What this could mean

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

Active substance: postbiotics (lactic acid bacteria byproducts)
What this could lead to: If it works, this could point toward a simple dietary supplement to help ease ADHD symptoms like mood and sleep problems in children.
What could go wrong: This is a small, early-stage open-label study with no placebo group, so results may be biased. It also only lasts 8 weeks, so long-term effects are unknown.
