Deglycyrrhizinated Licorice (DGL)

Botanical Extract

DGL is licorice extract processed to reduce, not necessarily eliminate, glycyrrhizin. Products differ in remaining glycyrrhizin and other flavonoids; results for a standardized branded extract do not transfer to every chewable, powder, or capsule.

Pharmacokinetic model

A route-level PK model for deglycyrrhizinated licorice (dgl) is being prepared from published data. Dosing references, studies, and documented interactions are below; the app catalog is updated as models are validated.
