Chronologically, you get 1 year older every year. But how old are you getting biologically?
In order to optimize longevity, you need to understand biological aging.
With all the different longevity and biological aging tests, it can be difficult to understand where to start.
Fortunately, we got Ryan Smith from Tru Diagnostic on todays episode to guide you on all things longevity and biological aging.
In this episode, Ryan highlights the different biological aging tests and which one is the most accurate.
He also gives helpful tips on how to reduce your pace of aging, and how that’s important for your overall lifespan.
Ryan Smith is founder of TruDiagnostic, which has created the largest private epigenetic database in the world with over 25,000 patients tested. From this dataset, they have created many new algorithms to interpret methylation data including algorithms to predict inflammatory markers, disease diagnosis, telomere length, aging pace, immune cell subsets, cellular replication, and more.
