Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Vitamin E (alpha-tocopherol) has some scientific evidence supporting its use in the management of certain types of migraine, particularly menstrual migraine (also known as catamenial migraine). Several small, randomized, placebo-controlled trials have investigated Vitamin E supplementation (typically 400 IU/day) in women who experience migraines associated with their menstrual cycle. These studies have shown that Vitamin E may reduce the severity, duration, and frequency of menstrual migraine attacks. The proposed mechanism involves Vitamin E’s antioxidant properties and its ability to stabilize cell membranes, as well as modulate prostaglandin synthesis, which is thought to play a role in the pathophysiology of menstrual migraine. However, the overall quality and quantity of evidence is limited. Most studies have small sample sizes and short durations. There is a lack of robust, large-scale trials to confirm these findings and to establish Vitamin E’s efficacy in non-menstrual migraines or the general migraine population. Major neurology and headache society guidelines do not currently recommend Vitamin E as a first-line or standard treatment for migraine in general, though it may be considered as an adjunct for menstrual migraine based on the available evidence. In summary, there is modest scientific support for Vitamin E in the context of menstrual migraine, but evidence is insufficient for broader migraine prevention or treatment.
