How was the TallyAge™ test built?Updated 9 months ago

Using an exceptionally large and diverse dataset spanning a wide age range, a machine learning model was used to identify DNA methylation sites that both correlate with holistic lifestyle factors - such as diet, exercise, sleep, alcohol, and smoking - and change with age. If someone that is 50 years old chronologically gets a TallyAge of 45, this means that their DNA methylation profile is more indicative of a chronological 45-year-old than a chronological 50-year-old.
