Mitome Launches At-Home Mitochondrial Testing to Bring Longevity Science to Consumers

Mitome, a new biotechnology company focused on cellular energy and longevity science, has recently announced the launch of its at-home mitochondrial test, marking a major step in making advanced mitochondrial research accessible beyond academic and clinical settings.

Founded by nutritional biochemist and researcher Chris Masterjohn, PhD, Mitome is designed to help individuals understand how efficiently their mitochondria produce energy and how that capacity changes over time. Mitochondria, often referred to as the powerhouses of the cell, play a central role in human adaptation, resilience, and aging, yet until now their function has largely remained invisible outside of research labs.

“For decades, we’ve known that mitochondrial function declines gradually with age and shapes how the body adapts over time,” said Masterjohn. “What’s been missing is a practical way for people to see how their own cellular energy systems are functioning and how they can support their mitochondrial function over time.”

A New Frontier in Longevity Science

Interest in mitochondrial biology has surged in recent years as longevity researchers increasingly focus on cellular energy as a foundational driver of health span. Mitochondria regulate ATP production, metabolic flexibility, cellular signaling, and stress adaptation, making them central to how the body maintains function over decades.

Masterjohn has helped bring this conversation into the mainstream, most recently through his appearance on The Joe Rogan Experience, where he discussed the role of mitochondrial efficiency in aging and long-term resilience. That public interest, paired with growing scientific consensus, has created momentum for tools that make mitochondrial science more accessible.

From Academic Research to At-Home Insight

Historically, assessing mitochondrial function was limited to specialized research settings and often required invasive procedures such as muscle biopsies or access to highly specialized, rare disease expertise. Mitome bridges that gap by offering an at-home testing experience paired with advanced analysis of each person’s own unique mitochondrial pattern.

Rather than relying on indirect proxies, Mitome focuses on respiratory chain performance, providing individuals with a functional view of how their cellular energy systems are operating. The goal is not to label or diagnose, but to give people a deeper understanding of the biological processes that influence longevity and adaptation.

“This is about visibility,” Masterjohn said. “When people can analyze how their mitochondria are functioning, they can make more informed decisions about how to support cellular energy in ways that influence aging and long-term health.”

Designed for Long-Term Optimization

Mitome is built on the understanding that mitochondrial function is not fixed. Cellular energy production responds to nutrition, lifestyle, and environmental inputs over time. By supporting repeat testing, Mitome allows individuals to track how their mitochondrial function changes and understand how different inputs influence the rate of mitochondrial decline.

As longevity research continues to advance, this approach places mitochondrial function alongside other foundational metrics used to understand how the body adapts and ages.

Leadership Rooted in Science

Chris Masterjohn, PhD, brings more than two decades of experience in biochemistry, nutrition, and energy metabolism to Mitome. Known for his ability to translate complex science into practical frameworks, Masterjohn founded the company to close the gap between cutting-edge mitochondrial research and everyday application.

“Mitochondria sit at the center of how we age,” Masterjohn said. “If we want to talk seriously about longevity, we have to start with cellular energy.”
