Q. I started taking vitamin D3 supplements about a year ago when my doctor tested my blood and found out I was vitamin D deficient. Is it just a coincidence that my migraines and chronic headaches have almost disappeared? I’ve had them for over 25 years and I am glad not to be suffering.
A. There is not much research on this issue, but we found several case reports similar to your experience (Headache, Sept., 2009). Some investigators have noted that migraines are more common in areas where vitamin D deficiency is widespread (Journal of Headache and Pain, online May 13, 2010).
