# Inulin Sleep Randomized Trial: What the Evidence Says

## Quick Answer

Inulin Sleep Randomized Trial has 2 source documents in the current Migaku evidence database. The strongest available sources in this first pass are systematic review, so conclusions should be framed as evidence-aware guidance rather than medical advice.

## Key Takeaways

- This page is generated only from sources stored in the Migaku evidence knowledge base.
- Current evidence mix: 1 systematic review, 1 narrative review.
- Claims should be interpreted with the source type, study design, population, and publication date in mind.
- This article is educational and does not replace care from a qualified clinician.

## Evidence Map

| Source | Evidence type | Level | Date | Identifier |
| --- | --- | ---: | --- | --- |
| 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 | systematic review | 1 | 2026-05-25 | 10.1080/15502783.2026.2670564 |

## What The Sources Report

- A 2024 meta-analysis of randomised, placebo-controlled trials found that probiotics reduced Pittsburgh Sleep Quality Index (PSQI) scores at 4-6 and 8-16 weeks and delivered small but significant gains in sleep efficiency; effects on sleep duration and insomnia severity were less consistent, and risk-of-bias/potential publication bias were noted. [Salehi Asl Mina (2026); evidence level 1]
- 14 18 Evidence specific to exercise populations remains limited and heterogeneous. [Salehi Asl Mina (2026); evidence level 1]
- The regulatory classification of probiotics, however, is not uniform and may vary depending on their intended use, formulation, route of administration, and associated health claims. [Chong Shin-Yee (2026); evidence level 3]

## How To Read This Evidence

Evidence level 1 generally reflects systematic reviews or meta-analyses. Level 2 includes randomized trials, guidelines, or public-health guidance. Level 3 usually reflects observational or narrative-review evidence. Level 4 is weaker or early-stage evidence. The level is a sorting aid, not a final quality grade.

## Practical Interpretation

There is at least one systematic-review style source in the current set, so it deserves more weight than single-study evidence. For inulin sleep randomized trial, the next editorial step is to add more targeted sources and separate strong findings from early or indirect evidence.

## Limits Of This First Pass

This is a small-batch MVP article. It uses the first ingested sources for this topic and should be expanded with more targeted searches, license review, and human editorial checks before being treated as a definitive review.
