Matt Kaeberlein's New Longevity Science Podcast / Youtube Channel (May, 2026)
Matt Kaeberlein and Brian Kennedy introduced LinAge, a second‑generation mortality‑risk clock built on standard clinical chemistry panels, positioning it as a reproducible alternative to first‑generation DNA‑methylation clocks. They highlighted the technical instability and lack of clinical actionability of epigenetic clocks, arguing that LinAge’s principal‑component framework lets physicians model the impact of correcting specific biomarkers. The discussion also debunked the long‑standing belief that blood NAD+ declines with age, shifting focus toward tissue‑specific interventions such as spermidine‑induced autophagy and alpha‑ketoglutarate modulation. Finally, they offered a tiered protocol recommending spermidine supplementation and targeted lipid‑lowering therapies for individuals with elevated LinAge risk components.
