Vitamin B2 (riboflavin) for migraine prevention. Dosing question.

Based on the clinical studies with vitamin b2 on migraines and articles on the possible role of mitochondrial dysfunction on the pathogenesis of migraines, I am planning to take riboflavin 400 mg/day as a prophylactic agent for chronic migraine.

My question to those who take this: Do you take the 400 mg at once, or do you divide the dose? I am planning to take all at once.

Another question: Would a lesser amount work equally well?

Thanks.

i used to take 200 mg of B2 and it really helped. vitamin B2 may upset your stomach unless you take it with food - try it and see. it will also make your pee bright yellow so be careful about white pants!!
