I've had migraines for 30+ years. I currently take Imatrex as needed. I typically have 10-15 days of migraine pain each month. I started taking this product along with B1, Magnesium and Iron daily as recommended by my Neurologist. It took about 2 weeks to see any improvement. I now have about 4-6 days of pain monthly and they seem to be less severe. I'm very happy with the results I've experienced as well as the the products quality. iHerb also ships really fast! Very happy with them as well.
