I have definitely felt an improvement in my brain health in taking this supplement - which coincided with starting a new, highly demanding job! However, I am not able to do as long of an intermittent fast on the days I take the Qualia Mind. Also, it is one of the worst tasting supplements I have ever tried (and so many pills to take each morning!) Any chance the company could add something to the formula to make it taste more appealing? It smells and tastes like a horse barn.
