Your ring gives you one biological age, your watch gives you another, and the lab panel you ordered last spring lands somewhere else. It's hard to know which number to believe, or whether any of it is worth the money you're spending on it.
In this episode, Dr. Su talks with Ryan Smith, founder of TruDiagnostic, about how to sort signal from noise. Ryan explains that the most important thing to check in a biological age test is how well it predicts real health outcomes later in life. A clock that simply gets better at guessing your birthday tells you very little. DNA methylation clocks trained on long-term outcomes have the strongest research behind them so far, and they respond to the things we already know improve healthspan.
They also cover what early research is showing on GLP-1s and longevity, including a placebo-controlled trial where biological age markers improved in people who were overweight but not diabetic, and why there's still very little data on microdosing. Dr. Su raises one of the harder parts of longevity work, which is that the changes that matter most at the cellular level may be ones you never feel. Ryan shares a simple filter for the next supplement or device that shows up in your feed: look at who is investing in the data to prove it works.
