Zest: Longevity vs Nootka Saunas Usage & Stats

Ever wondered how old your body actually is on the INSIDE? Discover your Functional Age with Zest. For the first time in history, we have the tools to address aging at its core, and the science to help you to slow your rate of aging. A big part of this is tracking your body’s age on the inside and working to improve your metrics – which is where Zest comes in. Our app and simple at-home test dive deeply into your health, measuring everything from cardiovascular fitness, metabolic health, cognitive function and hormonal health. We use cutting-edge machine learning technology to analyze this data and give you an incredibly accurate measure of your Functional Age (your body’s age on the inside) which you can track and improve over time. Unlike chronological age, which simply counts years, functional age takes a holistic approach and looks at all of your body systems. How it works: 1. Unbox your at-home test: A simple finger prick and a few quick questions to get started. 2. Mail it back: We'll analyze your blood and digital biomarkers to reveal your Functional Age. 3. Results in-App: Dive into personalized insights about your body's performance. 4. Optimize your health: Get tailored recommendations to keep improving your functional age over time. Zest was built by a team of medical doctors, longevity scientists and researchers, and backed up by 100+ clinical trials. We are constantly updating and evaluating our recommendations to ensure we are consistent with the latest research. Are you ready to feel younger for longer? Let's redefine aging together.
