How MX3 Works



Take a quick sample of saliva anytime, anywhere. Lab-accurate results are stored in the MX3 app.



Using the app’s dashboard, track hydration levels of individuals or teams over time. Spot trends in dehydration risks and adjust to users’ hydration needs.



Bodies perform better when properly hydrated. MX3 equips you to understand and adjust this critical factor.

Use the MX3 LAB anytime, anywhere. Simply take a quick saliva or sweat sample on the field or in the locker room.


MX3 is scientifically proven to measure biomarkers from saliva as accurately as a laboratory osmometer.


Your hydration level is recorded within seconds of taking a saliva measurement, and results immediately upload to your app.


The LAB can be used over and over by one person or entire teams. Just replace the disposable test strip after each measurement.


Test strips load easily into the LAB, and saliva measurements are made by simply placing the strip on the tip of the tongue.


The LAB can be used with or without Bluetooth or Internet access. Measurements can be taken anytime for immediate readings, then stored for later upload.
