What this research studies

You would take a cocoa flavanol supplement or a placebo and keep a diary of your headaches, symptoms, and any side effects during the study. The team will compare how often and how severe your migraine attacks are between the supplement and placebo groups. This pilot builds on a large prevention trial (COSMOS) that found fewer migraine reports in people taking a cocoa extract, and it focuses specifically on adults with migraine. The study may also collect symptom or biological data to help understand possible mechanisms behind any benefit.

Who could benefit from this research

Good fit: Adults (21 years and older) who have a diagnosis of migraine and experience recurring migraine attacks would be the ideal candidates.

Not a fit: People whose headaches are not migraines or who have medical reasons to avoid cocoa or stimulants like caffeine are unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, this could offer a low-side-effect dietary supplement option to help reduce migraine frequency or severity.

How similar studies have performed: A large randomized prevention trial (COSMOS) reported fewer migraine reports among older adults taking a cocoa extract (HR=0.85), so there is encouraging prior signal but dedicated migraine trials remain limited.
