Magnesium for Migraines – Benefits, Dosage & Best Type

Migraines can be intense and debilitating. Many people are now turning to magnesium for migraines as a natural solution. This essential mineral plays a key role in brain function, nerve health, and blood flow—making it a promising option for migraine relief.

Let’s explore how magnesium may help with migraines, the science behind it, how to use it, and important precautions.

How Does Magnesium Help in Migraine Relief?

Magnesium helps regulate neurotransmitters and nerve signals. In migraine sufferers, low levels of magnesium have been linked to increased brain excitability, which can trigger attacks.

Magnesium may help reduce migraine frequency and severity by improving nerve function and relaxing blood vessels.

• Relaxing blood vessels
• Reducing inflammation
• Improving nerve function
• Controlling serotonin levels

What Are the Signs of Magnesium Deficiency in Migraine Sufferers?

Many people with chronic migraines have low magnesium levels. Common signs of deficiency include:

• Muscle cramps or spasms
• Fatigue or low energy
• Nausea or vomiting
• Tingling in the limbs
• Sensitivity to light and noise

If you experience these symptoms regularly, magnesium deficiency could be contributing to your migraines.

Which Type of Magnesium Is Best for Migraines?

Not all magnesium forms are equally effective. The following types are commonly used for migraine management:

• Magnesium citrate – Easily absorbed, gentle laxative effect
• Magnesium glycinate – Calming effect, good for sleep and anxiety
• Magnesium oxide – Commonly studied for migraines, higher dose needed
• Magnesium threonate – Penetrates the brain barrier, supports cognition

Magnesium oxide is often used in clinical trials for migraines but may cause digestive side effects.

How Much Magnesium Should You Take for Migraines?

The recommended dose may vary depending on age, gender, and health status. However, studies suggest:

• 400–600 mg per day may help reduce migraine attacks
• Start with a low dose and increase slowly
• Take magnesium with food to reduce the risk of stomach upset

Tip: Speak to a healthcare provider before starting any supplement, especially if you have medical conditions.

How Long Does It Take for Magnesium to Work for Migraines?

Magnesium is not a quick fix. Some people may notice improvement within a few days, while for others, it may take 4 to 6 weeks of consistent use.

For best results:

• Take magnesium daily
• Track your migraine frequency
• Be patient and monitor changes over time

Can You Get Enough Magnesium from Food for Migraine Prevention?

Yes, but only if your diet includes magnesium-rich foods like:

• Leafy greens (spinach, kale)
• Nuts and seeds (almonds, pumpkin seeds)
• Whole grains (brown rice, quinoa)
• Beans and lentils
• Bananas and avocados

A balanced diet can support long-term migraine prevention, though supplements may still be necessary in deficiency cases.

Are There Any Side Effects of Using Magnesium for Migraines?

Magnesium is generally safe but may cause:

• Diarrhea or loose stools (especially magnesium citrate/oxide)
• Nausea if taken on an empty stomach
• Low blood pressure in rare cases at high doses

To avoid issues:

• Choose the right form
• Take with meals
• Do not exceed recommended doses
