Charlie M. reviewed Qualia Mind | Beta Tester
I felt very sharp on the days I took this product. I've supplemented with L-theanine for a number of years and estimate that a majority of the positive effects that I felt taking this product are attributable to that, particularly the overall sense of well-being and resilience. Effects that I experienced in addition to what I would normally experience with L-theanine included a heightened sense of attentiveness and improved reasoning ability.
