I recently came across a product advertisement on my Facebook feed. I am usually skeptical about these things, but I'll research anything that could potentially have an effect on my migraines. Has anyone seen or tried Migravent? On their website the supplement list includes the usual Butterbur, magnesium, Vitamin B 12, and Co-Q10. But they are very expensive at almost $40/bottle. I am just wondering if this is a useful product or a scam on migraine sufferers who would try almost anything for relief.
