Daily consumption of Lactobacillus gasseri CP2305 improves quality of sleep in adults - A systematic literature review and meta-analysis.

Based on existing evidence, the relationship between L. gasseri CP2305 and enhanced sleep quality is plausible, however further investigations are required to confirm the mechanisms of actions for this effect.
