Summary

This study tests whether a daily probiotic supplement can improve the balance of gut bacteria in children aged 3 to 7 who have autism and digestive issues like constipation or stomach pain. Over 6 months, 60 children will receive either the probiotic or a placebo. The main goal is to see if the probiotic helps restore a healthy 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: probiotic supplement
What this could lead to: If it works, this could point toward a way to improve gut health and possibly ease digestive symptoms in children with autism.
What could go wrong: This is a small, early-stage trial with only 60 children. It focuses on gut bacteria changes, not on core autism symptoms, so benefits may be limited to digestion.
