Healthcare providers and institutions can order TimeTeller test kits centrally for distribution to patients or members.

A study published in *eBioMedicine – The Lancet Discovery Science* links circadian rhythm disruption to cancer treatment side effects and suggests personalized chronotherapy.

Nina Ruge interviews Prof. Dr. Angela Relógio about her research on the connection between the human internal clock and topics like physical activity, cancer, and neurodegeneration.

Nearly every molecular and physiological process—including metabolism, immune function, and regeneration—is influenced by the 24-hour circadian clock, affecting areas like women’s health, shift work, and space medicine.

TimeTeller CEO Prof. Dr. Angela Relógio delivered a keynote at the Future Leaders Summit in Hamburg, discussing circadian biology and entrepreneurship.

At TimeTeller students have the chance to gain practical experience in bioinformatics, computational biology, data analysis and AI.

The TimeTeller Saliva Test identifies circadian rhythm imbalances that may affect sleep, mood, and health.

TimeTeller explores whether medicine could better incorporate the human body’s natural rhythms.

TimeTeller applies circadian biology to develop diagnostics that optimize health and personalize medical treatment timing for individuals and healthcare professionals.

Circadian rhythms and molecular processes vary among individuals. Adjusting sleep, movement, daylight exposure, or medication to a person’s internal clock can support health and reduce recovery times.

Circadian rhythms vary by individual, and aligning sleep, activity, light exposure, or medication with a person’s internal clock may improve health and treatment outcomes.

TimeTeller’s technology measures an individual’s biological clock under real-life conditions, based on research in chronobiology and systems biology.
