Works for me!
I have been taking this for over a month now.  I will say that I have seen an improvement in mental clarity.  I have A.D.D. so I tend to be very scatter-brained and lose focus.  This has also helped with my memory.  I tend to to forget things due to distraction from my over-active brain.  As far as the immunity support goes, I feel that it works well.  I had a couple days where I felt like I was coming down with a cold but the symptoms never got bad and I recovered quickly.
