I think it’s natural to be skeptical about using any kind of memory improvement product. For some reason I purchased this one and now I’m glad I did. Yet didn’t want to offer a review until I gave it a good test. After receiving my second six month supply, I am comfortable reporting a significant difference in my recall. It’s so nice to converse without needing to seemingly constantly stop to remember a certain name, word, time or place. My age is 78, I’m active and not retired,
