coenzyme Q10 prevents migraine
In plain terms: Can CoQ10 prevent migraines?
Part of: 🧪 coenzyme Q10
Maybe modestly in adults—one small positive trial leans supportive, but a pediatric trial was null and the overall evidence is thin.

How the studies fall
What the evidence shows
CoQ10 for migraine prophylaxis leans supportive but is far from settled: a small adult RCT (n=42) found it superior to placebo (50%-responder 48% vs 14%, NNT 3) and a dose-response supplement meta-analysis shows a preventive signal — yet a double-blind pediatric/adolescent crossover RCT found no separation from placebo, and vitamin/mineral reviews judge the evidence limited.

Disagree, or know a study we missed?
We grade by evidence, not opinions. The way to weigh in is to point us to a study we haven't cited (check the evidence table above first), or to flag a problem with one we have. Every submission is reviewed; if it holds up, the grade updates and shows in Science Changes Its Mind.
Opens a short form. You'll sign in with Google so submissions are tied to a real account — we don't display your identity, and we only accept a link we can verify (PubMed, DOI, ClinicalTrials.gov).
