About This Episode
Hormones are not single data points. Cortisol, progesterone, testosterone, and other hormones change across the day, cycle, sleep, stress, training, and context. In this episode, Dr. Hillary Lin talks with Marina Pavlovic Rivas, cofounder and CEO of Eli Health, about why one annual lab snapshot can miss dynamic physiology — and why more data still needs humility. We cover: - saliva testing and what it can/can’t show - cortisol curves vs cortisol panic - progesterone/testosterone tracking - wellness data vs diagnostics - why validated at-home testing is hard - how AI in healthcare depends on better inputs Educational only, not medical advice. *Chapters:* 00:00 The Importance of Hormonal Health 00:54 The Data Gap in Hormone Health 02:43 The Science Behind At-Home Saliva Testing 06:17 Understanding Cortisol and Its Impact 12:14 Personalizing Cortisol Data vs. Wearable Tracking Limitations 15:05 Identifying Overtraining and "Tired but Wired" States 18:43 Expanding into Sex Hormones: Progesterone & Testosterone 20:40 Tracking Protocols: Finding Trends vs. Creating Noise 23:44 The "Anytime, Anywhere" Design Philosophy 24:40 Understanding Cortisol and Performance 28:31 Factors Influencing Testosterone Levels 31:36 Regulatory Boundaries: Wellness vs. Clinical Diagnostics 35:18 The Future of Data in Personalized Medicine 37:39 The Realities of Deep-Tech Health R&D 39:04 Closing Insights for Longevity and Health-Tech Founders *Get Dr. Hillary Lin’s free longevity tips and newsletter:* https://www.hillarylinmd.com/subscribe *Learn more about Dr. Hillary Lin:* https://www.hillarylinmd.com/ *Explore CareCore:* https://carecore.io
