Biomarkers
Evidence-graded guides to the biomarkers that matter for longevity — what each number means and what actually moves it.
- Lp(a) (lipoprotein(a))
The inherited heart-disease risk you can't lower — so you offset it. Whether to test (once), how to read your number through the unit trap, and what actually moves the risk.
- ApoB (apolipoprotein B)
The heart-disease number your cholesterol test leaves out — whether to test it, how to read it, and what actually lowers it, ranked honestly.
- Fasting insulin
The early-warning number your blood panel skips — it can run high for years while glucose still reads 'normal.' What's optimal (not just lab-normal), whether to test it, and what actually lowers it.
- Heart Rate Variability (HRV)
Why your number isn't your friend's number, how to read your own trend, what suppresses it, and what actually raises your baseline.
- Vitamin D
Read your 25(OH)D level, get the D3 dose to fix a deficiency, and see what supplementing actually does.
