TimeTeller 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.
