Roll Call does not check drug interactions or assess personal safety.
Riboflavin is a water-soluble B vitamin the body uses to convert food into usable energy. Riboflavin 5'-phosphate is its active, phosphorylated form, sometimes used because it does not require an extra conversion step in the body.
Why it’s used
Taken to meet daily riboflavin needs and, separately, sometimes taken by people looking into migraine prevention.
What the evidence is for
reducing migraine frequency at high supplemental doses.
What the evidence says
NIH ODS confirms riboflavin is essential for energy metabolism and that deficiency is rare in people eating a varied diet but can occur with poor intake or certain conditions. Separately, several clinical trials have looked at high-dose riboflavin (well above the RDA) for reducing migraine frequency, with some showing modest benefit, though study quality and size vary and it is not considered a settled first-line finding.
Dose studied
1.1–1.3 mg — adult RDA, per NIH ODS.
Context
The adult RDA is 1.1-1.3 mg/day. Migraine trials have generally used doses far above the RDA, commonly cited around 400 mg/day, over periods of three months or more, in adult populations with frequent migraine.
