Nutrion™

Portable breath acetone monitoring.

Nutrion™ enables repeated, non-invasive measurement of breath acetone outside the laboratory. The system combines a handheld analyzer, guided mobile measurements and centralized data access.

How it works

From one breath to a measurable trend.

Breath acetone reflects changes in fat metabolism. Nutrion™ makes it possible to measure this biomarker repeatedly beyond the laboratory, helping users, professionals and researchers observe metabolic patterns over time.

Applications

Designed for repeated measurements in real-world settings.

Personal monitoring

Follow how nutrition, activity and daily routines are reflected in breath-acetone measurements. The Alivion Core app guides each measurement and makes changes over time easy to understand.

Professional programs

Integrate repeated breath-acetone measurements into structured nutrition or weight-management programs. Longitudinal data can support more informed conversations and individualized guidance.

Research studies

Collect frequent, non-invasive measurements in field, academic or clinical research settings. Nutrion™ supports longitudinal studies investigating metabolism, nutrition and exercise.

Evidence

Built on research. Designed for use beyond the lab.

The Nutrion™ measurement platform was developed collaboratively by ETH Zurich and Alivion. Peer-reviewed studies have evaluated breath-acetone sensing against established reference methods, including mass spectrometry and blood ketone measurements.
