Glutamine

Glutamine is an amino acid that is used in the biosynthesis of proteins. It is considered a conditionally essential amino acid because it can be made in the body, but in some situations, the body's demand for glutamine increases and it must be obtained from the diet.

Function

Glutamine plays key roles in the immune system, intestinal health, and muscle growth. It is also involved in the production of other amino acids, sugar, and ammonia.

Dietary Sources

Glutamine is found in many foods, including beef, chicken, fish, eggs, milk, dairy products, wheat, cabbage, beets, beans, spinach, and parsley.

Supplements

Glutamine supplements are often used in the healthcare setting to prevent weight loss in patients undergoing chemotherapy or radiation therapy. They are also used to improve healing after surgery or trauma, and to treat leaky gut syndrome.

Side Effects

While generally safe, glutamine supplements can cause side effects in some people, including nausea, vomiting, stomach pain, gas, swelling, and muscle pain.

Interactions

Glutamine may interact with certain medications, including chemotherapy drugs, seizure medications, and lactulose. It is important to talk to your healthcare provider before starting any new supplement regimen.
