Licorice and DGL: which form for heartburn, dose, and cost

For heartburn or indigestion, the form that matters is DGL (deglycyrrhizinated licorice), typically about 380-760 mg chewed before meals. The reason is safety: regular licorice contains glycyrrhizin, which in meaningful amounts can raise blood pressure and lower potassium, while DGL has that compound removed. If you want licorice for your gut, confirm the label says DGL.

The distinction that matters most

Licorice supplements come in two forms that look similar but behave very differently, and confusing them is the main risk here.

• Regular licorice contains glycyrrhizin. In meaningful amounts, and especially with prolonged use, glycyrrhizin can raise blood pressure and lower potassium, which can be dangerous for some people.
• DGL (deglycyrrhizinated licorice) has had the glycyrrhizin removed. That is what makes it far safer for regular use, and it is the form typically chosen for heartburn and indigestion.

So the first thing to check on any licorice product you plan to take regularly for your gut is whether it is DGL. If the label does not say so, assume it still contains glycyrrhizin.

Why DGL is the gut-symptom form

The traditional use of DGL is for heartburn and indigestion. The idea is that it supports the protective lining of the stomach and esophagus without carrying the blood-pressure risk of glycyrrhizin.

Two honest caveats:

• The evidence is limited and largely traditional, so DGL is better treated as worth trying than as a proven treatment.
• It does not replace evaluation of persistent or severe symptoms, which deserve a clinician's attention rather than self-treatment. Not medical advice.

The DGL dose for heartburn

A common approach is about 380-760 mg of DGL chewed before meals. Chewable tablets are the usual format, and taking it before eating is the traditional timing.

Practical notes:

• Start at the low end and follow the product label rather than stacking doses.
• Chewable forms are the typical delivery, since the traditional use involves contact with the upper digestive tract.
• If symptoms are frequent, severe, or not improving, that is a reason to see a clinician, not to keep escalating a supplement. Not medical advice.

The safety line on regular licorice

This is the part to take seriously. Regular, glycyrrhizin-containing licorice is not the same as DGL, and it should be avoided by several groups:

• People with high blood pressure.
• People with heart or kidney disease.
• People who are pregnant.

The concern is that glycyrrhizin can raise blood pressure and lower potassium, and prolonged use makes this worse. This applies to licorice supplements, licorice teas, and licorice candy made with real licorice extract. If you fall into any of those groups, or you are unsure, choose DGL or skip it and ask a clinician. Not medical advice.

What to look for on the label

• The word DGL or deglycyrrhizinated if you want it for daily gut use.
• A clear milligram amount of DGL per serving, not a vague blend.
• A chewable format if you are using it the traditional way, before meals.

How to buy DGL by cost per dose

Once you have confirmed it is the right form, the value question is straightforward.

• Confirm it is DGL if the purpose is daily heartburn or indigestion support.
• Note the milligrams of DGL per serving.
• Divide the total price by the number of servings in the bottle to get cost per dose, so a high-count bottle of low-dose tablets does not look cheaper than it really is.

Compare current prices per dose on /nutrients/licorice, see the best current value picks on /best/licorice, and read exactly how we calculate cost per dose on /methodology.

Buy the DGL product that hits your target dose at the lowest cost per dose, and if you have high blood pressure, heart or kidney disease, or you are pregnant, steer clear of regular glycyrrhizin-containing licorice.
