Probiotic VSL#3 may tweak bile acids in IBD patients
NCT ID NCT01765439
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether the probiotic VSL#3 can change how bile acids work in people with Crohn's disease or ulcerative colitis. About 79 participants will take two sachets of VSL#3 daily for six weeks. Researchers will measure bile acid levels in blood and stool to see if the probiotic helps manage the disease.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- VSL#3 probiotic (a mix of live bacteria)
- What this could lead to
- If it works, this could point toward a way to improve bile acid balance and reduce symptoms in people with inflammatory bowel disease.
- What could go wrong
- This is a small, early-stage study with no phase, so results may not lead to a proven treatment. The probiotic may not change bile acid levels as hoped.
