Evidence-Backed Supplements for Migraine & Headaches
Migraine and recurrent headaches drive many people to look for preventive options beyond prescription drugs, often to cut attack frequency or ease the nausea and light sensitivity that come with them. The evidence here is uneven. Among the better-studied options, magnesium and coenzyme Q10 have the most consistent trial support for reducing migraine frequency, though effects are modest and work best as daily prevention rather than acute relief. Omega-3 fatty acids and melatonin show promising but still-mixed results, with melatonin studied mainly for migraine and cluster headache. Caffeine is double-edged: it can abort an early attack and boosts some pain relievers, yet overuse and withdrawal are themselves common headache triggers. Ginger has small studies for migraine-related nausea, and curcumin remains early-stage and exploratory. None of these is a cure, and responses vary widely between individuals.
