Three things to remember
- Digestive benefits from licorice alone remain uncertain.
- DGL should not be assumed equivalent to ordinary glycyrrhizin-containing licorice.
- Verify DGL identity and any residual glycyrrhizin specification rather than relying on flavour or colour.
Digestive claims need a preparation match
NCCIH finds insufficient high-quality evidence for licorice across health conditions and uncertainty about digestive symptoms from licorice alone. Research on a multi-herb formula does not prove that DGL was responsible for the outcome.
Claims about soothing the stomach should not become promises to heal ulcers, eradicate an infection or replace prescribed treatment. Mouth-rinse research also does not establish that a swallowed capsule has the same effects in the stomach.
DGL versus ordinary licorice
The label should explicitly identify DGL rather than only Glycyrrhiza root or a general licorice extract. Check the full ingredient list: a blend can contain DGL alongside ordinary licorice or other herbs.
Chewable tablets, capsules and liquid formulas differ in use and additional ingredients. For a chewable, the number of pieces, sweeteners and flavouring are useful comparison details. A licorice taste does not establish the presence, absence or quantity of glycyrrhizin.
What the milligram number does not tell you
There is no established daily nutritional requirement for DGL. The weight of a DGL extract is not a glycyrrhizin measurement. If a manufacturer supplies a residual percentage, it must be attached to the actual extract quantity and a clear test basis.
For a hypothetical 400 mg extract with a specified maximum residual content of 1%, the arithmetic gives a maximum of 4 mg for that constituent. This illustrates a specification; it does not establish a safe threshold or endorse that product.
The distinction has real safety implications
Glycyrrhizin-containing licorice can cause serious heart-rhythm problems; people with hypertension or heart or kidney conditions may be especially vulnerable. NCCIH notes that glycyrrhizin-free oral products might be safe for up to four months, which is not a guarantee for every product or long-term use.
Licorice interactions with corticosteroids have been reported. DGL identity does not automatically resolve pregnancy, breastfeeding or medication questions, especially when the formulation contains other ingredients.
A hypothetical chewable comparison
A ₹800 pack of 100 tablets with two tablets per label serving gives 50 servings at ₹16. A ₹600 pack of 60 tablets with the same serving size gives 30 servings at ₹20.
Compare only after checking that both specify DGL and comparable quantities. A cheaper ordinary licorice tablet is not a like-for-like substitute. A bottle’s tablet count can overstate how long it lasts when several tablets make a serving.
The useful evidence trail
Look for botanical identity, DGL status, a declared extract amount, any glycyrrhizin specification and a complete ingredient panel. Batch testing is most useful when it identifies what was measured rather than displaying an unexplained quality logo.
A good listing keeps uncertainty visible: unclear residual content stays unclear, and a traditional digestive claim stays distinct from clinical proof. More extract does not automatically mean greater benefit or a suitable choice for persistent symptoms.
Common questions
Is ordinary licorice a substitute for DGL?
No. Removing glycyrrhizin changes a clinically important part of the preparation. The names should not be treated as interchangeable.
Does DGL mean completely risk-free?
No. Product identity, residual specifications, additional ingredients, medicines and limited long-term evidence still matter.
Take the knowledge with you.
Compare the same form, active amount and intended use before comparing price. India and International listings have separate filters; some categories may have no listings in one market. Listings do not establish local stock or a need for a supplement. Shopping disclosures appear on product pages.
