking a glutamine supplement.
  4. Pregnancy
    • There is not enough evidence or conclusive studies to confirm the safety of glutamine in pregnant or breastfeeding women.
    • Do not use glutamine until advised by a medical health professional.
