About LEVL

LEVL has created a new paradigm in fitness and nutrition management through a non-invasive, simple and accurate measurement of acetone to calculate and predict fat loss using a simple breath.

Unlike urine and blood, the LEVL device measures low levels of ketones as the body shifts into an elevated fat burning state making it a useful tool for any diet and fitness plan. LEVL is ideal for those interested in human performance and obesity and weight management.

It all began with our founder, Brad Root, and his vision to build a technology company that provides the insight the world needs about their bodies to truly achieve their wellness goals. After seven years of research and development, the LEVL team launched a groundbreaking device that arms every person with a reliable method to predict the body’s individual fat burn and state of ketosis based on half of a century of proven breath science research.

USA manufactured device. FDA Class 1 registered.
