Casey W. reviewed Qualia Mind Essentials
I can feel a difference when taking the product. I tend to take a lower dose of 3 caps rather than 5. The only drawback is that after taking Focus in the morning, that night I often feel a slight negative impact on my mood. It is also pretty expensive, which is a major barrier for me at the moment, being a poor graduate student.
Honestly, I feel it's a bit too soon in the study term to provide a strong opinion one way or the other. I have not had any negative effects, but not sure there have been anything specifically positive either (yet :) ). This is the reasoning for my "middle of the road" rating, so far.
It's early on, so the verdict is out...
