Chronic migraines have caused me to lose some cognitive function, such as concentration, memory, and processing. The doctor said I'd regain this function after my medicine was stable, but I didn't want to wait, so I looked for holistic options and found this. It works!! When I take it, I feel so much better. I tried an experiment where I didn't take it for a few days and my memory quickly deteriorated. It simply helps I'm not sure why or how, but it does.
