This Vitamin Deficiency Causes Migraines and Headaches (and here is how to fix it)

More than 300 million people worldwide — about 6 to 7 percent of men and 15 to 18 percent of women — suffer from migraine headaches, which can last anywhere from a few hours to three days. An estimated 20 million migraine attacks occur every single day.

Despite that, it’s still one of the least understood and poorly treated medical disorders, as they are likely due to a complex interplay of genetic, environmental, and neurological factors that vary from person to person.
Adding to the complexity is that the experiences of those suffering from migraines also vary greatly. Aside from throbbing, searing pain, which may or may not be one-sided, some experience “auras” prior to onset, while others do not. Other symptoms that may or may not be present include nausea, vomiting, fever, chills, sweating, and/or sensitivity to light, sound, and smells.
What Causes Migraines?
There are a number of different theories about the cause of migraines, but no one hypothesis can explain the occurrence of migraines in all sufferers. These (sometimes conflicting) theories include:

  •  Changes in your brain chemical serotonin. When levels drop, blood vessels including those in your brain become swollen and inflamed, which can lead to migraine pain.
  • Vascular constriction in your brain; from initial blood vessel constriction and a drop in blood flow, followed by dilation and stretching of blood vessels, which activates pain-signaling neurons.
  • Excessive increase of blood flow in your brain. In direct contrast to the preceding theory, other research has found that migraines are not preceded by constriction and decrease in blood flow, but rather by an increase of nearly 300 percent. However, circulation then appears normal, or even slightly reduced, once the attack is in full swing.  
  • A neurological disorder related to nerve cell activity that sweeps across your brain, causing pain. In this case, it is thought that a wave release of neurotransmitters across your cortex can directly stimulate your trigeminal nerves, setting off the chain reaction that ends in the transmitting of pain signals.
  • A nervous system disorder originating in your brain stem. Your brain stem is your control center for alertness, perception of light, noise and smell, cerebral blood flow, cardiovascular function and pain sensitivity — many, if not most, of which are part of the symptoms of a migraine attack.Research has revealed that three clusters of cells in your brain stem are active during and after migraine. According to this hypothesis, abnormal activity in those cells could induce the sensation of pain, even when there are no pain signals being received from your brain membrane or blood vessels.
  • A disruption of the subtle energies circulating throughout your body, along with unresolved emotional issues that manifest in your body as headaches.
  • Mutation or dysfunction of certain genes.
Are Your Migraines Due to a Vitamin Deficiency?
In this latest study, vitamin B6, B12, and folic acid supplements were found to produce a two-fold reduction in migraines over a six-month period. Previous studies, such as a 2004 study in the European Journal of Neurology, have also reported that high doses of B2 (riboflavin) can help prevent migraine attacks.
Certain gene mutations and dysfunctions can lead to higher levels of homocysteine production, which can make you more susceptible to migraine attacks. Here they found that vitamins B6 and B12 work by reducing your homocysteine levels. They also discovered that depending on your genotype, you may need a higher or lower dose in order for it to work. Said Professor Lyn Griffiths:
“… if all patients received the same vitamin dosage for the same period of time it would be expected that those with TT genotypes, having a reduced enzymatic rate, would metabolise less homocysteine over the treatment period compared to C allele carriers, thus resulting in a smaller reduction in homocysteine and consequent migraine symptoms.

  • Indeed, it may be that TT genotypes although having a higher risk of disease actually require a larger dosage of vitamins to exhibit the same effect as C alleles. Further clinical trials of much larger patient cohorts are required to test this hypothesis.”
    According to Professor Griffiths, their aim is to determine the optimal dosage of B vitamins based on your genetic profile.
    “The success of our trial has shown that safe, inexpensive vitamin supplements can treat migraine patients,” she said.
    However, there may be yet another, even more widespread, vitamin deficiency underlying your migraine symptoms.
    Just last year, researchers presented results of an observational study at the 50th Annual Meeting of the American Headache Society, showing that nearly 42 percent of patients with chronic migraine were deficient in vitamin D. The study also showed that the longer you suffered from chronic migraines, the more likely you are to be vitamin D deficient.
    This is yet another brand new discovery that can be tacked on to the literally hundreds of health ramifications of being vitamin D deficient.
