L-Glutamine is an amino acid, one of the building blocks of protein that are linked together by peptide bonds in specific chemical arrangements to form proteins. It is found in both plant and animal proteins and is available in a variety of supplemental forms.

L-Glutamine helps the body maintain the proper acid/alkaline balance.

L-Glutamine helps promote a healthy digestive tract, making it one of the most important nutrients for gastrointestinal health.

L-Glutamine increases the amount of GABA, which is needed to sustain proper brain function and mental activity.

L-Glutamine rapidly facilitates healing and restores the health of mucous membranes inside the colon (large intestine). Just 1.6 grams per day, is used to treat peptic ulcers. Research shows that l-glutamine supplementation reduces stomach inflammation caused by chemotherapy and can be useful in treating diarrhea.

The body cannot synthesize enough glutamine to heal wounds, preserve lean tissue and nourish the immune system following surgery or physical stress.

L-Glutamine supplementation can normalize the amino acid levels, speeds healing, and improves overall surgical recovery. The primary source of energy for the immune system is l-glutamine. One of the reasons that cancer patients lose lean tissue and muscle mass is because of a depletion of l-glutamine.

Chemotherapy's toxic side effects can be shielded from the liver, animal studies show, and might strengthen the cancer-killing ability of certain chemotherapeutic drugs with l-glutamine supplementation.

When our T cell reserve is low, a standard measurement of immune activity, the cells, called macrophages, lose strength. But when l-glutamine is administered the immune system responds.

L-Glutamine is an essential treatment for AIDS or viral chronic fatigue syndrome.

L-Glutamine can inhibit fatty buildups inside the liver and aid treatment of cirrhosis.

L-Glutamine has been used to curb the desire to drink alcohol.

Cravings for sugar can be alleviated by taking l-glutamine. The National Institute of Mental Health recognizes l-glutamine's influence on sugar cravings.

By preserving lean tissue, which contributes to burning off fat, the amino acid helps cleanse the body and liver of waste products that are created by fat metabolism. In this way, l-glutamine may help obese persons with weight loss. Weight lifters can benefit from l-glutamine supplementation because it assists in the repair and preservation of muscle tissue. Prolonged exercise causes microscopic injuries to the muscles and, for a long as two weeks after a workout, lowers body's l-glutamine stores.
