Deglycyrrhizinated licorice, commonly known as DGL, is a modified extract from the licorice plant, Glycyrrhiza glabra. This supplement is widely used to support the body’s natural digestive processes and soothe the gastrointestinal tract. DGL has gained attention as a gentler alternative to whole licorice root, which has certain side effects. This prompts questions about its safety profile, particularly the possibility of causing constipation.
How DGL Supports Digestive Health
DGL is prized for its unique action on the mucosal lining of the digestive system. It works primarily by stimulating the production and secretion of mucin, a protective substance that forms a gel-like barrier over the stomach and esophageal walls. This enhanced mucosal layer helps to defend against damage from stomach acid and other irritants. The compounds within DGL, including various flavonoids, support the integrity of the stomach lining rather than neutralizing acid directly. By promoting the regeneration of mucosal cells, DGL helps the body’s natural healing processes and demonstrates mild antispasmodic properties, which may help relax the intestinal wall and ease general indigestion discomfort.
Direct Answer to Constipation Concerns
Constipation is generally not a recognized side effect of DGL consumption. DGL’s function in promoting a soothed and healthy digestive environment suggests it should support regular bowel movements. The supplement itself is intended to support the digestive tract, and it is not known to create blockages or slow down intestinal motility.
If a person experiences constipation while taking DGL, the cause is likely related to external factors or other ingredients in the supplement. Dehydration or dietary changes often contribute to sluggish bowel movements. Some DGL formulations contain filler ingredients, such as calcium carbonate, which is known to cause constipation in some individuals.
DGL Versus Whole Licorice Root
The critical difference between DGL and whole licorice root lies in the removal of a compound called glycyrrhizin. Glycyrrhizin is naturally present in licorice root and is responsible for its characteristic sweet flavor. This compound is also the source of the most concerning side effects associated with whole licorice consumption.
Glycyrrhizin can affect the body’s hormone balance, potentially leading to elevated blood pressure, fluid retention, and a decrease in potassium levels, a condition known as hypokalemia. DGL, which stands for Deglycyrrhizinated Licorice, has been specially processed to remove most of the glycyrrhizin, typically leaving less than 3% remaining. This processing makes DGL a much safer option for prolonged use, as it avoids the serious cardiovascular and electrolyte-related side effects linked to whole licorice.
Safe Consumption and Potential Side Effects
For optimal effect, DGL is often recommended in chewable tablet form, as mixing it with saliva is thought to activate its beneficial compounds before they reach the stomach. A common practice is to take the supplement approximately 15 to 20 minutes before a meal to allow the protective mucosal stimulation to occur prior to digestion. Typical dosages for digestive support often range from 300 to 400 milligrams taken before meals.
DGL is considered safe for most people when taken as directed because the problematic glycyrrhizin has been removed. Rare, minor adverse reactions may include mild gas, temporary bloating, or occasional loose stools. It is always advisable to consult a healthcare provider before beginning any new supplement, especially if managing pre-existing health conditions or taking other medications.
