I had been using another product, but wanted to improve my mental edge even more. Since Ultimate Bone Support had proved itself with improved hard evidence (DEXA scan) I figured the memory product would do so, also. Retrieval of words can still be problematic; however, I do believe there has been an uptick in memory overall. This situation varies so much from day to day due to many factors, especially how much sleep I've gotten, that it can be difficult to say specifically. I do think it is worth a serious try.
