Short answer: Before or alongside any supplement, several daily habits — hydration, sleep, and movement — have a direct, well-documented effect on mental clarity.
Why these foundational habits matter first
Even mild dehydration measurably affects cognitive performance — a genuinely high-leverage factor that costs nothing and works faster than any supplement.
Where a supplement fits alongside these habits
As an additional, complementary layer — not a substitute for hydration, sleep, or regular movement, which remain the more foundational levers.
💡 Worth knowing: addressing these habits first often means you get more genuine benefit from any supplement layered on top.
