Migraines affect more than a billion people worldwide, yet many sufferers never discover what may be contributing to their attacks. Growing research suggests that low levels of magnesium — an essential mineral involved in nerve function, energy production and blood vessel regulation — may be one overlooked factor.
Studies have found that people who experience migraines often have lower magnesium levels than those who do not, raising questions about whether nutrient deficiencies may play a larger role in headache disorders than previously recognized.
Researchers believe magnesium may help support healthy brain function by blocking certain pain signals, helping regulate blood vessel activity and reducing neurological changes associated with migraine aura.
Some studies have found that magnesium supplementation may help reduce the frequency and severity of migraine attacks, particularly among people who experience migraines with aura. In one trial, magnesium performed similarly to a commonly prescribed migraine medication for prevention, without serious side effects.
While magnesium is not a magic cure, the findings highlight the importance of addressing underlying nutritional status rather than simply masking symptoms. Factors such as poor diet, chronic stress, certain medications and digestive issues can all contribute to magnesium depletion over time. For many people, restoring healthy magnesium levels through diet and appropriate supplementation may offer a simple strategy to help support neurological health and reduce migraine burden naturally.
