Reading this site's two opposite lists together — who it suits, and who should skip it — gives a clearer picture of who's likely to notice the most difference, and who likely won't.
Someone wanting general daily support, comfortable with a non-stimulant approach, willing to commit to the multi-week and multi-month timelines, and without any of the site's named medical exclusions — per this site's own combined framing.
Someone expecting a fast, dramatic change within days, or someone hoping for a treatment-level effect on a diagnosed cognitive condition — this site is direct that neither expectation matches what it's designed or positioned to do.
