Episode notes

INSIGHT

It's Not Too Late To Start Improving Health

Age alone should not stop anyone from improving health because interventions can work when started late.
Studies (e.g., rapamycin in old animals) show functional declines can be delayed or even improved when treatment starts late.

INSIGHT

FDA Cares About Endpoints, Not Disease Labels

FDA approval depends on proving safety and meaningful benefit, not on labeling aging as a disease.
Developers can choose many clinical endpoints to show improved quality or quantity of life for approval.

INSIGHT

Resveratrol Failed To Prove Longevity Benefits

Resveratrol does not extend lifespan across studies and meta-analyses show no net longevity benefit.
Publication bias inflates positives, making it likely resveratrol lacks meaningful lifespan effects.

I spent the first few decades of my career doing scientific research into the biology of aging, trying to understand the finer details of how humans age in order to facilitate translational interventions that promote healthspan and improve quality of life. Now I want to take some of that knowledge out of the lab and into the hands of people who can really use it.On this podcast I talk about all things aging and healthspan, from supplements and nutrition to the latest discoveries in longevity research. My goal is to lift the veil on the geroscience and longevity world and help you apply what we know to your own personal health trajectory. I care about quality science and will always be honest about what I don't know. I hope you'll find these episodes helpful!
