coenzyme Q10 prevents migraine
In plain terms: Can CoQ10 prevent migraines?
Part of: 🧪 coenzyme Q10
Unclear. One small adult trial found it cut migraines, but a trial in children and a pooled analysis of adult trials found no benefit, so the evidence is too small and inconsistent to call it effective.

How far up the ladder this claim has climbed. A high consensus on a low rung means "consistent so far," not "proven in people."

How the studies fall
What the evidence shows
CoQ10 for migraine prophylaxis is contested, and the evidence splits evenly. On the supporting side, a small adult RCT (n=42) found it superior to placebo (50%-responder 47.6% vs 14.4%, NNT 3), and a dose-response supplement meta-analysis shows a preventive signal.

| Source | Grade | Stance | Quality | Finding |
|---|---|---|---|---|
| Tepper SJ, Tepper K 2025 · Current pain and headache reports | observational | supports | moderate | Narrative review states CoQ10 has 'Level C evidence for migraine prevention and low adverse events,' distinct from riboflavin/magnesium (higher evidence tiers) and butterbur/feverfew (safety caveats). No original n or effect size reported. |
| Orr SL, Venkateswaran S 2014 · Cephalalgia | observational | mixed | low | Pediatric nutraceutical review: CoQ10 among options but evidence limited in children. |
| Fajkiel-Madajczyk A, Wiciński M, Kurant Z, Sławatycki J, Słupski M 2025 · Antioxidants (Basel, Switzerland) | observational | supports | low | Narrative review concludes CoQ10 supplementation 'has resulted in many therapeutic benefits,' including decreased attack frequency/duration, reduced nausea, lower peak pain, and fewer migraine days across the studies it surveys. No pooled n |
| Slater SK, Nelson TD, Kabbouche MA, LeCates SL, Horn P, Segers A, Manning P, Powers SW, Hershey AD 2011 · Cephalalgia | RCT | contradicts | moderate | Double-blind placebo-controlled crossover add-on RCT in children/adolescents: CoQ10 did not significantly separate from placebo in the blinded phase (both improved). |
| Sándor PS, Di Clemente L, Coppola G, Saenger U, Fumal A, Magis D, Seidel L, Agosti RM, Schoenen J 2005 · Neurology | RCT | supports | moderate | Double-blind RCT (n=42 adults, CoQ10 3x100 mg/d): superior to placebo for attack frequency, headache-days, nausea-days at month 3; 50%-responder 47.6% vs 14.4%, NNT 3. |
| Talandashti MK, Shahinfar H, Delgarm P, Jazayeri S 2025 · Neurol Sci | meta-analysis | supports | moderate | Dose-response MA of dietary supplements for migraine prophylaxis: CoQ10 among agents showing a preventive signal. |
| Okoli GN, Rabbani R, Kashani HH, Wierzbowski AK, Neilson C, Mansouri B, Zarychanski R, Abou-Setta AM 2019 · Can J Neurol Sci | meta-analysis | contradicts | moderate | Okoli 2019 SR/MA of placebo-controlled RCTs (18 eligible; CoQ10 pooled 2 trials, 97 adults): CoQ10 'did not significantly decrease migraine frequency (mean difference (MD) -0.44 (-2.14 to 1.26); I2 53%; 2 trials; 97 participants; moderate strength of the evidence)', nor duration (MD -1.97, -4.82 to 0.87) or severity. Null on a directional claim = contradicts. Very small pooled base; authors call the evidence insufficient. |
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).
