Creatine Sleep Latency Meta-analysis: What the Evidence Says

Quick Answer

Creatine Sleep Latency Meta-analysis 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 research article.
• 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

What The Sources Report

• Evidence on specific supplements suggests potential but limited benefit to dancers. [Vela-Andreu Marian (2026); evidence level 1]
• Vitamin D insufficiency has been associated with increased risk of musculoskeletal injury, and interventional studies in a small population of dancers suggest potential reductions in injury incidence and enhanced muscle function with supplementation, although dancer-specific evidence remains scarce. [Vela-Andreu Marian (2026); evidence level 1]
• Its production follows the light-dark cycle, resulting in an increased production at night and a decreased production during the day. [Mahdi Nourhène (2026); evidence level 4]
• Supplementation improved both sleep quantity and quality during the subsequent night and enhanced physical performance the following morning, including vertical and horizontal jumps (VJs, HJs) and handgrip strength (HG), and the five-jump test (5-JT) was improved. [Mahdi Nourhène (2026); evidence level 4]

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 creatine sleep latency meta-analysis, 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.
