Riboflavin is a water-soluble B vitamin involved in energy production and in the function of other B vitamins in the body. It is naturally found in dairy, eggs, meat, and green vegetables.
Why it’s used
Taken to meet daily riboflavin requirements, and sometimes explored at higher doses for migraine.
What the evidence is for
correcting riboflavin deficiency.
What the evidence says
NIH ODS confirms riboflavin's role in preventing deficiency, which is rare in people eating a varied diet. Separately, some clinical trials have tested riboflavin at doses well above nutritional needs for migraine prevention, with mixed and not fully consistent results.
Dose studied
1.1–1.3 mg — adult RDA, per NIH ODS.
Context
Adult daily intake recommendations run 1.1 to 1.3 mg. Migraine studies have used doses around 400 mg per day, far above nutritional requirements, and this use is a distinct research question from ordinary deficiency prevention.
