What is a normal ApoB level?

Most laboratories report 55–140 mg/dL as normal. Varies by laboratory; women's upper bound is often quoted slightly lower at ~130 mg/dL.

How do I lower my ApoB?

If ApoB is above 100 mg/dL, treat that as a conversation with a doctor rather than a diet project — pharmacological options move it far further than diet alone. Cut saturated fat to under 7% of calories. This is the single largest dietary lever on ApoB. Add 5–10 g/day of viscous soluble fibre (oats, psyllium, beans). Expect a 5–10% reduction. Address insulin resistance if present — ApoB tends to fall with it. Retest at 8–12 weeks. Lipid changes need that long to stabilise.

Q: What is an optimal ApoB level?

< 80 mg/dL. Preventive-cardiology convention for primary prevention. Below 60 mg/dL is the target where atherosclerotic disease is already established or risk is high.

Also reported as: Apolipoprotein B · ApoB-100

The number of atherogenic lipoprotein particles in circulation — one ApoB molecule sits on every LDL, VLDL, IDL and Lp(a) particle, so ApoB is a direct particle count.

Why it matters

Atherosclerosis is driven by how many particles cross the arterial wall, not how much cholesterol those particles happen to carry. Two people with identical LDL-C can differ substantially in particle number, and it is the particle number that tracks with risk. ApoB outperforms LDL-C as a predictor in every head-to-head comparison, which is why preventive cardiology has increasingly moved to it.

What raises it

Saturated fat intake, particularly from dairy fat and processed meat
Insulin resistance and visceral adiposity
Familial hypercholesterolaemia and other genetic lipid disorders
Hypothyroidism
Nephrotic syndrome and cholestatic liver disease

What lowers it

Statins, ezetimibe and PCSK9 inhibitors
Soluble fibre — 5–10 g/day of viscous fibre
Replacing saturated with monounsaturated and polyunsaturated fat
Weight loss where visceral fat is the driver

What makes a single reading misleading

ApoB does not require fasting, unlike a standard lipid panel with calculated LDL-C.
A single reading can vary by 5–10% from biological variation alone. Trends matter more than one number.
Acute illness temporarily lowers lipid levels; wait several weeks after an infection.
