GoKawiilTimeTeller launches saliva test to map circadian rhythm for personalized care
TimeTeller, a German startup led by CEO Angela Relógio, is now selling a direct-to-consumer saliva test kit that measures a person's circadian rhythm. Relógio, a physicist and former oncology researcher, says the company began taking direct orders due to demand from longevity clinics seeking data to personalize sleep, nutrition and activity advice. She stresses the consumer kit does not yet determine optimal timing for cancer treatments, which requires separate clinical research.
GoKawiil's interpretation of the reporting above, not reported fact.
The company's long-term ambition is to use circadian data to time cancer treatments for fewer side effects and better outcomes, a goal Relógio says still requires dedicated clinical studies rather than the consumer kit itself. Positioning the product first through longevity clinics could let TimeTeller build a market and data set before tackling harder medical applications like oncology, diabetes or Alzheimer's. The cautious framing also distinguishes it from past at-home testing scandals, suggesting the founder is trying to manage expectations about what current science supports.
- TimeTeller sells a saliva kit to measure individual circadian rhythms.
- CEO Angela Relógio says the consumer version cannot yet guide cancer treatment timing.
- Demand from longevity clinics, not cancer care, drove the shift to direct-to-consumer sales.
