About

About Function Health

Function Health is a San Francisco-based preventive health platform founded in 2021 that provides members access to over 100 biomarker tests at an annual membership price — dramatically undercutting what these tests would cost through traditional healthcare. Co-founded by longevity physician Dr. Mark Hyman, Function has rapidly become one of the most talked-about diagnostics platforms in the longevity and biohacking communities.

Unlike prescription-focused telehealth providers, Function Health's core product is comprehensive lab data — covering hormones, metabolic markers, cardiovascular risk, immune function, micronutrients, and more — paired with AI-assisted interpretation and physician-supervised review. The platform operates in all 50 states and accepts HSA/FSA payments.

Function Health is ideal for patients who want to understand their full biomarker picture before committing to a treatment protocol, or who use it in conjunction with a prescribing provider like Marek Health or Hone Health. It represents the diagnostics layer of a comprehensive longevity stack.
