Summary

This study tests whether a daily probiotic supplement called Limosilactobacillus reuteri LM1063 can improve sleep in healthy adults who have poor sleep quality. Over 8 weeks, 80 participants will take either the probiotic or a placebo, and researchers will measure sleep using both sleep lab tests and questionnaires. The goal is to see if this probiotic can be a safe, natural option for better sleep.

What this could mean

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

Active substance: Limosilactobacillus reuteri LM1063 (a probiotic)
What this could lead to: If it works, this could point toward a natural, side-effect-free way to improve sleep quality in people with mild sleep issues.
What could go wrong: This is an early-stage trial with only 80 people, so results may not apply to everyone. The effect on sleep might be small or no better than a placebo.
