Prevent migraines
Studies have shown that vitamin B2 may help prevent migraines. One study found that taking a riboflavin supplement reduced the frequency of migraines by half in people who suffer from migraines with aura. Aura is a visual or sensory disturbance that can occur before or during a migraine headache. (3)
Another study found that taking a riboflavin supplement reduced the severity and duration of migraines in people who suffer from migraines without aura.
