Salivary lactate

tracking.

Unlock peak performance with the first mouth-worn sensor.

No blood, no lab, just results.

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

Traditional lactate threshold tests are invasive and tied to a lab. The iTOOTH delivers continuous and reliable salivary lactate data. No finger pricks, no lab visits, just real performance insights.

No gaps in the data. The iTOOTH tracks your lactate continuously throughout the test. You get the full curve, not just isolated points.
No needles, no blood. iTOOTH analyzes your lactate through saliva – completely pain-free and hassle-free.
On the treadmill, on the bike, or out on the track. No labs, no delays. iTOOTH goes wherever you go.
Simple enough to do wherever you are, often enough to accurately monitor progress. Just pop it in your mouth and test as often as you wish.

Lactate tracking directly in-mouth. Insights from your saliva.

The discreet intraoral sensor continuously monitors salivary lactate, a validated biomarker of metabolic exertion. Data is transmitted to the connected device for further processing. This provides actionable insights to accurately adjust your trainings in order to reach your goals without invasive sampling or laboratory processing.

Built on science. Designed for performance.

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

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

Monitor how your thresholds evolve, watch them shift, track your progress and adjust your training appropriately.

Each test becomes a checkpoint showing you what's working, what needs adjusting, and where to push next. Stop guessing and start building a smarter, more targeted path to peak performance.

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.
