Menstrual Migraine: The Evidence-Based Supplement Protocol

← Back to articles

Menstrual migraine — attacks linked to the perimenstrual estrogen withdrawal — affects roughly 50% of women with migraine. The pattern is more refractory to standard prophylaxis than non-menstrual migraine. Triptans (frovatriptan in particular has a short-term prevention indication) and hormonal stabilization remain primary. Among supplements, the migraine-prevention quartet adapted to menstrual timing has the cleanest evidence.

Magnesium, 360 mg Daily — Continuous With Premenstrual Boost

A 1991 RCT in 24 women with menstrual migraine showed magnesium pyrrolidone carboxylate 360 mg daily during the second half of the cycle reduced attack frequency and analgesic use versus placebo. The timing matters — daily continuous magnesium plus a premenstrual boost during days 15–28 of the cycle appears most effective. See our magnesium migraine piece.

Riboflavin (Vitamin B2), 400 mg Daily

Riboflavin at 400 mg daily reduced migraine frequency in the original Schoenen 1998 trial and has consistent positive replication. It addresses the mitochondrial-energy-deficit hypothesis of migraine. Useful in menstrual migraine as part of the broader prophylaxis quartet. See our riboflavin piece.

Vitamin B6, 50–100 mg Daily — Cycle-Days 15–28

Vitamin B6 has small trial signal in PMS-related symptom reduction including menstrual headaches, particularly when given in the luteal phase. Cap at 100 mg/day chronic — higher doses cause peripheral neuropathy.

CoQ10, 100 mg Three Times Daily

CoQ10 has the same migraine-prevention mechanism as riboflavin (mitochondrial cofactor) and reduces frequency in pooled trials. Part of the AAN-recommended migraine prophylaxis quartet. See our migraine prevention stack.

Feverfew (Standardized Extract), 100 mg Daily

Feverfew at 100 mg of 0.2% parthenolide extract has modest positive trial signal for migraine frequency. Discontinue gradually (rebound headache risk). See the migraine prevention stack for the broader context.

What NOT to Take

Avoid butterbur — hepatotoxicity from pyrrolizidine alkaloids; pulled from most markets. Avoid 5-HTP if on triptans or any serotonergic medication. Skip "hormonal balance" formulas that aren't endocrine-evidence-based. Avoid vitex (chasteberry) at high dose without gyn input in women trying to conceive or on hormonal therapy.

How to Run the Protocol

Track migraine days against menstrual cycle to confirm the menstrual-related pattern. Layer the migraine prophylaxis quartet (magnesium 360 mg + riboflavin 400 mg + CoQ10 300 mg + feverfew 100 mg daily). Add B6 50 mg during luteal phase days 15–28. Evaluate at 12 weeks; meaningful response is 50% reduction in monthly migraine days. If unresolved, neurologist consult re: triptan short-term prevention or CGRP-targeting therapy. See condition page.
