Vitamin K2 Supplementation in Adult Episodic Migraine (ViKEM)

November 14, 2025 updated by: Sola Aoun Bahous, M.D. Ph.D.

Efficacy of Vitamin K2 Supplementation in Adult Episodic Migraine

Migraine is a debilitating illness and a major cause of disability in the world. It is highly prevalent, especially among women. Vitamin supplementation is a potential therapeutic option for migraines that remains largely under-explored. Several studies have shown that people with migraine tend to have higher arterial stiffness than people without migraine. Vitamin K2 deficiency is an important mediator of arterial stiffness and calcification due to decreased carboxylation of matrix Gla protein (MGP). Supplementation reverses these changes and improves vascular health in patients with end stage renal disease according to previous studies. Therefore, vitamin K2 supplementation could serve a potential role in migraine patients. The purpose of the study is to test the effect of vitamin K2 on decreasing the frequency of migraine attacks and decreasing arterial stiffness. The population will be recruited from the neurology clinic at LAU Medical Center-Rizk Hospital and will constitute of adult patients. They will be randomized to receive either the supplement of vitamin K2 or a placebo for the duration of 6 months. Laboratory tests and arterial stiffness measurements will be done at the beginning, middle, and at the end of the study for comparison.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Changes of monthly migraine days
Time Frame: 6 months
Effect of Vitamin K2 supplementation on the changes from baseline in monthly migraine days as compared to placebo. This will be assessed clinically using a questionnaire to be administered at the start, monthly, and at the end of the study (6 months) about frequency and number of migraine days per month.
