Updated September 2026
What the evidence actually shows
Moderate. The 2012 AAN/AHS guideline rated riboflavin “probably effective” (Level B) for migraine prevention, largely on a small trial of 400 mg a day in which the benefit took about three months to appear. It is very safe; the main side effect is harmlessly bright-yellow urine.
Commonly used: 400 mg/day for at least 3 months.
How this list is built: these are vitamin b2 (riboflavin) products ranked by real cost per dose across our whole vitamin b2 (riboflavin) catalogue — not filtered or re-ordered by migraine prevention. We don’t hold per-product evidence for a specific use, so we don’t pretend to rank for one. Products whose own label says they are for something else are left out.
