Evidence Map

What The Sources Report

• Each of these can have one of three scores of low, unclear, or high risk of bias. [Amini Sepide (2026); evidence level 1]
• Numerous neurological conditions, including multiple sclerosis, mood and anxiety disorders, Alzheimer's disease, Parkinson's disease, and migraines, have been associated with dysfunction of the gut-brain axis. [Gamil Noha M. (2025); evidence level 3]
• Gut dysbiosis also affects extra-neural pathways: (1) gut-liver axis-microbiota-derived LPS worsens hepatic inflammation, raising CRP and fibrinogen associated with migraine chronification (Bui et al.; Naghipour et al.; Vakilpour et al.) (2) gut-heart axis-SCFAs modulate autonomic tone, reducing the risk of cardiac arrhythmia in migraine sufferers (Amini-Salehi et al.). [Gamil Noha M. (2025); 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 vitamin B2 supplementation migraine 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.
