Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting

Summary

This study tests whether taking a daily prebiotic supplement for 8 weeks can improve gut health and reduce inflammation in people with ulcerative colitis. Researchers will collect stool samples and track symptoms in 70 adults. The goal is to see if prebiotics can help manage the disease by changing the gut microbiome.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
prebiotic supplement
What this could lead to
If it works, this could point toward a simple dietary supplement to help manage ulcerative colitis symptoms and improve gut health.
What could go wrong
This is a small, early-stage study with only 70 participants, so results may not apply to everyone. The supplement may not reduce inflammation or symptoms significantly.
