We're inventing tools to help you reset.
Zest is formulated to help you wake up alert, energized, and mentally clear — without needing to reach for coffee.
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.
