DGL comes from licorice root, but it is not compositionally the same as regular licorice root. DGL means deglycyrrhizinated licorice: manufacturers remove most glycyrrhizin, the constituent linked with potassium, blood-pressure, fluid-balance, and heart-rhythm concerns. Licorice tea, whole-root capsules, candy, flavoring, and DGL should not be treated as interchangeable products.
How did we evaluate DGL and licorice root?
We evaluated ingredient identity, glycyrrhizin removal, serving disclosure, format, public product labels, government safety guidance, and human clinical research. The National Center for Complementary and Integrative Health received more weight than retailer summaries, traditional-use claims, or customer reviews. Randomized studies of standardized deglycyrrhizinated licorice extracts were treated as extract-specific evidence rather than proof for every DGL bottle. We excluded claims that DGL cures reflux, ulcers, or other conditions because supplement evidence and regulatory framing do not support product-wide treatment promises. We also separated whole licorice root, DGL extract, candy, tea, and anise flavoring because each can have different constituents and exposure. We reviewed cited pages on August 11, 2026, and favored reproducible facts over promotional framing alone for publication. Public labels can change, and “deglycyrrhizinated” does not establish zero glycyrrhizin unless a specification states that result.
What does DGL mean on a supplement label?
DGL means deglycyrrhizinated licorice, usually an extract of Glycyrrhiza glabra root processed to remove most glycyrrhizin. The three-letter term describes the extract type, not a dose, delivery format, brand, or clinical effect. A complete label should identify DGL or deglycyrrhizinated licorice, milligrams per serving, serving size, other ingredients, storage, and directions. A bottle labeled only “licorice root” does not establish that glycyrrhizin was reduced. “Licorice flavor” may come from anise oil and may contain no licorice root at all, while black licorice candy can vary by manufacturer and country. The NCCIH licorice overview confirms that many U.S. licorice-flavored products use anise oil. Expiration dates, lot identity, and manufacturer testing add further traceability for routine buyers too. The safest comparison starts with the exact Supplement Facts panel rather than flavor, color, or the word natural.
Why does removing glycyrrhizin matter?
Glycyrrhizin, also called glycyrrhizic acid, is a natural licorice constituent associated with the classic safety concerns of sustained or high whole-licorice exposure. Intestinal metabolism produces glycyrrhetinic acid, which can alter cortisol metabolism and contribute to sodium retention, potassium loss, higher blood pressure, edema, and abnormal heart rhythm. NCCIH reports that serious adverse effects can occur, especially with large amounts, long use, high salt intake, hypertension, or heart or kidney conditions. Deglycyrrhizination reduces this exposure lane; it does not turn every DGL formula into an identical or risk-free product. Different extracts retain different flavonoids, use different glycyrrhizin specifications, and add different sweeteners or binders for current consumers. Duration matters. A 2025 randomized trial used GutGard with glycyrrhizin specified at no more than 3% by weight, showing why a named extract specification matters more than a generic DGL claim.
How do DGL, regular licorice root, tea, and candy compare?
This article contains commercial links to Yuve products; Yuve earns revenue from product sales, but that relationship did not change the evidence standards used here. DGL, whole licorice root, herbal tea, candy, and flavoring differ by processing, dose transparency, glycyrrhizin exposure, and intended use. Whole-root products retain naturally occurring glycyrrhizin unless the label says otherwise. DGL products remove most glycyrrhizin but can use different residual specifications. Tea strength depends on the plant material, steeping method, and serving. Candy may contain real licorice extract, anise flavor, or both. No single form automatically inherits another form’s dose, evidence, purity, or safety profile either. The table compares ingredient identity and uncertainty rather than declaring every licorice-derived item equivalent. People with medication, blood-pressure, potassium, heart, kidney, or pregnancy concerns should review any licorice exposure with a qualified clinician.
| Form | What it contains | Best for | Main limitation |
|---|---|---|---|
| DGL supplement | Deglycyrrhizinated licorice extract | Glycyrrhizin-conscious licorice routine | Residual specification and extract can vary |
| Regular licorice-root supplement | Whole or concentrated root constituents | Traditional whole-herb use under informed guidance | Glycyrrhizin and interaction concerns |
| Licorice tea | Variable water extract from plant material | Occasional beverage use | Dose and glycyrrhizin exposure are hard to quantify |
| Black licorice candy or flavoring | May use licorice extract, anise oil, or both | Food flavor | Ingredient identity and cumulative intake vary |
Which form is best for each use case?
