Source Naturals Glutamine Comfort™ supports a healthy gut barrier by providing nourishment for the mucosal cells that form the gastrointestinal lining and are responsible for healthy permeability. Preliminary research has shown that glutamine and deglycyrrhizinated licorice (DGL) may support healthy intestinal mucosa. And, preliminary in vitro research on human colonic epithelial cells has shown that aloe vera may have antioxidant effects in the gut. Aloe vera has been used traditionally for centuries in Ayurvedic and Chinese medicines for digestive and intestinal support.*
