Does MTHFR cause migraines?

Yes, research suggests that MTHFR gene mutations may be linked to migraine. MTHFR is the most investigated genetic risk factor in migraine, especially migraine with aura. People with the MTHFR C677T mutation have a significantly higher risk of experiencing migraine with aura as well as with increased homocysteine concentrations, which is also linked to migraine.3

How is MTHFR related to migraines?

A mutation on the MTHFR gene impairs the body’s ability to convert folic acid to methylfolate, and methylfolate is a key component of the process required for metabolizing homocysteine for promoting SAMe and utilizing intracellular glutathione. If folate levels are low - which is common in people with MTHFR mutations - homocysteine levels may increase significantly. 

Deficiency in B6, B12 and folate, coupled with a MTHFR mutation, results in a significant DNA hypomethylation, which in turn plays a significant role in triggering migraine attacks.4

How does MTHFR relate to homocysteine levels?

Homocysteine is an amino acid naturally produced by the body which can lead to significant health issues if levels are too high. Normally, homocysteine is recycled into methionine (another amino acid), which is then used to create important neurotransmitters. This recycling process requires vitamins B12, B6, and folate. However, a lack of these vitamins means the body cannot properly convert homocysteine to methionine. Instead, homocysteine builds up in the blood, where it can cause serious damage to blood vessels as well as impairing neurotransmitter production.
 

People with a MTHFR mutation are at higher risk of elevated homocysteine as they are more likely to be low in folate, B12, and B6.5

Elevated homocysteine can lead to inflammation in the central nervous system (CNS) as well as causing cerebral vessels to dilate. This is thought to cause the pain associated with migraine.6

Oxidative damage to the lining of the blood vessels may also increase the likelihood of migraine.7

Relation to magnesium

Magnesium deficiency is a known risk factor for migraine. A lack of magnesium can lead to cortical spreading depression (CSD): a wave of brain cell depolarization in the cerebral cortex and other areas of the brain. When CSD occurs, nerve cells in the cortex become highly active then their activity is reduced. This process is thought to be linked to the aura phase that occurs before a migraine.8

Imbalances in magnesium and calcium levels can also disrupt NMDA receptor function, potentially triggering cortical depression. The NMDA receptor, which regulates glutamate release, depends on a precise balance of these ions. Magnesium blocks the receptor's calcium channel, preventing an excessive influx of calcium ions and protecting cells from damage. When magnesium levels are low, this regulation weakens, leading to increased glutamate activity, excitotoxicity, and oxidative stress. These effects are all linked to migraine onset.9
 

Magnesium supplementation has been shown to help prevent and alleviate migraine by improving mitochondrial function and energy production in the brain as well as reducing oxidative stress, which is a major cause of migraine.10

How does methylfolate help with migraines?

Methylfolate is the active form of folate, one of the nutrients involved in reducing homocysteine levels in the blood. Methylfolate works alongside vitamins B6 and B12 to convert homocysteine to methionine. A lack of methylfolate and/or reduced MTHFR enzymatic activity can result in increased homocysteine levels, and an increased risk of migraine.11


Studies show that supplementation with folate, vitamin B6 and vitamin B12 can decrease homocysteine concentrations, and may also reduce the frequency of headache as well as the impact of migraine on a person’s quality of life.12


Taking methylfolate has also been shown to decrease the severity of migraines with aura.13


One study found that supplementing with 2 mg folic acid, 25 mg vitamin B6 and 400 μg vitamin B12 significantly reduced homocysteine levels and migraine symptoms in people affected by migraine with aura. This study also showed that the MTHFR C677T genotype is a major factor in migraine, as people with the CC allele (which represents ‘no mutation’ have greater MTHFR enzyme activity) experienced a better response to folic acid supplementation than those with the TT allele (which represents a ‘double mutation’), who have much lower MTHFR enzyme activity and therefore cannot metabolize folic acid properly.14

MTHFR and Migraines

A migraine is a type of headache that causes moderate to severe throbbing pain on one side of the head.1 This pain may be accompanied by nausea, vomiting, sensitivity to light and/or loud noises, and sometimes also double vision or aura. Aura refers to the bright lights, lines, and shapes that appear in front of the eyes, and/or tinnitus or sounds in the ears.2


Around 25% of people who get migraines experience aura, which can occur before or during the headache. Auras develop gradually and typically last up to 60 minutes.


Recent research has shown that the MTHFR gene mutation may play a part in causing migraine, particularly migraine with aura.

Frequently Asked Questions about MTHFR and migraines

Does the MTHFR gene cause migraines?

Several studies have shown that the MTHFR C677T mutation is a common cause of migraines, especially migraine with aura. People with MTHFR mutations are unable to metabolize folic acid properly, which can lead to low folate levels in the body. Folate is essential for the breakdown of homocysteine, and low folate can lead to a buildup of homocysteine, which is a major factor in migraines.

Can methylated vitamins cause migraines?

No, studies show that methylated vitamins such as methylfolate (B9) and methylcobalamin (B12) can reduce homocysteine, a major cause of migraine symptoms.15 Although some research has shown that folic acid is effective in reducing migraine, methylfolate is the active form of folate that is absorbed more effectively by the body, especially in people with MTHFR mutations.16

Can high homocysteine levels cause migraines?

Yes, high homocysteine is a major factor in migraine risk, especially in migraine with aura (bright lights and shapes alongside the head pain). Homocysteine increases vascular inflammation and oxidative stress, which can then trigger migraine headaches.

What genetic mutation causes migraines?

The MTHFR genetic mutation is the most studied genetic risk factor for migraines, especially migraine with aura. People with the MTHFR C677T mutation are typically prone to higher homocysteine levels and also have a much higher risk of experiencing migraine with aura. 17
