What this trial studies

This study investigates the impact of vitamin D supplementation compared to a placebo on the prevention of episodic migraines. Additionally, it evaluates the combined effects of vitamin D and omega-3 fatty acids versus a placebo with omega-3s on migraine frequency, severity, and related complications. The research aims to understand the biological mechanisms through which these supplements may reduce migraine attacks and associated inflammatory markers.

Who should consider this trial

Good fit: Ideal candidates are adults aged 20-65 with a diagnosis of episodic migraine experiencing 4 to 15 migraine days per month and low baseline vitamin D levels.

Not a fit: Patients with non-migraine headaches, serious health conditions, or those who do not meet the inclusion criteria may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new preventive treatment option for patients suffering from episodic migraines.

How similar studies have performed: While the combination of vitamin D and omega-3 fatty acids is a relatively novel approach for migraine prevention, previous studies have indicated potential benefits of these supplements individually.
