Association Between Headache and Serum 25‐Hydroxyvitamin D; the Tromsø Study: Tromsø 6

Abstract

Non-migraine headache was associated with low levels of serum 25(OH)D. Although adjustment were done for possible confounders, this finding may still reflect lifestyle rather than causality, and further studies are needed to investigate this. No association was found between serum 25(OH)D and migraine.
