Glycyrrhiza glabra
Evidence Level
Moderate
1 Clinical Trial
3 Documented Benefits
3/5 Evidence Score

GutGard® is a flavonoid-rich licorice (Glycyrrhiza glabra) root extract from Natural Remedies, processed to remove most glycyrrhizin (the compound that can raise blood pressure). This makes it a gentler licorice for digestive use, and it is studied for easing reflux, indigestion, and supporting the stomach lining.

Studied Dose Around 150 mg per day.
Active Compound Glycyrrhiza glabra root extract standardized to licorice flavonoids and largely free of glycyrrhizin.

Benefits

Reflux and indigestion

In a clinical study, GutGard supported relief of gastroesophageal reflux and indigestion symptoms, easing heartburn and upper-digestive discomfort.

Stomach lining support

Licorice flavonoids support the protective mucus lining of the stomach, helping defend it against irritation.

H. pylori balance

Licorice extracts are studied for discouraging the H. pylori bacteria linked to gastritis and ulcers, supporting a healthier stomach environment.

Mechanism of action

1

Mucosal protection

Licorice flavonoids stimulate protective mucus and support the integrity of the stomach and esophageal lining.

2

Glycyrrhizin removed

Removing glycyrrhizin keeps the digestive benefits while avoiding the blood-pressure and potassium effects of whole licorice.
