The longevity biomarker map: VO2 max, ApoB, CGM, DEXA and HRV.

Some biomarkers are clinically actionable, some are performance markers and some are exploratory signals.

Simple answer

The best longevity biomarker map separates validated clinical risk markers from fitness measures and exploratory consumer metrics. They should not all be treated equally.

What the source says

Some markers, such as ApoB, connect to established clinical risk pathways.
Fitness and body-composition measures can be meaningful but require context.
Wearables and consumer metrics are useful for trends but can be noisy.

What it does not prove

It does not prove every metric needs tracking.
It does not prove a short-term change matters.
It does not turn consumer data into a diagnosis.

Practical takeaway

Prioritize markers with strong outcome links and clear action pathways before chasing exotic scores.

Ask a qualified clinician if

a marker is abnormal, trend direction is unclear or you plan to change medical treatment.

What to watch next

Guideline updates for cardiovascular and metabolic risk.
Better validation of wearable-derived metrics.
Studies tying biomarker changes to outcomes.

FAQs

Which markers are most actionable?

Clinically established risk markers and fitness measures with clear interpretation tend to be more actionable than proprietary age scores.

Is more tracking always better?

No. More data can help, but it can also create noise and false confidence.

What is biological age?

Biological age is an attempt to estimate health or aging state, not a second birth certificate.

What actually works in longevity before experimental interventions?

The strongest foundation is not exotic: fitness, blood pressure, lipids, sleep, smoking avoidance, nutrition and preventive care.
