  1. Day 1Phase 01 · Focus & Clarity

    Focus without the noise.

    Laser-sharp focus and steady, jitter-free energy from the first shot. Deep concentration that holds for hours, no crash, no 2pm dip.

    [+]App data & clinical detail

    Most focus aids spike you up, then drop you. The 2pm dip is the receipt.

    Sharper focus that holds for hours. Deep work feels effortless. Calm, not wired.

    How it works

    Lemon balm supports GABA receptors within 30 minutes. Alpha GPC raises acetylcholine, the brain's memory messenger.

  2. Day 14Phase 02 · Resilience

    Your sharpest weeks yet.

    Adaptogens reach full strength and your response to stress shifts. Mental fatigue fades, and consistent motivation becomes the new normal.

    [+]App data & clinical detail

    One bad email can still ruin a whole morning. Stress is the single biggest drag on a cognitive score.

    Scores trend consistently higher. Stress rolls off, recovery shortens. The afternoon dip stops being a daily event.

    How it works

    Ashwagandha and rhodiola compound with daily use. Week two is when adaptogens reach full effect.

  3. Day 30Phase 03 · Better Brain

    A measurably sharper baseline.

    Your cognitive baseline sits permanently higher. Problems feel simpler, thinking flows faster, and decisions come naturally, in work and everywhere else.

    [+]App data & clinical detail

    Good days shouldn't be a coin flip. The goal is a higher floor, not a lucky ceiling.

    Less variation day to day. Problems feel simpler, decisions come faster. A baseline you can track in the CONKA app.
