Migraines — The Role of B Vitamins in Headache Prevention

B vitamins, particularly riboflavin (B2), folate, and B12, play important roles in neurological function and energy metabolism that are directly relevant to migraine prevention. Ensuring adequate B vitamin intake through a nutrient-dense diet is a scientifically grounded dietary strategy for reducing headache frequency.
Migraines are neurological events producing intense, one-sided throbbing or pulsing pain accompanied by nausea, vomiting, and extreme sensitivity to light and sound. The cellular energy production processes that B vitamins support are important for maintaining the neurological stability that keeps migraine frequency low.
Riboflavin, or vitamin B2, has been specifically studied as a migraine prevention nutrient. It plays a central role in mitochondrial energy production, and research suggests that migraine-prone individuals may have impaired mitochondrial function that can be partially corrected by adequate riboflavin intake. Foods rich in riboflavin include eggs, almonds, lentils, tofu, and Greek yoghurt, all of which feature prominently in migraine prevention dietary recommendations.
Folate and B12 support the production and regulation of neurotransmitters including serotonin, which plays a critical role in pain modulation. Low levels of these nutrients can impair neurotransmitter function and increase pain sensitivity. Legumes like lentils and chickpeas, eggs, and leafy green vegetables are good dietary sources of folate. Eggs and Greek yoghurt provide B12.
The overlap between B vitamin-rich foods and the broader migraine prevention diet is significant. A diet built around eggs, lentils, tofu, quinoa, chickpeas, almonds, Greek yoghurt, and leafy vegetables naturally provides the B vitamins needed for neurological health alongside the protein, magnesium, and blood sugar stability that collectively reduce migraine risk. Regular medical supervision remains important for anyone with frequent migraines.
