TimeTeller puts our internal clocks at the center of personalized medicine

German startup TimeTeller has developed a saliva test kit to help individuals understand their circadian rhythm, with the goal of reducing side effects from cancer treatments. The test kit works by analyzing a person's saliva to determine their internal clock, which can be disrupted by cancer treatments and other factors. This disruption can lead to side effects such as fatigue, weight loss, and sleep disturbances. By understanding a person's circadian rhythm, TimeTeller aims to help individuals adjust their treatment schedules and daily routines to minimize these side effects and improve their quality of life.
