On this episode of WellBuilt, Jon spoke with Pranitha Patil, Co-Founder and COO of Function Health, about redefining preventive healthcare through comprehensive diagnostic testing and actionable insights.

Pranitha shared how her personal health struggles—including PCOS, pre-diabetes, and high cholesterol—led her to question the traditional healthcare system. After years of self-experimentation and navigating a system that often prioritizes reactive treatment over proactive health management, she co-founded Function Health to give people access to deeper health insights and data-driven solutions.

Function Health offers an annual membership that provides extensive lab testing for 160 biomarkers, giving members the ability to track their health over time. Unlike conventional physicals that offer only a snapshot, Function’s model is built around continuous monitoring and empowering people with the tools and knowledge to take control of their well-being.

In this conversation, Pranitha and Jon explored the gaps in the healthcare system, the challenges of advocating for yourself as a patient, and how Function is democratizing access to lab testing that was once only available through elite functional medicine doctors. They also discussed the importance of behavior change—how simply having data isn’t enough, but the right guidance and support can help people translate insights into meaningful action.

Pranitha shared insights from Function’s 100,000+ members, revealing common trends in metabolic health, cardiovascular risk, and nutrient deficiencies, and how people are using this data to make lasting improvements. She also touched on how AI and machine learning will play a role in helping individuals personalize their health journey.

Tune in to learn how Function Health is shifting the healthcare paradigm from reactive treatment to proactive self-care.
