The New Science of Healthy Aging: The Longevity Tests You Actually Need

Olympic medalist turned health-tech founder Andrew Steele says the problem isn't you: it's that "normal" and "optimal" are two different things. In this episode, he breaks down how DNA, microbiome, and blood testing expose what's really behind your fatigue, brain fog, and bloating. And why one test, one time, will never tell you the full story.

WHAT YOU'LL LEARN

- Why small, consistent daily habits move the needle on longevity more than big lifestyle overhauls

- How the ACTN3 gene explains why "average" training and health advice doesn't work for everyone

- What DNA methylation is, and why taking more B vitamins can backfire if you have an MTHFR variant

- Why "normal" bloodwork isn't the same as optimal health

- How the PhenoAge biological age test measures how fast you're really aging

- Why bloating and brain fog in midlife women are often linked to the estrobolome and gut bacteria

- Why microbiome and blood testing needs to be repeated over time, not done once

- The best way to prepare for accurate blood and microbiome test results

- The three biomarkers Andrew recommends testing first: methylation, gut-brain axis, and ApoB

- Why wearables alone can't give you the full picture of your health

- How Stride is integrating oral microbiome testing and wearable data

- Why data and dashboards alone don't change behavior without human coaching

- What's inside Stride's ST01 liposomal multivitamin and why it's formulated around methylation
