Episode #315. What is ApoB and why should you care? In this latest instalment of our masterclass series, I’ve distilled the essential insights about apolipoprotein B (ApoB) into one informative episode. Join top experts including Dr Thomas Dayspring, Dr William Cromwell, Danny Lennon, Dr Alan Flanagan, and Dr Gil Carvalho as they unravel the significance of ApoB as a crucial marker of cardiovascular health. This episode provides a thorough understanding of why ApoB matters and how it impacts your health.

We unpack the essentials of ApoB, covering its role in cholesterol transport and why it's a key marker for heart disease risk. You'll learn how ApoB affects cardiovascular health, from the way it modifies LDL particles to its impact on atherosclerosis and longevity. We discuss the best ways to measure ApoB, its normal levels, and what causes it to rise. The episode also explores the relationship between ApoB and saturated fats, and why it's a more reliable risk marker than LDL cholesterol. By the end, you'll have a clear understanding of why ApoB matters for your heart health and how it can help guide better health choices.
