I originally left a 3 star review because I didn't think the product did that much. If I wanted quick energy, I would just take caffeine - I love my coffee. However, I know all of the caffeine isn't good for me.
Anyway, I'm posting an update because the truth is that after 2 months of using it, I now have realized Body-brain Energy really does work. It's not a quick jolt, it's just smooth and long lasting the entire day. It takes about an hour or so to really kick in for me. However, I no longer have any mid-day crashes. I can keep going. I don't get tired, especially mentally. I feel like as if I slept great every night, even though I don't.
The point is that it does work, but you have to be patient. I really noticed it when I went on a trip and forgot to bring my bottle. Actually, I didn't forget, I just didn't want to bring more "stuff". And I'll tell you, when I got home and I started taking BBE again, THAT is when I really noticed and realized just how effective the stuff is.
