Apolipoprotein B (ApoB)

Apolipoprotein B (ApoB) is the protein embedded in every atherogenic (artery-damaging) lipoprotein particle — including LDL, VLDL, IDL, and Lp(a). Unlike standard LDL cholesterol which measures the cholesterol content inside LDL particles, ApoB counts the actual number of particles. This distinction matters because particle number — not cholesterol content — drives atherosclerosis.

Optimal Ranges

Clinical (NHS) Range

<130 mg/dL

mg/dL

Performance-Optimised Range

<90 mg/dL (longevity-optimised: <80 mg/dL)

mg/dL

The clinical range defines what is considered medically “normal” — broad enough to cover 95% of the population. The performance range reflects where research and clinical experience suggest most people feel and function at their best.

Why It Matters

Why ApoB matters for performance

ApoB is increasingly recognised as the single best predictor of cardiovascular risk — superior to LDL-C, total cholesterol, and even the TC:HDL ratio. The European Atherosclerosis Society recommends ApoB measurement for accurate cardiovascular risk assessment. Two people can have identical LDL-C numbers but very different ApoB levels (and very different risk) depending on their particle size distribution. For men focused on longevity, ApoB is the marker that bridges the gap between a standard cholesterol panel and actual arterial risk.

Symptoms

Signs your levels may be off

Low / Deficiency

  • Very low ApoB is generally not clinically significant
  • May indicate malabsorption or liver dysfunction in extreme cases

High / Excess

  • No direct symptoms — elevated ApoB is a silent risk factor
  • Associated with accelerated atherosclerosis
  • Increased risk of heart attack and stroke
  • Often accompanies metabolic syndrome and insulin resistance

Dietary Sources

Foods that support ApoB levels

Reduce refined carbohydrates (drive small dense LDL particles)Increase soluble fibre — oats, legumes, psylliumOmega-3 rich fish (salmon, mackerel, sardines)Nuts — almonds and walnuts specifically shown to reduce ApoBReplace saturated fat with monounsaturated (olive oil, avocado)

Supplementation

Evidence-based supplementation

Omega-3 fish oil (2-4g EPA+DHA daily) reduces ApoB-containing particle count by lowering VLDL production. Plant sterols and stanols (2g/day) block cholesterol absorption and can reduce ApoB by 5-10%. Berberine (1,000-1,500mg daily in divided doses) has LDL-lowering effects comparable to low-dose statins in some studies — it upregulates LDL receptors. Citrus bergamot extract (500-1,000mg daily) has emerging evidence for LDL particle reduction. For significantly elevated ApoB (>130), lifestyle plus pharmaceutical intervention (statins) may be warranted — discuss with your GP.
