    Clear & More Focus

    Hi, I was taking brain guard regularly for a few months then got off for a few months. I then noticed I was becoming more foggy in my memory and decided to order more brain guard. Whether it's a placebo or not, I definately feel that my thinking has become clearer and more focused.
