Did you know that blood cholesterol levels are influenced by far more than just the foods we eat?

Are you eager to know how to assess healthspan using your own body's data? 

This episode of Longevity by Design is an Ask Me Anything between Dr. Gil Blander and Ashley Reaver. We gathered frequently asked questions from the Longevity by Design audience and discussed topics fundamental to longevity. 

Ashley Reaver begins the conversation with a deep dive into cholesterol—including the relationship between dietary cholesterol and blood cholesterol, the two most impactful nutrients on our blood cholesterol levels, how to navigate a family history of high cholesterol, and much more. 

Dr. Blander then answers questions about health metrics, explaining why VO2max is one of the best markers to assess heart health. He also discusses other markers of healthspan, the value of quality sleep, and the latest science on NAD+ precursors, including NMR and NM. Timestamps:
