There are so many products out there in the market, it's hard to believe what works! I thought I'd give CocoaVia Memory & Focus a try because it was endorsed by Katie Couric. I think she's pretty reputable. I also knew I would have to take these capsules for a time in order to see any results. Another plus is that you take 1 pill, not 2, or multiple pills at different times of the day. Well, I have REALLY noticed a difference! I feel I'm much more focused, and sometimes I surprise myself that I can actually remember some things that previously I would've been in a fog about. I saw results at about 6 weeks. I'm definitely sold on this product and will continue to use them.
