Quick Answer
Probiotic Sleep Randomized Trial has evidence relevant to strength of evidence and what the studies can or cannot prove, but conclusions should stay close to the cited sources. One representative finding is: The microbiota-gut-brain axis suggests probiotics and synbiotics could modulate sleep, but evidence in exercised populations is limited.
Key Takeaways
- 01The microbiota-gut-brain axis suggests probiotics and synbiotics could modulate sleep, but evidence in exercised populations is limited. [Salehi Asl M (2026)]
- 02Data extraction, risk of bias assessment (RoB 2), and narrative synthesis followed SWiM guidelines. [Salehi Asl M (2026)]
- 03Nine 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. [Salehi Asl M (2026)]
- 04Background Sleep is crucial for recovery and optimal performance in athletes; however, poor sleep is common during periods of intensive training or competition. [Salehi Asl M (2026)]
The current Migaku evidence database contains 2 reusable source documents for Probiotic Sleep Randomized Trial. This answer focuses on strength of evidence and what the studies can or cannot prove.

- Probiotic blend effectively alleviated symptoms of FC and improved physical well-being. [Park HG (2026); evidence level 2]
Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording.
