L-glutamine for gut health

Your gut lining comprises of cells that use l-glutamine as their main fuel source. It helps these cells repair and regenerate, especially after damage caused by stress, infection, inflammation, or medication. L-glutamine also helps maintain the integrity of the intestinal barrier, which prevents toxins and pathogens from entering your bloodstream.

By taking l-glutamine supplements or eating foods rich in l-glutamine, you can support your gut health in several ways. Here are some of the benefits of l-glutamine for your gut:

  • It reduces intestinal permeability, also known as leaky gut syndrome, which can cause bloating, gas, diarrhea, food sensitivities, and autoimmune disorders.
  • It protects against intestinal infections, such as H. pylori, which can cause ulcers and gastritis.
  • It enhances the production of mucin, a protective layer that coats your gut lining and helps prevent irritation and inflammation.
  • It modulates the immune response in your gut, which can help prevent or treat inflammatory bowel diseases, such as Crohn’s disease and ulcerative colitis.
  • It supports the growth of beneficial bacteria in your gut, which can improve your digestion, immunity, and mood.

As you can see, l-glutamine is more than just a muscle-building supplement. It is also a powerful ally for your gut health.
