Probiotic Sleep Meta-AnalysisThe microbiota-gut-brain axis suggests probiotics and synbiotics could modulate sleep, but evidence in exercised populations is limited.1Salehi Asl M (2026)The effect of probiotic and synbiotic supplementation on sleep parameters in exercised population: a systematic review and synthesis without meta-analysis (SWiM) of randomized controlled trials.
Probiotic Sleep Meta-AnalysisData extraction, risk of bias assessment (RoB 2), and narrative synthesis followed SWiM guidelines.1Salehi Asl M (2026)The effect of probiotic and synbiotic supplementation on sleep parameters in exercised population: a systematic review and synthesis without meta-analysis (SWiM) of randomized controlled trials.
Probiotic Sleep Meta-AnalysisNine of twelve primary sleep outcomes favored supplementation, with significant effects for probiotics (combined p p Conclusion Probiotic and synbiotic supplementation may improve sleep in exercised populations, especially perceived quality and latency.1Salehi Asl M (2026)The effect of probiotic and synbiotic supplementation on sleep parameters in exercised population: a systematic review and synthesis without meta-analysis (SWiM) of randomized controlled trials.
Probiotic Sleep Meta-AnalysisBackground Sleep is crucial for recovery and optimal performance in athletes; however, poor sleep is common during periods of intensive training or competition.1Salehi Asl M (2026)The effect of probiotic and synbiotic supplementation on sleep parameters in exercised population: a systematic review and synthesis without meta-analysis (SWiM) of randomized controlled trials.
Probiotic Sleep Meta-AnalysisData from the included studies were extracted, and their risk of bias was assessed.1Ren T (2026)Association between probiotic intervention and sleep quality in the general adult population: a systematic review and meta-analysis.
Probiotic Sleep Meta-AnalysisThe meta-analysis revealed that probiotic supplementation significantly reduced PSQI scores compared to the control group (mean difference [MD] = -0.59, 95% confidence interval [CI]: -0.83 to -0.35, p I 2 = 46%).1Ren T (2026)Association between probiotic intervention and sleep quality in the general adult population: a systematic review and meta-analysis.
Probiotic Sleep Meta-AnalysisConclusion Probiotic supplementation was associated with a modest but statistically significant improvement in sleep quality among adults, regardless of their baseline sleep status (ranging from healthy to suboptimal), as measured by PSQI and ISI scores.1Ren T (2026)Association between probiotic intervention and sleep quality in the general adult population: a systematic review and meta-analysis.
Probiotic Sleep Meta-AnalysisBackground The discovery of the microbiota-gut-brain axis provides a theoretical basis for using probiotic supplementation to improve sleep health.1Ren T (2026)Association between probiotic intervention and sleep quality in the general adult population: a systematic review and meta-analysis.
