Tally Health was founded by the world’s foremost expert on longevity research, Dr. David Sinclair, on the principle that aging is a treatable medical condition. David’s decades of research and breakthrough discoveries at Harvard Medical School helped to create the proprietary DNA sequencing protocol that is used in the TallyAge™ test and age clock. Biological age is a more accurate measure of one’s unique rate of aging and overall health than chronological age. Tally Health members are given personalized and actionable insights which empower them to make the necessary changes to decrease their body’s biological age, extend their healthspan, and improve their overall wellness.
