Functional Medicine Is Longevity Medicine: Dr. Robin Berzin on Biomarkers, AI, and the Future of ...

Short Summary:  What does a true longevity care model look like in practice—not just in theory? Alexia sits down with Robin Berzin, MD and founder and CEO of Parsley Health, the nation’s largest functional medicine and longevity clinic. A longtime force in personalized medicine, Dr. Berzin offers a rare window into how Parsley is merging diagnostics, clinical care, and innovation to shift the healthcare paradigm—from reactive to radically proactive.


In this conversation, Dr. Berzin unpacks the most important—and overlooked—biomarkers for healthspan, the cultural moment that catapulted longevity into the mainstream, and why many people are chasing biohacks while ignoring the root causes of the diseases they already have.


Inside this episode:

• The six biomarker domains that matter most—and why conventional labs fall short
• Why strength training and sauna are at the top of her own longevity list
• The truth about peptides, GLP-1s, and whether rapamycin is ready for prime time
• How Parsley is using AI to scale personalization—without losing the human touch
• What women really need to know about hormone therapy, inflammation, and hidden thyroid issues
• Why she believes estrogen may be “the new longevity drug”

Whether you're a clinician, a consumer, or somewhere in between, this conversation offers a grounded, data-informed look at what it really takes to extend not just lifespan, but healthspan.
