Kronos Longevity Research Institute

Kronos Longevity Research Institute (KLRI) is a non-profit research organization focused on the study of human aging and the prevention of age-related diseases. Established in 1999 and headquartered in Phoenix, Arizona, the institute gained international recognition for leading the Kronos Early Estrogen Prevention Study (KEEPS), which investigated the timing of hormone therapy in menopausal women. KLRI's research portfolio emphasizes translational medicine, utilizing clinical trials to evaluate interventions such as hormone replacement and metabolic modulators. The organization has collaborated with numerous academic institutions and the National Institutes of Health to advance the science of longevity. While its primary operational phase has concluded, its findings continue to influence clinical guidelines for women's health and geriatric medicine.
