There is a possible relationship between migraine and hypercoagulability inducing factors, such as hyperhomocysteinemia. In this context, homocysteine (Hcy)-lowering vitamins (B6-folate-B12) may prove beneficial in the management-prophylaxis of migraine. We performed a systematic literature search in order to retrieve studies assessing the supplementation of B6, folate and B12 (alone or as adjunctive therapies) to migraine patients, as well as patients suffering from other primary headache disorders. MEDLINE, EMBASE, CENTRAL, Google Scholar, trial registries and OpenGrey were searched. Twelve relevant articles were retrieved. The management of acute migraine attacks with Hcy-lowering vitamins has not provided promising results (one randomized controlled trial-RCT-and one prospective uncontrolled trial). On the contrary, significant benefits were registered for the use of B6 alone, in combination with folate and in combination with folate and B12 in the prophylaxis of migraine with aura (MA) in adults compared to placebo (five RCTs, only one did not obtain significant results). Folate supplementation alone was not more efficacious than placebo (one RCT). Limited data for the prophylaxis of migraine without aura (MO) in children (two prospective uncontrolled trials) and adults (two prospective uncontrolled trials involving both MA and MO participants) impede the extraction of safe conclusions. An overall attractive safety profile was exhibited with gastrointestinal adverse events being the most common. Overall, a potential beneficial effect regarding the administration of B6, folate and/or B12 in the prophylaxis of MA in adults was indicated. Additional high-quality RCTs that will investigate MO in adults as well as MO and MA in children are warranted.
