Key clinical point: Dietary vitamin C intake was negatively associated with the risk for severe headache or migraine.
Major finding: Each 1 mg/day increase in dietary vitamin C intake was significantly associated with a 6% lower risk for severe headache or migraine (adjusted odd ratio [aOR] 0.94; P = .0007). This inverse association between dietary vitamin C intake and severe headache or migraine risk was significant in women (aOR 0.90; 95% CI 0.87-0.85) but not in men.
Study details: This cross-sectional study included 13,445 participants from the National Health and Nutrition Examination Survey, of whom 2745 (20.42%) had severe headache or migraine.
Disclosures: This study did not receive any specific funding. The authors declared no conflicts of interest.
