Can vitamin B12 reduce the frequency of my migraines?

Vitamin B12 may help reduce the frequency of your migraines, according to some research, but talk to your doctor before taking B12 or any dietary supplement.

Vitamin B12 (cobalamin) is essential for the normal functioning of your nervous system and for the production of healthy red blood cells. Doctors don't know for sure what causes migraine headaches, but some experts think migraines may occur when blood vessels in the brain swell and press on nearby nerves, causing headache pain. Exactly how vitamin B12 could reduce migraines is unclear, but some research indicates that it might.

In one study, doctors in the Netherlands treated 19 migraine sufferers with a nasal spray containing vitamin B12 once daily for three months. Ten of the participants experienced reductions in the frequency of their headaches, from an average of about five headaches per month to about two headaches per month. More recently, an Australian study found that the prevalence of migraines was cut in half among a group of headache sufferers who took a daily supplement of vitamin B12, folic acid and vitamin B6 for six months.

More studies are needed to confirm that vitamin B12 may help migraine sufferers and determine who might benefit most.
