Migraines are more than just headaches—they’re complex neurological events that can disrupt daily life with intense pain, visual disturbances, nausea, and sensitivity to light and sound. Affecting over one billion people worldwide, migraines remain one of the leading causes of disability. While treatment often focuses on managing acute attacks, growing research suggests that prevention—particularly through addressing nutritional deficiencies—may be an equally important strategy.
Magnesium, an essential mineral involved in over 300 biochemical reactions in the body, has emerged as a promising player in migraine prevention. From regulating nerve signaling to stabilizing blood vessels, magnesium’s physiological roles intersect directly with processes implicated in migraine attacks. This evidence-based review examines the research behind magnesium supplementation for migraine prevention, the proposed mechanisms of action, and practical considerations for its use.
