ApoB Explained: What Your LDL Test Doesn’t Tell You

For decades, LDL cholesterol has been the go-to metric for assessing heart disease risk. But growing research suggests there's a better predictor: ApoB. But is it a predictor in itself, or is it a marker of something even more important?

Apolipoprotein B (ApoB) is a protein found on all potentially harmful lipoprotein particles, like LDL, VLDL, and remnants. Because each particle carries one ApoB, it offers a direct count of the total number of atherogenic particles, something LDL cholesterol can’t do.

In this video, Dr. Bret Scher breaks down the key differences between LDL and ApoB, how metabolic health influences both, and why understanding the full picture is critical for preventing heart disease.

📌 What you’ll learn:

• Why ApoB is more predictive than LDL in metabolically unhealthy individuals
• The role of particle number vs. cholesterol content
• What LDL and ApoB each reveal — and where they fall short
• How metabolic dysfunction drives up ApoB and cardiovascular risk
• Why improving insulin sensitivity and inflammation matters more than chasing numbers

Whether you're managing your own heart health or guiding others, this video will help you interpret labs more clearly so you can focus on what really matters.
