Show notes

In this 123rd episode of Sober Head Podcast, Dr. Esra Çavuşoğlu, PhD welcomes Prof. Brian Kennedy. In this episode, leading geroscientist Prof. Brian Kennedy explains how longevity science can move beyond academic laboratories and into responsible, real-world clinical practice. We explore mTOR and rapamycin, CA-AKG, biological age testing, ovarian aging, menopause-delaying research, peptides, gene therapies, and the growing longevity clinic industry.

Dr. Kennedy warns that combining too many supplements may unintentionally over-suppress essential cellular pathways. He also explains why many commercial biological age tests remain inconsistent, why personalized measurement matters, and how peptides could become some of the most important longevity medicines of the future.

We also discuss Singapore’s $300 million healthy longevity initiative and why healthcare must shift from treating disease to preserving health and performance throughout life.
