riboflavin (vitamin B2) helps prevent migraines
Preliminary evidence suggests that riboflavin (vitamin B2)helps prevent migraines. On average, it reduces the frequency ofmigraines from four attacks a month to two.
Researchers are using HIGH doses...400 mg/day of riboflavin.This is over 200 times higher than the RDA...but toxicity isn'tlikely in people with normal renal function.
Riboflavin is sold OTC in 25, 50, and 100 mg tabs.
