DGL Licorice Root: The Ancient Remedy That Modern Science Is Finally Validating

Licorice root has been used medicinally for over 4,000 years. Ancient Egyptian, Chinese, and Greek physicians all documented its use for digestive complaints. For most of that history, the mechanism was a mystery. Today, modern research is confirming what traditional practitioners observed: licorice root, specifically in its deglycyrrhizinated (DGL) form, has powerful gut-soothing and lining-protective properties.

Why DGL, Not Regular Licorice

Regular licorice root contains glycyrrhizin, a compound that can cause serious side effects including elevated blood pressure, potassium depletion, and fluid retention. DGL removes the glycyrrhizin while preserving the beneficial compounds that support gut health. This makes it safe for daily long-term use without the cardiovascular risks associated with whole licorice root.

How DGL Supports Gut Healing

DGL works through two primary mechanisms. First, it stimulates the production and secretion of mucus in the digestive tract. This mucus layer is the gut lining’s first line of defense — it physically shields the epithelial cells from stomach acid, digestive enzymes, and irritants. When the mucus layer is depleted (common in people with chronic gut issues), the lining is exposed and vulnerable. DGL helps rebuild this protective barrier.

Second, DGL has anti-inflammatory properties that calm the chronic low-grade inflammation characteristic of gut lining damage. By reducing inflammation at the lining surface, DGL creates conditions that allow epithelial cells to repair and tight junctions to strengthen.

Practical Usage

DGL is typically taken at 400mg per dose, either as a chewable tablet (which allows the DGL to coat the upper digestive tract) or as a capsule. Many practitioners recommend taking it 20 minutes before meals to allow the mucus-stimulating effects to prepare the digestive tract for food. DGL can be used as a standalone supplement for mild gut issues or as part of a comprehensive gut repair stack for more advanced cases.

DGL pairs exceptionally well with L-glutamine. While glutamine provides the fuel for cellular repair, DGL provides the protective coating that shields the repair process from ongoing damage. Together, they accelerate healing by simultaneously building up and defending the gut lining.
