Clinical Trial Results
Zest supports faster thinking and better decision-making during the most cognitively vulnerable part of your day: right after waking.
Clinical Trial Results
Zest promotes a positive emotional state upon waking, helping you start your day with motivation and mental resilience.
Clinical Trial Results
Zest is designed to complement your natural biological rhythms — amplifying your body’s natural cortisol spike in the morning without interfering with sleep onset.
Clinical Trial Results
Zest is engineered for nighttime use — designed to activate about 8 hours later, without disrupting your ability to fall asleep.
Additionally, since the study, we've improved the formulation and capsule technology to prevent disruption of sleep from food-induced digestive activity.

Sleep inertia, sometimes referred to as a "sleep hangover", is that groggy, disoriented state many people experience upon waking. It typically lasts 30 minutes, but can last up to several hours, significantly impacting your morning productivity and well-being, with ripple effects throughout the day.
What we know about sleep inertia:
We've designed Zest to proactively release at the ideal time in the morning, with a sustained release of caffeine and other ingredients that work synergistically to reduce sleep inertia and improve morning alertness.
Our formulation's timed-release technology allows for optimal release and absorption of caffeine.
This means instant effects from the moment you wake up, instead of after 30 minutes, and no afternoon crash.
We don't believe in spraying and praying, and throwing every ingredient out there into a pill.
We believe in science and precision. Each ingredient we've is hand-curated and validated to support morning energy, focus, and mood, as part of an engineered delivery system to maximize their impact on your mornings.
