First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times
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 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.
