NCT ID NCT06568588
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether a probiotic called Saccharomyces boulardii can improve digestive health, immune function, nutrition, and behavior in children aged 5 to 12 with autism and a history of gut problems. Sixty-six children in Ecuador will take the probiotic for 4 months and then stop for 4 months, with researchers tracking changes through stool, blood, and urine samples, as well as behavior and intelligence tests. The goal is to see if this simple supplement can make a real difference in their daily lives.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Saccharomyces boulardii (a probiotic)
What this could lead to
If it works, this could point toward a simple probiotic supplement to ease digestive symptoms and possibly improve behavior in children with autism.
What could go wrong
This is a small Phase 2 trial with only 66 children, so results may not apply to everyone. The probiotic may not cause meaningful changes, and any benefits might be modest.
