About

At MASI Books, we believe knowledge is the foundation of longevity. Our mission is to make the science of healthy aging accessible through clear, practical, and research-backed books. Each title translates breakthrough discoveries into everyday steps anyone can follow.

Our collection spans the key pillars of longevity — from nutrition and sleep to movement, mental resilience, and social connection. Whether it’s The Sinclair Protocol, The Longevity Diet That Ended the Debate, or Eight Pillars of a Longer Life, every book combines rigorous research with actionable strategies to help readers extend healthspan and thrive into later years.

MASI Books is part of MASI Longevity Science, a company dedicated to advancing the science of living longer, healthier lives. By blending Harvard-backed research, real-world examples, and step-by-step guidance, we give readers the tools to reclaim vitality, prevent decline, and chart a sustainable path to 90, 100, and beyond.

This is more than reading. It’s a roadmap to living better, longer.
