What is ApoB, and should you test it?

Verdict on whether lowering ApoB lowers the risk of heart disease: Not enough evidence. ApoB, the count of atherogenic particles, predicts cardiovascular risk better than standard LDL-C and is worth measuring with your doctor rather than relying on a basic cholesterol panel. How low to push it, how early, and how much to rely on diet versus drugs are the open questions. Targets and any medication belong with your physician.

Best for:
adults who want to check heart risk with their doctor beyond a basic cholesterol panel.

6 risks to check before you start

  1. Nothing here is medical advice. Any decision to test ApoB, read a result, or start or stop lipid-lowering medication belongs with your doctor.
  2. The most aggressive targets (childhood-low ApoB, around 20-40 mg/dL) are clinical, physician-supervised positions (Peter Attia). So is the use of statins, ezetimibe, bempedoic acid and PCSK9 inhibitors; none of it is a self-prescribed protocol.
  3. ApoB is not always on a standard cholesterol panel, so you may need to ask for advanced lipid testing through a doctor or lab (Mark Hyman).
  4. Diet alone often falls short of optimal ApoB targets, so lifestyle change may need medical management alongside it, which only a doctor can direct (Peter Attia).
  5. A negative coronary artery calcium (CAC) score does not rule out heart risk in high-risk people (Peter Attia). Don't treat a clean calcium scan as permission to ignore high ApoB.
  6. Statins can cause side effects: muscle aches, raised liver enzymes, and more insulin resistance at high doses (Peter Attia). That is another reason drug-based ApoB lowering should be guided by a doctor.
