BackgroundMigarine is the most common headache around the world including Iran. In recent years, Vitamin D deficiency has been shown to a global health problem. A few studies have been determined inverse association between serum levels of Vitamin D with a headache. So, in this study, we investigated the effect of Vitamin D supplementation on symptoms and C-reactive protein (CRP) among patients with migraine.Materials And MethodsThis study was randomized, double-blind, and controlled-placebo clinical trial. Sixty-five migraine patients aged 10-61 years were included for analysis. Vitamin D was administrated for 10 weeks with 50,000 IU dosage of Vitamin D per week. Multivariate analysis of covariate and univariate analysis of covariate were done to determine the effects of Vitamin D supplementation on symptoms, including severity, duration, frequency of headache, and the headache diary result (HDR).ResultsMean headache frequency and HDR had significant difference among two groups (5.9 ± 7.0 vs. 7.0 ± 6.0, P = 0.06 and 85.0 ± 134.2 vs. 132.1 ± 147.1, P = 0.04). But, a mean difference of headache frequency was marginally significant (P = 0.06). These values were lower among the intervention group compared to placebo group. The association was not observed between CRP with migraine disease.ConclusionIn this study, we shown Vitamin D supplementation may be useful in decreasing frequency of headache attacks and HDR among patients with migraine.