Best for reducing glycyrrhizin uncertainty: a DGL product that clearly states deglycyrrhizinated licorice and publishes a residual glycyrrhizin specification. Best for a chewable pre-meal routine: a DGL chewable with transparent milligrams, serving size, and other ingredients. Best for avoiding sweeteners or strong licorice taste: a DGL capsule whose panel fits the user’s needs. Best for traditional whole-root use: regular licorice only when glycyrrhizin exposure, medicines, blood pressure, potassium, and duration have been reviewed. Best for occasional flavor: a food product whose ingredient list clarifies whether it uses licorice extract or anise. Best for persistent or changing upper-digestive symptoms: medical evaluation, because a supplement choice should not delay assessment. Best for uncertain symptoms: professional review before any new supplement could further complicate the clinical picture. No format earns a universal recommendation from the word “licorice” alone today.
Which Yuve DGL product meets the label criteria?
Yuve DGL Licorice Chewables list 400 milligrams of DGL licorice-root extract plus 100 milligrams of glycine per two-chewable serving. The current public panel lists xylitol, microcrystalline cellulose, stearic acid, natural licorice flavor, silica, and magnesium stearate as other ingredients. The page identifies the extract as deglycyrrhizinated, which is the key distinction from regular licorice root, but it does not establish that the formula is identical to GutGard used in published trials. Xylitol can also affect gastrointestinal tolerance for some people. The current page was reviewed on August 11, 2026, so verify any later label changes before purchase. Yuve’s digestion collection includes products with different jobs, so DGL should not be treated as interchangeable with probiotics, prebiotic fiber, lactase, or digestive enzymes. Choose by ingredient role, current label, and safety context rather than brand family.
What does human research say about DGL?
Human evidence is limited and extract-specific. A 2012 randomized, double-blind, placebo-controlled trial enrolled 50 adults and evaluated GutGard for 30 days; symptom scores improved compared with placebo, but the small sample and named extract limit generalization. A 2025 randomized placebo-controlled trial enrolled 200 adults and evaluated the same standardized extract for 28 days, reporting improvements in selected reflux-related symptom measures. These trials provide directional support for GutGard under the studied doses, populations, durations, and outcomes. Neither trial directly compared DGL with whole licorice root, tea, candy, or a Yuve product in practice at all. They do not prove that every DGL product performs the same way, that DGL replaces prescribed care, or that regular licorice root is equivalent. The strongest label-to-evidence match requires the same standardized extract and dose used in replicated human research.
What do people ask about DGL and licorice root?
Is DGL just another name for licorice root?
No. DGL is licorice-root extract processed to remove most glycyrrhizin. Regular licorice root retains naturally occurring glycyrrhizin unless the label documents removal. Format alone does not establish potency, purity, safety, or extract equivalence for consumers.
Does DGL contain zero glycyrrhizin?
Not necessarily. Deglycyrrhizination means substantial removal, but residual specifications vary. Check whether the manufacturer publishes a measurable limit.
Is black licorice candy the same as DGL?
No. Candy can contain whole licorice extract, anise flavor, or both, plus sugar and other ingredients. It is not a standardized DGL supplement.
Is licorice tea deglycyrrhizinated?
Usually not unless the package explicitly says so. Tea made from ordinary licorice root can deliver glycyrrhizin in an amount that varies with dose and steeping.
Can DGL still have side effects?
Yes. DGL can contain residual glycyrrhizin and other active constituents, while sweeteners or binders can affect tolerance. Medicines and health conditions also matter.
How long can DGL be used?
NCCIH says glycyrrhizin-free oral licorice products might be safe for up to four months. That cautious statement is not proof of indefinite safety or suitability for every formula.
What is the bottom line on DGL versus licorice root?
DGL is derived from licorice root but is processed to remove most glycyrrhizin, so DGL and regular licorice root are not interchangeable. That processing reduces the constituent responsible for many blood-pressure, potassium, fluid-balance, and rhythm concerns, but it does not make every DGL extract identical or risk-free. Check the label for “deglycyrrhizinated licorice,” milligrams per serving, residual glycyrrhizin specification, other ingredients, timing, and duration. Yuve DGL Licorice Chewables provide a transparent 400-milligram chewable serving but should not inherit evidence from a different standardized extract automatically. Licorice tea, candy, anise flavoring, whole-root capsules, and DGL belong in separate comparison lanes. A transparent label reduces uncertainty, but symptoms and interaction risk still require judgment over time during everyday routine use. When medicines, pregnancy, blood pressure, potassium, heart, or kidney concerns apply, get individualized guidance before use.
