High doses of magnesium can help prevent this acute form of chronic headache. Doctors believe magnesium blocks signals in the brain, leading to migraines with an aura. They also suggest magnesium can prevent the release of pain-causing chemicals, and a decrease in magnesium levels may cause blood vessels in the brain to narrow, contributing to migraines.
An aura is a sensory disruption that can occur before a migraine. It can include visual disturbances and tingling, lasting about 5 to 60 minutes.

What Is Magnesium?

Magnesium is a mineral found in large quantities in every cell in your body. A form of nutrient that a body needs to stay healthy. A healthy amount of magnesium is used for many purposes in the body, such as regulating muscle and nerve function and helping to reduce the level of migraine intensity.

Where Do You Get Magnesium?

Foods containing magnesium are spinach, almonds, peanut butter, and whole grains. If your diet does not require these ingredients, you may need a dietary supplement to obtain the necessary magnesium to prevent migraines. Luckily, magnesium supplements are readily available. In addition, doctors can administer magnesium via a vein in a clinic if you are already experiencing a migraine attack.
How Much Should You Take?
It is essential to consult with your doctor before taking magnesium supplements. They may recommend starting with a light daily dose of magnesium. If approved for those experiencing migraines, then your doctor can increase the level of magnesium supplement.

How Well Does Magnesium Work?

Magnesium supplements have not been extensively studied for migraine prevention. However, some research indicates they may be beneficial based on five gold-standard studies conducted on migraine patients. In contrast, a second group received placebo pills.
One study found that people who took magnesium supplements had migraines on 43% fewer days than others given the empty placebo pills. Several other studies found that magnesium users had fewer migraine attacks than nonusers.
The American Academy of Neurology and the American Headache Society agreed that magnesium could prevent migraines.

Are Magnesium Supplements Safe To Consume?

Studies suggest magnesium supplements are safe but can cause some mild side effects, including:
Stomach cramps.
Various forms of magnesium supplements are easily accessible. Specific forms of magnesium are there for individual requirements that are more easily absorbed by the body. If you and your doctor decide to use magnesium to prevent migraines, it may take a few months to see any improvement.


Magnesium is needed for maintaining good health, but consuming it from a well-balanced diet is better than supplements. Talk to your doctor before taking magnesium supplements to determine what level of magnesium is required for your migraines.
