In a new study from the Chongqing Hospital of Traditional Chinese Medicine, researchers found vitamin D supplementation could reduce headache attacks per month and headache days per month among migraine patients.
They conducted a systematic review of clinical studies exploring the effect of vitamin D on migraine patients.
Data were included for six randomized controlled trials with 301 patients.
The researchers found that vitamin D supplementation could reduce headache attacks per month, headache days per month, and migraine disability assessment questionnaire scores.
But it had no obvious effect on attack duration or headache severity.
The team says the finding is based on only six randomized controlled trials, and all of them have relatively small patient samples.
Researchers need more randomized controlled trials with large patient groups to explore this issue.
