Description

Zest offers a comprehensive approach to understanding and improving long-term health. It combines what it describes as the world's most accurate biological age test with personalized, science-backed supplement regimens and a dedicated smartphone application for progress tracking. Developed alongside leading researchers and medical doctors, Zest aims to empower users to take control of their aging process.

The platform's ecosystem revolves around testing to establish a baseline, optimizing health through tailored interventions including high-quality supplements, and continuously tracking progress. By analyzing a combination of blood biomarkers, digital inputs, and functional tests through a machine learning algorithm, Zest calculates a functional age and provides users with actionable insights and tools to pursue a longer, healthier life. This system is designed to make longevity science accessible and easy to integrate into daily routines.

Key Features

Frequently Asked Questions

What’s included in the Zest membership?

The Zest membership includes your chosen longevity supplement stack delivered monthly, a Zest longevity blood panel delivered every 3 months (an at-home finger-prick test for 9 key biomarkers), access to the Zest app, and Zest biological age calculation (coming soon).

What’s the difference between the supplement subscription and the full membership?

The supplement subscription includes only supplements and app access, with no blood tests. Without the blood biomarkers, Zest is unable to calculate biological age.

How are longevity molecules different from mainstream supplements?

Mainstream supplements typically augment dietary ingredients. Longevity molecules are not usually found in regular diets, have no established daily recommendations, and are based on recent research to biologically slow aging, targeting the aging process as a whole rather than specific diseases.

How is functional age different to other biological age calculations?

Zest’s functional age calculation is described as the most accurate and holistic, uniquely including cognitive function alongside physical health. It uses a machine learning algorithm on a combination of blood biomarkers, digital biomarkers (like resting heart rate, sleep, mood, VO2 max), and functional biomarkers (like grip strength and memory tests).

Why can’t I choose exactly what goes into my supplement pack?

Zest aims to simplify longevity by having a team of medical doctors and longevity scientists curate and continuously update the supplement stacks based on the latest research. This ensures users receive optimal, cutting-edge ingredients without needing to conduct extensive personal research.
