Dr. Elizabeth Yurth, MD: Muscle Building in Midlife, Joint Regeneration, Peptide Protocols, and Why Osteoarthritis Is Not Wear and Tear
Dr. Elizabeth Yurth, co-founder of Boulder Longevity Institute, is one of the rare physicians who spent 30 years in orthopedic and sports medicine before pivoting to longevity and regenerative medicine. This episode covers joint health in women, osteoarthritis, bone density, peptides, perimenopause, hormones, mitochondrial health, and the regenerative protocols most women have never been offered.
What she found after decades of patching people together: we have been thinking about joint disease completely wrong. Osteoarthritis is not a wear and tear condition. It is a metabolic disease driven by mitochondrial dysfunction, hormonal decline, and chronic low-grade inflammation, and it can be prevented, slowed, and in many cases reversed if you start addressing it at the root.
Most women wait until something breaks before paying attention. By then, the damage has been building for years. The interventions that actually work are available now. They are just not in the standard conversation.

Why osteoarthritis is not a wear and tear disease and what the research actually shows
How progesterone protects your ligaments, tendons, and bone (and why estrogen gets all the credit)
Why birth control creates the perfect storm for joint and ligament injury
Why mitochondrial dysfunction is at the root of joint disease, muscle loss, and brain decline and why you have to repair before you rev
Hip fractures carry a 25% mortality rate in women, and most have never had a DEXA scan
