Roll Call does not check drug interactions or assess personal safety.
A B vitamin involved in converting food into usable energy. "Mixed" on a label usually just indicates it is sourced from more than one form or supplier, not a different vitamin.
Why it’s used
Taken to meet daily riboflavin needs and to correct or prevent deficiency, which is uncommon where diets are varied.
What the evidence is for
preventing and correcting riboflavin deficiency.
What the evidence says
NIH's Office of Dietary Supplements describes riboflavin's established role in energy metabolism and in preventing deficiency. Riboflavin has also been studied at higher doses for migraine prevention, an area where evidence is more preliminary and separate from ordinary deficiency-correction use.
Dose studied
1.1–1.3 mg — adult RDA, per NIH ODS.
Context
The adult RDA is 1.1-1.3 mg per day, per NIH ODS. No tolerable upper intake level has been set, as excess riboflavin has not been shown to cause harm at typical supplement doses.
