I am a 71 yr old woman who has experienced some memory and clarity problems in the past year. My first order of RediMind was was a "what the heck...what to I have to lose?" Well, it works. I have nothing scientific to support this. I can only say that my memory has improved and I am thinking more clearly. I've just placed my second order of 3 bottles and I wish I hadn't waited so long, because I believe I've slipped a bit since running out. I'm convinced that RediMind makes a difference for me.
