    This product works for me (and my friends too)!!!
    I have had 4 strokes and have had memory and cognitive issues that resulted from them. I have tried many of the “popular” memory supplements with little improvement. When I had been using this product for only a month, my coworkers and family noticed significant improvements, so it’s not just my perception of the results. I have continued to use this product for over a year and a half and definitely recommend this product to anyone seeking to improve their memory or cognitive function!!! Several of my friends have now tried this product and are seeing similar results as me!!!

    Long term use not recommended
    I took this three times and a cold sore broke out on my lip on the third day. Could have been triggered by the amino acids in it. Other than that I felt pretty good. I haven’t taken it since and don’t really feel that different. Maybe a little more tired than when i was taking it. This product is B12 with folic acid and a blend of amino acids. I wouldn’t recommend taking this for long as B12 can build up in your body and cause problems. I know, it happened to me and i had to stop taking a B Complex that I was taking.
