Vitamin K2 for adults with episodic migraine

Efficacy of Vitamin K2 Supplementation in Adult Episodic Migraine

Not applicable Interventional Lebanese American University · NCT05943457

This will test whether vitamin K2 supplements can reduce how often adults with episodic migraine have attacks and lower arterial stiffness.

What this trial studies

Adults with episodic migraine who meet eligibility will be recruited from the neurology clinic at Lebanese American University Medical Center–Rizk Hospital and given either vitamin K2 (menaquinone‑7) or a placebo. Participants will complete a baseline migraine diary and be followed to compare changes in migraine attack frequency and measures of arterial stiffness. The trial targets people with 4–14 migraine days per month and excludes those on standard migraine prevention or with other primary headache disorders. Vascular outcomes are motivated by prior findings that vitamin K2 can reduce arterial stiffness in other patient groups, while migraine outcomes address a largely under‑explored nutritional approach.

Who should consider this trial

Good fit: Adults aged 18 or older with episodic migraine (4–14 migraine days per month for at least 12 months, meeting ICHD‑3 criteria) who complete the baseline diary and are not using listed prophylactic medications are ideal candidates.

Not a fit: Patients with chronic migraine (>14 days/month), mixed primary headache disorders, those on migraine preventive drugs, or with medication overuse are unlikely to benefit from this trial.

Why it matters

Potential benefit: If successful, vitamin K2 could offer a low‑cost option to lower migraine frequency and improve vascular health in affected adults.

How similar studies have performed: Prior studies have shown vitamin K2 can improve arterial stiffness and vascular calcification in patients with end‑stage renal disease, but using vitamin K2 specifically to reduce migraine frequency is largely untested.
