I have had migraines for 24years. nothing seemed to work at all. By accident, I found a cure for them! I was using spirulina (12 capsules a day) for something else and I realized that I had gone two months with absolutely nooo headaches at all. I'm a very skeptical person when it comes to trying new things, but spirulina made me a believer. Try it and let me know how it works for you.
