Folic acid intake and migraines

January 24, 2015

A study by Australian doctors led by Dr. Lyn Griffiths confirmed a previous observation that higher dietary intake of folic acid leads to lower frequency of migraine headaches. A 2009 study by Spanish doctors showed that patients with migraine with aura are more likely to have high homocysteine levels in their blood, a condition that can be corrected by taking folic acid and other B vitamins.

The authors of this new study have shown before that folic acid, vitamin B6, and B12 supplementation reduces migraine symptoms in patients with a certain genetic mutation (MTHFR gene), which leads to high homocysteine levels. However, the influence of dietary folate intake on migraine has been unclear. The aim of their current study was to analyze the association of dietary folate intake with migraine frequency, severity, and disability.

They studied 141 adult caucasian women with migraine with aura who had the MTHFR gene C677T variant. Dietary folate information was collected from all participants. Folate consumption was compared with migraine frequency, severity, and disability.

A significant correlation was observed between dietary folate consumption and migraine frequency. The conclusion of this study was that folate intake may influence migraine frequency in female sufferers with migraine with aura.

Good dietary sources of folic acid include spinach, lettuce, avocado, and other vegetables. If you suffer from migraine with aura you may want to ask your doctor to check your homocysteine level, as well as levels of folic acid and vitamin B12. Vitamin B12 level is not a reliable test because it can be normal even when a person is deficient and that is why it is important to check homocysteine level as well.
