The active, phosphorylated form of riboflavin, an essential B vitamin involved in energy metabolism.
Why it’s used
Taken to meet riboflavin needs and correct deficiency, and by some for migraine support based on separate research using plain riboflavin.
What the evidence is for
preventing and correcting riboflavin deficiency.
What the evidence says
NIH's Office of Dietary Supplements confirms riboflavin's established role in preventing and correcting deficiency, which can cause skin and eye symptoms. Separate, smaller clinical trials have examined high-dose riboflavin for migraine frequency, with some positive findings, though this research is less extensive than the deficiency evidence.
Dose studied
1.1–1.3 mg — adult RDA for riboflavin, per NIH ODS.
Context
Migraine studies have generally used doses around 400 mg per day of riboflavin over several months, distinct from the much smaller amounts needed to prevent ordinary dietary deficiency.
