Supplements for Migraines
Three supplements with real migraine-prophylaxis evidence — and several marketing-heavy ones that don't work.
Migraine prophylaxis (preventing attacks) is distinct from acute treatment (stopping one in progress). Supplements have evidence only for prophylaxis — nothing beats triptans or CGRP antagonists for acute abort. For prophylaxis, three supplements have meta-analyses-level evidence supporting a real frequency reduction. Effects take 2–3 months to evaluate; commit to the protocol that long or don't start.
Evidence-rated supplements
American Headache Society and American Academy of Neurology both rate magnesium as 'probably effective' for prevention. Best for users with aura.
Dose: 400–600 mg elemental/day, split (glycinate or citrate)
Multiple RCTs show ~30% frequency reduction after 3 months. Works best for episodic migraine (<15 days/month).
Dose: 150–300 mg/day (ubiquinol preferred), with food
Meta-analyses support ~40% frequency reduction at prophylactic doses. Turns urine bright yellow (harmless). Well-tolerated.
Dose: 400 mg/day (high — well above RDA)
Traditional migraine herb with moderate trial evidence. Standardized MIG-99 extract has the best data.
Dose: 100–300 mg/day of standardized extract (MIG-99)

Reviews found a benefit
Systematic reviews concluded these improve an outcome tied to migraine, and none concluded no effect.

Lifestyle context
Identifying triggers via a migraine diary produces the biggest non-pharmacologic gains — sleep deprivation, dehydration, alcohol, and hormonal patterns are common. Regular aerobic exercise reduces attack frequency. Magnesium deficiency is particularly common in migraine patients.
When to see a clinician
Sudden severe 'thunderclap' headache, new headache pattern after age 50, headache with fever or neck stiffness, or focal neurological symptoms warrant immediate medical attention. Frequent migraines (>4/month) merit a neurologist visit — CGRP antagonists have transformed prevention.
