Lumen

Lumen is a science-backed metabolic health technology brand helping people better understand how their bodies use energy. Its innovative handheld device uses a CO2 sensor to analyse your breath and determine whether your body is primarily burning fats or carbohydrates for fuel. Paired with the Lumen app, the device transforms this data into personalised insights and daily recommendations around nutrition, meal timing, exercise, sleep and recovery. Designed to make metabolic tracking accessible at home, Lumen brings technology previously used in clinical and athletic settings into everyday life. With its focus on personalised, data-driven guidance, Lumen helps users understand their metabolism, support their fitness and weight-management goals, and make more informed lifestyle choices.
