Introduction:
It is not well established to use vitamin D supplementation for migraine, and this meta-analysis aims to explore the efficacy of vitamin D for migraine patients.
Methods:
PubMed, EMbase, Web of science, EBSCO and Cochrane library databases were systematically searched up to May 2021, and we included randomized controlled trials (RCTs) exploring the effect of vitamin D for migraine patients.
Results:
Six RCTs and 301 patients were included in the meta-analysis. Compared with control group in migraine patients, vitamin D supplementation could remarkably decrease headache attacks per month (MD = -2.74; 95% CI = -3.82 to -1.67; P < 0.00001), headache days per month (MD = -1.56; 95% CI = -2.44 to -0.68; P = 0.0005) and MIDAS score (MD = -5.72; 95% CI = -10.90 to -0.54; P = 0.03), but demonstrated no obvious influence on attack duration (MD = -2.20; 95% CI = -7.38 to 2.97; P = 0.40) or headache severity (MD = -0.56; 95% CI = -1.18 to 0.06; P = 0.08).
Conclusions:
Vitamin D supplementation provided additional benefits to treat migraine.
