Multiple Choice

Which of the following represents other migraine treatment options mentioned beyond standard analgesics?

A key idea here is that some non-prescription supplements have evidence supporting their use to prevent migraines, not just treat them acutely. Among the options, Coenzyme Q10 and magnesium have the strongest support for reducing how often migraines occur. Magnesium helps stabilize neuronal excitability and vascular tone, and it may modulate pathways involved in migraine pathophysiology such as NMDA receptor activity and calcium channel function. Deficiency has been linked to migraines, and many patients use about 400-600 mg of elemental magnesium per day in divided doses. It is generally well tolerated, though it can cause GI upset and should be used with caution in those with kidney disease. Coenzyme Q10 supports mitochondrial energy production, and migraines are thought to involve mitochondrial dysfunction in some people. Clinical trials have shown a reduction in attack frequency and severity with CoQ10, typically at 100-300 mg daily, with good tolerability. The other pairings—vitamin B12 with calcium, omega-3s with zinc, or iron with folate—have less consistent or weaker evidence for migraine prevention, making them less reliable choices for this purpose.
