Key clinical point: Increased dietary niacin intake may have a beneficial effect on migraine outcomes in adults with inadequate niacin consumption and the effect seems to peak in patients with adequate niacin intake, with the threshold level being approximately 21.0 mg/day.
Major finding: The risk for migraine was lower among adults in the higher (18.4-26.2 mg/day: odds ratio [OR] 0.78; P = .004, and ≥26.3 mg/day: OR 0.74; P = .006) vs lower (≤12.3 mg/day) quartile of daily niacin intake, with t he risk of developing migraine reducing by 2.5% with every 1 mg increase in daily dietary niacin consumption (OR 0.975; P = .011) in those with dietary niacin intake of <21 mg/day, but no such association was observed in those with dietary niacin intake of ≥21 mg/day.
Study details: This was a cross-sectional study including 10,246 participants aged ≥20 years, of whom 20.1% experienced migraine.
