Short answer: Mental performance depends on multiple interacting factors — sleep, hydration, circulation, and nutrition — making a single supplement only one piece of a larger picture.
Why no single ingredient covers everything
Peak mental performance draws on foundational habits as much as any supplement — a product addressing circulation, for instance, doesn't compensate for poor sleep.
Where a supplement fits realistically
As one additional piece alongside foundational habits, not a replacement for them — a supplement's contribution is meaningful but partial.
💡 Worth knowing: setting expectations around "one piece of the puzzle" rather than "the whole answer" leads to more satisfaction with any product you choose.
