Probiotic shows promise for IBS and anxiety in new trial
NCT ID NCT07656623
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether adding a probiotic called Ecologic Barrier to standard treatment helps adults with irritable bowel syndrome (IBS) who also have stomach issues and anxiety, depression, or stress. Sixty participants will receive either standard care or standard care plus the probiotic for two months. Researchers will track IBS severity, mood changes, and side effects over 12 weeks.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Ecologic Barrier (multispecies probiotic mixture)
- What this could lead to
- If it works, this could point toward a simple, safe supplement to reduce IBS symptoms and related anxiety or depression.
- What could go wrong
- This is a small, early-phase trial with only 60 people. The probiotic may not outperform standard treatment, and results may not apply to everyone with IBS.
