I HATE combined products! This would be fine if there were a lot of sources for Rosmarinic Acid, but there is not.: I only found one other source.
Update: More than five months using this product. I've noticed that if I forget to take it for a day or two I will wake up with that recognizable pre-migraine ill feeling in my neck, and it will develop into a migraine. So these definitely work if used consistently.
