About this trial
The goal of this clinical trial is to assess the feasibility of recruitment and adherence to a high-dose cocoa extract supplement in individuals diagnosed with episodic migraine. The main questions it aims to answer are:
* Will we be able to enroll 114 participants during the recruitment period? * Will participants take study pills daily during the pill-taking period?
Researchers will compare two doses of cocoa extract to placebo to determine the acceptability of higher doses of cocoa extract supplementation in this patient population.
Participants will be asked to:
* Provide two urine samples * Complete daily questionnaires * Take four study pills a day for 12 weeks
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Women and men aged ≥18 years
Self-reported clinician diagnosis of migraine with or without aura which does not meet criteria for chronic migraine (according to the International Classification of Headache Disorders 3rd edition)
Individuals with self-reported migraine will need to report a clinician diagnosis of migraine and be classified as having migraine or probable migraine by the American Migraine Study (AMS) migraine screener. The AMS migraine screener, which has a sensitivity of 100% and a specificity of 82% for the diagnosis of migraine will be used to confirm self-reported migraine status.
History of migraine dating for at least one year
Disqualifiers
Self-reported history of stroke or transient ischemic attack; history of brain surgery or spine surgery; currently receiving treatment for a concussion; and self-reported diagnosis of cluster headache, brain tumor, brain aneurysm, traumatic brain injury, multiple sclerosis, epilepsy, schizophrenia, or bipolar disorder
Kidney failure or current dialysis treatment or any medical condition which the participant believes could lead to difficulty complying with the protocol
Current alcohol or substance abuse (self-reported)
Self-reported clinician diagnosis of medication overuse headache

Trial outcomes
Primary outcomes
Recruitment
We will be able to recruit and randomize 114 eligible individuals
Retention
Retention will be quantified by the proportion of subjects who record their migraines for at least 22 out of 28 days during run-in and the last four weeks of the intervention and complete all questionnaires at baseline and follow-up
Adherence
Adherence will be calculated as the proportion of participants who miss no more than 12 days of study pills (i.e. participants will consume study pills on 85% of the intervention days)
Secondary outcomes
Migraine days
Number of migraine attacks as recorded in migraine diaries
Responder rate
Proportion of individuals who experience a ≥50% reduction in migraine days
Migraine severity
Four-point scale with categories of "absent, mild, moderate, or severe".
Adverse events
Potential side effects and adverse events
