Migraines can be exhausting and disruptive. Many people look for natural ways to reduce their attacks, and magnesium is one of the most studied options. But how effective is magnesium for migraine prevention? Let’s look at the research and practical considerations.
Why Magnesium Matters for Migraines
Magnesium plays a key role in nerve signalling, muscle relaxation, bone strength, and blood vessel function. (1) Low magnesium can trigger brain changes that set the stage for migraines. Research shows that many migraine sufferers have lower magnesium in their brain and tissues, even when blood tests appear normal. (2, 3, 4)
Evidence for Magnesium Supplementation
Clinical studies suggest magnesium can lower the frequency and intensity of migraines. (5, 6) Both the American Headache Society and the American Academy of Neurology classify magnesium as “probably effective” for migraine prevention. (7) The strongest benefits appear in people with menstrual migraines and those who experience aura before their headaches.
Choosing the Right Magnesium
Not all forms of magnesium are absorbed equally. Magnesium oxide is most studied for migraine prevention, but it can cause digestive upset in some people. Magnesium citrate and magnesium glycinate are often better tolerated. Magnesium glycinate, in particular, is gentle on the stomach and well absorbed. A common dose ranges from 400–600 mg per day, though your doctor may recommend a different amount.
A High-Quality Option in Our Office
Because quality varies widely between supplements, we carry Metagenics Magnesium Glycinate in our clinic. This professional-grade formula is well absorbed and easy on the digestive system, making it an excellent option for migraine prevention. If you’d like to try magnesium, our office can provide guidance on safe and effective use.
Is Testing Helpful?
Standard blood tests do not always reveal low magnesium because only 1% is found in the blood. More specialized tests, like red blood cell magnesium, provide better insight but are not widely available. For this reason, many doctors suggest a trial of magnesium supplementation even if test results look normal.
Safety and Considerations
Magnesium is generally safe, but high doses may cause diarrhea or stomach upset. People with kidney disease should avoid supplementation without medical guidance. As with any supplement, it’s best to discuss it with a healthcare provider before starting.
Conclusion
Magnesium for migraine prevention is a safe and affordable option with growing scientific support. While it may not work for everyone, many people experience fewer or less severe migraines after consistent use. If you suffer from migraines, consider magnesium as part of your care plan. Our office carries Metagenics Magnesium Glycinate, a trusted, high-quality option to help support your migraine prevention efforts.
