Gut check: can probiotics tame IBD in kids?
NCT ID NCT07533890
First seen Jun 27, 2026 · Last updated Jul 01, 2026 · Updated 2 times
Summary
This study looks at whether taking a mix of probiotics (good bacteria) can change the gut microbiome of children and teens aged 5-18 with inflammatory bowel disease (IBD). About 40 participants will be randomly assigned to take probiotics or a placebo, then switch after a period. The goal is to see if probiotics can improve gut health and reduce disease activity, but this is an early-stage trial focused on understanding how the microbiome responds.
