The evidence in words
How much to take
400 mg/day for migraine prophylaxis (give it 2–3 months); requirement is milligrams from food.
Timing & separation
There are no strict timing conflicts on record for Riboflavin (B2); consistency matters more than the exact hour for most goals.
Why the dose is what it is
As FAD/FMN it supports mitochondrial energy production; the migraine benefit is thought to reflect improved brain mitochondrial function.
Bottom line
A cheap, safe, guideline-backed migraine preventive at 400 mg/day. Give it a couple of months.
