The technology used in labs, now at your fingertips.

Unlock your metabolism
The CO2 concentration is measured using a unique breath maneuver, which is performed by inhaling a fixed volume of air through the Lumen device (dynamic to each individual), holding it for 10 seconds, and exhaling fully.
How do you measure metabolism?
The only way to measure your metabolism was in a hospital or clinic with a costly and time-consuming test known as RER (through the breath).
Lumen uses RER as the core data point to bring the same measurement to a home environment by measuring the CO2 in your breath through the sensor and flow meter, based on the RER metric.
Lumen's technology has been scientifically proven to accurately measure metabolic fuel usage when compared to the gold standard (RER) for measuring metabolism in multiple validation studies.
When measuring metabolism, Lumens results are comparable to that of the gold standard.
