DGL vs. Licorice Root: A Crucial Distinction
Many people confuse DGL with licorice root, which is the source plant from which DGL is derived. The key difference lies in the presence of glycyrrhizin, a compound naturally found in licorice root. While licorice root has been used for centuries in traditional medicine, high doses of glycyrrhizin are associated with serious side effects, including elevated blood pressure, low potassium levels, and fluid retention.
To create DGL, manufacturers specially process the licorice root to remove the glycyrrhizin, leaving behind other beneficial flavonoids and compounds. This makes DGL a much safer alternative for long-term use, especially for digestive issues, without the risk of these adverse effects. Therefore, the search for foods high in DGL is futile, as the substance is a product of human processing, not a naturally occurring dietary component.
Why DGL Supplements are Used for Digestive Health
Instead of searching for food sources, those interested in DGL's benefits should look to supplements. DGL is commonly recommended for soothing and protecting the gastrointestinal tract. Unlike antacids that simply neutralize stomach acid, DGL works by enhancing the body's own protective mechanisms.
The Mechanism of DGL
- Enhances Mucus Production: DGL stimulates the production of mucin, the protective mucus that lines the stomach and intestinal wall. This layer acts as a barrier, shielding the delicate tissues from stomach acid and other irritants.
- Increases Blood Supply: Research indicates that DGL can increase the blood supply to the lining of the digestive organs, promoting repair and healing of damaged tissues.
- Stimulates Cell Growth: It helps to increase the number of mucus-producing cells and the lifespan of intestinal cells, reinforcing the digestive lining's integrity.
Comparison Table: DGL vs. Licorice Root
| Feature | Deglycyrrhizinated Licorice (DGL) | Licorice Root (Whole) |
|---|---|---|
| Key Active Compounds | Flavonoids | Glycyrrhizin, Glycyrrhetinic Acid |
| Potential Side Effects | Minimal, safer for long-term use | Significant risk of elevated blood pressure, low potassium, fluid retention |
| Primary Therapeutic Use | Digestive support (ulcers, reflux, gastritis) | Traditional herbal remedy, flavoring agent |
| Availability | Primarily as supplements (chewables, capsules, etc.) | Teas, candy, traditional extracts, herbal formulas |
| Suitability for Long-Term Use | Considered safe under professional guidance | Caution advised, especially with high doses or pre-existing conditions |
Common Forms of DGL Supplements
DGL supplements come in various forms to suit different needs. Chewable tablets are particularly popular because they allow DGL to mix with saliva, which some believe enhances its soothing effect on the upper digestive tract. Other forms include:
- Chewable Tablets: These are often sweetened and flavored to make them more palatable. The act of chewing is believed to activate the compounds before they reach the stomach.
- Capsules and Tablets: For those who prefer a taste-free option, DGL is available in standard capsule form that can be taken with water.
- Powder: Some manufacturers offer DGL in a powder that can be mixed into water or other beverages.
- Liquid Extracts: A liquid form is also available, which offers a flexible dosage.
Precautions and Sourcing
While DGL is significantly safer than whole licorice root, it is always wise to consult a healthcare professional before starting any new supplement regimen, especially if you are pregnant, nursing, have a medical condition, or are taking other medications. To ensure you are getting a quality product, look for supplements from reputable manufacturers and be aware of ingredient lists that may include additional herbs like aloe vera or marshmallow root.
To find more details on DGL's properties and potential benefits, authoritative sources like the National Institutes of Health (NIH) offer extensive information on herbal supplements.
Conclusion
In summary, the notion of finding foods naturally high in DGL is based on a fundamental misunderstanding. DGL is not a food but a manufactured supplement derived from licorice root with the potentially problematic glycyrrhizin removed. Its value lies in its targeted use for supporting digestive health, leveraging the power of plant-based compounds in a safe, processed form. For anyone looking to use DGL, the correct approach is to seek out reputable supplements and follow appropriate dosage guidelines, rather than searching for non-existent dietary sources.
