How to take licorice root as a supplement
Peeled licorice root is available in dried and powdered forms and as capsules, tablets and liquid extracts. The safest dose for most adults to get the full health benefits is 1 to 5 grams of licorice daily containing 1 to 10 milligrams of the active ingredient glycyrrhizin, for 4 to 6 weeks.
Note that in large amounts and in people with hypertension or heart, kidney or lung disease, licorice that contains glycyrrhizin can cause adverse reactions. Choosing deglycyrrhizinated licorice (DGL)’licorice with the glycyrrhizin removed’can lower the risk of serious side effects.
