Apolipoprotein B (ApoB)

Advanced wellness

also apo b, apolipoprotein b-100

What it isApoB is the structural protein on the surface of every atherogenic lipoprotein particle — one ApoB molecule per particle. Measuring ApoB therefore gives a direct count of atherogenic particles.

DoesEach ApoB-containing particle is a candidate to deposit cholesterol into the artery wall. The count of these particles, not the cholesterol they carry, drives atherosclerosis.

GoodLow ApoB means few atherogenic particles in circulation and is the single strongest lipid predictor of low cardiovascular risk.

BadElevated ApoB causally drives atherosclerosis, heart attack, and stroke — even when LDL-C looks reassuring (a common discordance in metabolic syndrome).

Standard

<90 mg/dL desirable; <80 borderline; ≥110 high.

Optimal

30–60 mg/dL (lower is good)

Modifiers

Genetics dominate baseline; rises with insulin resistance, saturated fat, and weight gain.

How to optimize

Lifestyle: Zone 2 cardio, resistance training, weight loss, smoking cessation.
Diet: Cut saturated fat (full-fat dairy, fatty red meat, butter, coconut oil); add soluble fiber (psyllium 10g/day, oats, beans); olive oil and nuts; soy protein.
Supplements: Plant sterols (2g/day), psyllium (10g/day), bergamot extract (500mg 2×/day), berberine (500mg 3×/day), red yeast rice (with monitoring).
Peptides: —
Drugs: Statins (the cornerstone), ezetimibe, bempedoic acid, PCSK9 inhibitors (alirocumab, evolocumab), inclisiran.
