I started taking the product because, at 51, I felt as though my cognitive abilities were beginning to diminish, especially in the afternoon. I would sometimes forget where I put things, and felt a little "fuzzy" at the end of the day. It took about a month to see the effects, but if you're looking for something to provide clarity, focus and boost cognition, this stuff really works. I'm back to my old self, don't forget where I put things, and am thinking as clearly and as fast as ever. I highly recommend it.
