Condition
Indigestion
Indigestion, or dyspepsia, is discomfort in the upper abdomen during or after eating, with causes that range from stomach acid to slow emptying. Ginger and artichoke leaf extract have the strongest evidence, rated moderate, but the findings available are for astaxanthin, where one trial of 132 people found mixed results on reflux symptoms. So the picture is unsettled: astaxanthin's evidence is limited, and no trial results were available for ginger or artichoke.
