Deglycyrrhizinated licorice, commonly known as DGL, is a popular herbal supplement derived from the licorice root, Glycyrrhiza glabra. This specific form is processed to remove glycyrrhizin, the compound responsible for potential side effects such as elevated blood pressure, making it a safer option for long-term consumption. DGL is frequently sought out for its ability to support the digestive system, particularly the mucosal lining of the stomach and esophagus.
Identifying Available Forms of DGL
DGL is primarily concentrated around forms that maximize contact with the mouth and throat. The most common and often recommended format is the chewable tablet, typically containing 380 to 400 milligrams of DGL extract per piece. This chewable delivery is specifically designed to mix the active compounds with saliva, which is thought to be necessary for the supplement to promote the natural protective barrier in the upper digestive tract.
DGL is also available in standard capsule form, which is swallowed whole. While capsules are convenient, they bypass the necessary step of mixing with saliva, which may reduce the compound’s effectiveness for supporting the esophageal lining. Beyond tablets and capsules, consumers can sometimes find DGL in powder form, which can be mixed into liquids, or as chewable gels and lozenges.
Retail Locations and Online Platforms
Acquiring DGL is generally simple, as it is stocked by a wide range of both physical and digital retailers. Major national pharmacy chains, such as Walgreens and CVS, often carry DGL supplements, usually located in the herbal or digestive health aisles. Checking the inventory of a specific store online before visiting is often a time-saver.
Specialized health food and vitamin retailers, including The Vitamin Shoppe and GNC, reliably stock a broader selection of DGL brands and product formats. Larger grocery stores with extensive wellness sections, such as Whole Foods or Sprouts, are also reliable sources for this supplement. These physical locations allow consumers to immediately inspect the label for ingredients and dosage information.
For the widest selection and best price comparison, online platforms provide an excellent alternative. Major e-commerce sites like Amazon and Walmart feature dozens of different DGL products from various manufacturers. Direct-to-consumer websites for established supplement brands also offer DGL, frequently guaranteeing the freshest stock and providing detailed quality reports. Online shopping offers the convenience of reading customer reviews and accessing specialized formulas that might not be available in local stores.
Selecting a Quality Supplement
Making an informed choice requires a close inspection of the product label to ensure you are purchasing a quality supplement. The most important factor is confirming the supplement is truly deglycyrrhizinized, meaning the glycyrrhizin content has been reduced to less than 0.5 percent. Look for a clear statement on the label confirming the removal or low concentration of this compound.
Consumers should also verify the dosage of DGL extract per serving, as clinical studies use doses around 380 to 400 milligrams per chewable tablet. For chewable varieties, examine the “Other Ingredients” section for unwanted sweeteners or fillers, such as excessive sugar or artificial ingredients, which can be included to mask the strong licorice flavor. Finally, seek out brands that voluntarily engage in third-party testing for contaminants, such as heavy metals or microbial impurities. Seals from organizations like NSF International or U.S. Pharmacopeia (USP) indicate that an independent body has verified the product’s contents and quality standards.
