The Active Ingredient Is: L-Glutamine

L-Glutamine is an amino acid that helps cellular function inside the gut lining. This stuff helps nourish intestinal cells and is linked with keeping barrier integrity in digestive tissues.

This formula also includes other ingredients like prebiotics, probiotics, and antioxidants which help support gut health and overall intestinal comfort.

What Does L-Glutamine Do?

L-Glutamine helps with gut barrier function and mucosal integrity, a role you’ll hear about in intestinal health talks. Dr. Rao from the University of Toronto and colleagues have highlighted its relevance to gut barrier support in human studies.

Besides barrier support, the nutrient participates in normal cell metabolism and energy supply inside the intestinal lining, contributing to overall gastrointestinal function, as nutrition science notes.
