Multi-strain Lactobacillus and Bifidobacterium probiotic formulations improve sleep quality in elite athletes
Probiotic interventions with multi-strain Lactobacillus and Bifidobacterium formulations enhanced sleep quality in elite athletes, as reported in small-scale randomized controlled trials and a controlled non-randomized study. The evidence is preliminary, with improvements noted in self-reported sleep quality.

How It Works
The proposed biological pathway:
- ▸Probiotics modulate gut microbiota composition
- ▸Gut-brain axis regulates neurotransmitter production
- ▸Gut-brain axis controls circadian rhythms
- ▸Improved sleep quality
Who Might Benefit
Evidence fit by population:
- ▸Elite athletes
Recommended Dose
N/A
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Small-scale trials with limited sample sizes
- ▸One study was non-randomized, reducing causal inference
- ▸Self-reported sleep quality may be subjective
Frequently Asked Questions
What specific probiotic strains were used?▼
The abstract mentions multi-strain formulations of Lactobacillus and Bifidobacterium, but does not specify exact strains.
How was sleep quality measured?▼
Sleep quality was assessed via self-report, not objective measures like polysomnography.
Are these findings applicable to non-elite athletes?▼
The study focused on elite athletes, so generalizability to other populations is uncertain.
What is the proposed mechanism for sleep improvement?▼
The gut-brain axis is proposed to modulate sleep by regulating neurotransmitter production and controlling circadian rhythms.
