Summary

This study tested whether a supplement containing curcumin, green tea, and vitamin D could help control symptoms in people with diarrhea-predominant irritable bowel syndrome (IBS-D). 78 adults with IBS-D took either the supplement or a placebo for 4 weeks, followed by 4 weeks where everyone got the supplement. The main goal was to see if symptoms like belly pain and bloating improved more with the supplement than with placebo.
