I take Focusene daily. I rely on Focusene to even out my thinking patterns and avoid attention challenges, especially on stressful days.
It does seem to increase focus and clarity.
I used Focusene for a couple of years and felt a big difference. I did have to go off it though as I started to develop headaches and pressure in my head because of the ginkgo biloba. After a couple years off and mostly still doing well I recently decided to go back on but at a lower dose for another boost.
I definitely found a difference in my ability to concentrate when on Focuscene
