The relationship between Vitamin B12 and Migraine is weak. Vitamin B12 ranks 174 of 687 Migraine treatments we have analyzed.

Migraine is a chronic neurological disorder characterized by recurrent moderate to severe headaches often in association with a number of autonomic nervous system symptoms. The word derives from the Greek ἡμικρανία (hemikrania), "pain on one side of the head", from ἡμι- (hemi-), "half", and κρανίον (kranion), "skull".1

Methylcobalamin (shown) is a form of Vitamin B12. Physically it resembles the other forms of vitamin B12, occurring as dark red crystals that freely form cherry-colored transparent solutions in water. Vitamin B12, vitamin B12 or vitamin B-12, also called cobalamin, is a water-soluble vitamin with a key role in the normal functioning of the brain and nervous system, and for the formation of blood. It is one of the eight B vitamins. It is normally involved in the metabolism of every cell of the human body, especially affecting DNA synthesis and regulation, but also fatty acid metabolism and amino acid metabolism. Neither fungi, plants, nor animals are capable of producing vitamin B12. Only bacteria and archaea have the enzymes required for its synthesis, although many foods are a natural source of B12 because of bacterial symbiosis. The vitamin is the largest and most structurally complicated vitamin and can be produced industrially only through bacterial fermentation-synthesis.2

Strength of evidence

Vitamin B12 for Migraine ranks in the bottom 6% of condition-treatment relationships we analyzed.

Importantly, we found 2 studies that were randomized and controlled. Such studies are considered the most rigorous, and help to establish or disprove a cause-and-effect relationship between prospective treatments and conditions. So there may be some good evidence on which to make a decision about using Vitamin B12 for Migraine.

Amount of research
