30 minute brisk walk morning and evening has helped me far more than any nootropics I tried. I still try various 'stacks' that people suggest (often Tim Ferriss), and am currently on Ubiquinol, Creatine and Policosanol before bed. If I don't perceive any benefit after a month or two though, I tend to move on, as there's a huge commercial market wrapped around all of this, so evidence is required for me to keep spending.
