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
