I am a student, with exams coming up, so thought I would give this brainzyme a try. They did make me a bit thirsty at first, so that required some focus in making sure I enough water every time. But its worth the 7 or so hours of solid WORK I am getting done. Worth a try for most, but not if you don't like drinking lots of water.

I take 3 brainzyme capsules with water when I need to get on with work. They help me stay calm and focused under pressure and the energy boost is good too.
