Most people think biological age is just one number.
It isn't.
In this conversation, I'm joined by Dr Sandra Kaufmann, physician, cellular biologist, longevity expert and creator of the Kaufmann Protocol, to explore what biological age really means and why measuring it accurately is far more complex than most people realise.
We discuss why healthspan matters more than lifespan, why focusing on a single biomarker can be misleading, and how true longevity comes from understanding the body as an interconnected system rather than chasing individual health trends.
Inside this episode, we cover:
• The difference between lifespan and healthspan
• Why biological age is more than a single test result
• The limitations of telomeres, epigenetics and NAD testing
• Why researchers often become too focused on one area of ageing
• The seven cellular mechanisms that drive ageing
• How mitochondria, inflammation and DNA repair influence longevity
• The role of sirtuins, mTOR and circadian rhythms
• How the Kaufmann Protocol approaches healthy ageing
• The science behind supplements including NMN, pterostilbene, astaxanthin, curcumin and carnosine
• Why sleep, stress and recovery remain the foundation before advanced interventions
• The future of longevity through peptides, exosomes and biologics
If you're interested in biological age, longevity science and optimising your health with evidence-based strategies, this episode provides a practical framework from one of the world's leading experts in cellular ageing.
