We're big believers in science, data and you

We believe that a healthy metabolism is the key to better health, and that everyone can attain it.

Our story

Lumen began with twin sisters Merav and Michal - two Ironman winners, and PhDs in physiology. As scientists and athletes, they were passionate about developing a way to provide personalized nutrition, but knew the only way to measure metabolism was costly and time consuming.
So they teamed up with entrepreneurs with  experience building large companies;  Daniel, Dror, and Avi, and after two years of R&D, they developed the first Lumen prototype. Lumen measured metabolism in a single breath, in less than a minute, instead of an hour-long test in a lab!
After four years of hard work and hundreds of beta users, the Lumen team launched on Indiegogo. Lumen broke the $1 million threshold on IndieGogo in weeks, and now Lumen is leading the way in bringing personalized nutrition to the entire world.

Where does the name Lumen come from?

“Lumen” is a unit of luminous flux - the total amount of visible light emitted by a source of light - just as the lumen device sheds light on how our nutrition and lifestyle affect our metabolism with a single breath.
