EPISODE 166: SPERMIDINE & THE SCIENCE OF STAYING YOUNG, WITH LESLIE KENNY
Tue Nov 25 2025
What if aging isn't something we just have to accept?
This week, we dive into the fascinating world of spermidine, a naturally occurring molecule that might just be one of the most powerful longevity tools we have. Our guest, Leslie Kenny - founder of Oxford Healthspan and creator of Primeadine® - breaks it all down and shares how she has personally reversed doctors' diagnoses of lupus, rheumatoid arthritis, infertility, and a literal death sentence, later giving birth naturally at the age of 43. She now has a biological age nearly four decades younger than her chronological age, and has devoted her life to longevity research and sourcing Primeadine® from the longevity islands of Japan.
She explains:
How spermidine activates autophagy (your body's cellular cleanup system)
Why it's being studied for heart health, brain clarity, and healthy aging
What foods naturally contain spermidine, and when supplementation matters
The science behind Primeadine®, her spermidine brand backed by clinical research
Simple daily practices that help your cells act younger, even as you get older

From cutting-edge research to practical daily habits, this episode explores how we can extend not just our lifespan, but our healthspan. Could spermidine be the missing piece of the longevity puzzle?
