Lumen is the world’s first hand-held, portable device to accurately measure metabolism.
Once available only to top athletes, in hospitals and clinics, metabolic testing is now available to everyone.
The science isn’t new, but the technology is.
Lumen uses a CO2 sensor and flow meter to determine the CO2 concentration in a single breath. This indicates the type of fuel your body is using to produce energy.
Know what and when to eat to fuel your workout, improve your metabolic flexibility and support fat burn.
Track your

Over time, Lumen tracks your metabolism, sleep, nutrition, and fitness data to provide a Lumen Flex Score, which reflects your success and helps sustain results.
