#420: Spermidine UNLOCKED: Reverse Aging, Boost Immunity & Thrive After 40 With Leslie Kenny

Today, I'm joined by the inspiring Leslie Kenny, Oxford-based longevity expert and a living example of turning adversity into vitality. After being told at 39 that she had lupus, rheumatoid arthritis, and just five years to live, Leslie defiantly forged a new path—reversing her diagnoses, restoring her thyroid health, and even welcoming a healthy baby girl at 43. Her story is a testament to the power of questioning the status quo, honoring the wisdom within our bodies, and refusing to accept decline as inevitable. Leslie has a generous offer for you, when you visit oxfordhealthspan.com/BIONAT20 and use code BIONAT20 at checkout you'll get 20% off.
