Daniel R. reviewed Qualia Focus
I can tell a big difference in my focus levels!
Focus
If you are looking for a totally natural way to enhance your focus and concentration, I highly recommend Focus from NeuroHacker. I has totally helped my performance at work.
Focus without being wired
Not as much energy as with other products, but that is good in a way. Great focus, but doesn't keep you up so you also have to have a good sleep habit.
Flow in a bottle
Fall into flow, default back to flow, nutrients for a mindful state, a playground construction set for performance.
