People who are deficient in vitamin D may be more prone to chronic headaches, according to a Finnish study. The study was designed for other purposes, but it found an intriguing link between the two.
The Kuopio Ischaemic Heart Disease Risk Factor Study:
The Kuopio Ischaemic Heart Disease Risk Factor Study collected information on headaches and serum vitamin D levels in 2,600 middle-aged men. Almost 10 percent of the volunteers reported that they suffered headaches every week or even more frequently.
Measuring Vitamin D Levels:
The researchers took blood samples to measure the amount of 25-hydroxyvitamin D in the men’s serum. Men who reported chronic headaches had 25-hydroxyvitamin D levels of around 38 nmol/L. Those who did not experience headaches averaged almost 44 nmol/L.
Men with the lowest vitamin D levels were twice as likely to have chronic headaches as those with the highest levels. The researchers suggest that these findings support the view that vitamin D may be helpful in headache prevention. It is not clear, however, whether vitamin D supplements can reverse this link and free men from frequent headaches.
