Seems to help
I purchased this product because I was looking for something to make me more productive and to help me concentrate and focus. The first thing that I noticed was that it did not smell appealing at all. It smelled nothing like green apple (honestly, it smelled like fish food).  Luckily, it smells a little better than it tastes, but still not great. Textured drinks are rough for me, so I would recommend putting it in a smoothy or something other than water.<br /><br />As for the effectiveness, it did seem to help me focus a bit better. It did not make me jittery or give me that overcaffeinated feeling though. I did not notice a drastic difference, but it did seem to give me a boost. For me, I would not use it frequently simply because of the taste.
