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.
