Roll Call does not check drug interactions or assess personal safety.
A water-soluble B-vitamin the body needs to convert food into usable energy and to support normal cell function. It occurs naturally in dairy, eggs, lean meats, and green vegetables, and is manufactured synthetically for supplements and fortified foods.
Why it’s used
Taken to meet daily riboflavin requirements, particularly by people with limited dietary intake, and sometimes explored for migraine prevention.
What the evidence is for
meeting riboflavin nutritional requirements and preventing deficiency.
What the evidence says
NIH's Office of Dietary Supplements confirms riboflavin's established role in energy metabolism and notes that deficiency is uncommon in populations with varied diets but can occur with poor intake or certain health conditions. Separately, some clinical trials have examined higher-dose riboflavin (around 400 milligrams daily) for reducing migraine frequency, with the evidence described as promising but not fully conclusive.
Dose studied
1.1–1.3 mg — adult RDA per NIH ODS.
Context
The adult Recommended Dietary Allowance is about 1.1 to 1.3 milligrams per day per NIH ODS. Migraine-prevention trials have used considerably higher doses, around 400 milligrams daily, for several months, a use distinct from ordinary nutritional intake.
