L-Glutamine: What Is It and How Is It Beneficial?

L-Glutamine: What Is It and How Is It Beneficial?

I was just recommending that a patient use L-glutamine (GSH) the other day, so I decided that I should write a little blurb about it and its many benefits.

L-glutamine is an important amino acid (which are building blocks to protein) that is very influential when it comes to the gastrointestinal (GI) system because of its role as a large energy source for and its ability to heal the cells of the GI tract.

Food Sources

  • Cabbage, particularly cabbage juice, is a great dietary source of L-glutamine. 


  • Source of Energy: An essential and preferred source of energy for enterocytes of the gastrointestinal tract.
  • Tissue Repair: A critical component for tissue repair, especially in the intestines, and aid in the restoration of normal permeability.
  • Co-Factor to Other Nutrients: A co-factor for the synthesis of vitamin B3 (niacin) and the metabolism of arginine and uric acid.


  • Alcoholism: May decrease cravings for alcohol.
  • Inflammatory Bowel Disease: To help maintain weight and heal the gut mucosa.
  • Peptic Ulcers: To heal the gut mucosa.
  • Total Parenteral Nutrition (TPN): A vital component of TPN in order to prevent or treat atrophy (blunting) of the intestinal villi.
