L-Glutamine shows great promise in scientific research for healing your gut. It was one leg of my ‘trinity,’ along with digestive enzymes and pascalite clay that formed the basis of the supplements I used to heal my gut. The other critical factor was massive doses of probiotics via food.
Glutamine is an amino acid that includes synthesizing protein and providing energy among its duties in the body. Multiple studies have shown it speeds healing and reduces healing time after intestinal surgery (another study). It specifically targets healing intestinal permeability and healing/preventing infection. It is being studied for its ability to help cancer patients heal from both the cancer itself and the side effects of conventional cancer treatment. It also benefits the kidneys, but should be avoided if you have Reyes Syndrome, kidney problems or cirrhosis of the liver. Some medical professionals recommend not supplementing with glutamine if you have any liver problems.
