I have tried quite a few supplements for focus and energy in the past couple years; one of which just so happen to be Qualia Mind (around this time last year). While Qualia Mind was the best supplement I had tested at the time, Qualia Focus has stood out as by far the BEST supplement I have ever tested. The amount of energy and focus I feel from this has been almost unbelievable. When I have to speak to a client or customer, I feel more mentally on my game and can recall words and vocabulary with lightning speed when I'm trying to convey my thoughts. When reading the desired effects of comparable supplements, they all claim to provide mental clarity, focus, and energy. I have never felt these effects with anything until Qualia Focus. When this becomes available permanently, I will be a life-long customer!
