Is ApoB useful for longevity?

ApoB (Apolipoprotein B) is a core component of atherogenic lipoproteins and a strong predictor of cardiovascular events – and thus indirectly of longevity. Evidence shows that ApoB measures the number of particles that can clog arteries, often outperforming LDL cholesterol in risk prediction. However, the provided context does not directly address ApoB. The human evidence for ApoB as a risk marker is strong (prospective cohorts, Mendelian randomization), but its link to longevity is indirect – lowering ApoB reduces heart attack risk, which can extend lifespan. Consumer tests often do not measure ApoB directly; they may use calculated estimates. Caveat: A single biomarker cannot predict overall lifespan – lifestyle, inflammation, and other factors matter. For reliable assessment, a fasting lipid panel including ApoB is recommended.
