Salivary lactate tracking.

No blood, no lab, just results.

Unlock peak performance and faster recovery with a mouth-worn sensor built for athletes who train smarter.

Say goodbye to lab tests. Meet the mouth-worn lactate sensor.

Traditional lactate testing is invasive and tied to a lab. The iTOOTH delivers continuous salivary lactate data. No finger pricks, no lab visits, just real-time performance insights.

  • Get precise performance data, anytime. The iTOOTH continuously tracks your lactate levels and delivers real-time insights while you train.

  • No needles, no blood. iTOOTH analyzes your lactate through saliva – completely pain-free and hassle-free.

  • In the gym, on the bike, or out on the track – iTOOTH goes where you go. No labs, no delays – just smart data, whenever and wherever you need it.

Real-time lactate tracking right from your mouth.

The discreet intraoral sensor continuously monitors lactate levels in saliva, a validated biomarker of metabolic exertion. Real-time data is transmitted to a connected device, providing continuous actionable insights during training without invasive sampling or laboratory processing.

Built on science. Designed for performance.

01.

  • Use real-time lactate data to fine-tune your training intensity and avoid both overreaching and undertraining.

The sensor wearable leverages peer-reviewed research validating salivary lactate as a reliable biomarker of metabolic exertion.

02.

  • Monitor how your threshold evolves and adjust your training cycles for targeted performance improvements.

03.

  • Capture every session as actionable data with uninterrupted biomarker tracking for deeper insight and smarter decisions.

Engineered for performance. Grounded in science. Tested in the real world.

The iTOOTH is developed by engineers and designers committed to practical, field-tested solutions. Co-created with athletes and refined with input from sports scientists, it delivers lab-grade insights in high-performance sports environments.

Built with teams. Growing with purpose

We are working closely with endurance athletes, professional teams, and performance diagnostics labs to continuously expand our solution. By developing the wearable in collaboration with those who train and test at the highest level, we transform how lactate is monitored.
