Summary

This small pilot study will test whether a synbiotic supplement (a mix of probiotics and plant extracts) can improve gut symptoms like bloating, pain, and irregular bowel habits in adults with Irritable Bowel Syndrome (IBS). Eight participants will take the supplement daily for 8 weeks, and researchers will track symptom changes and gut bacteria through stool samples and blood tests. The goal is to see if this natural approach can offer relief without medication.
