Eliminate chronic irritants, restore gut integrity, and optimize immune balance.

In engineering terms, chronic inflammation is thermal load plus signal interference. It raises the baseline stress on every subsystem and distorts the very feedback signals you use to steer the machine.

This is why an elevated inflammatory dial produces nonlinear resistance: you pull the right levers on other dials and the expected gains simply do not arrive. The drivers are usually unglamorous and long-standing — visceral fat, accumulated sleep debt, oral inflammation, training load mismatch, gut integrity problems and alcohol.

The inflammatory dial is one of eight that make up your Longevity Score, and carries 12% of the composite. It is scored from 5 biomarkers against book-based scoring ranges rather than standard clinical cut-offs. These ranges are not a diagnosis or an individual treatment target.

Biomarkers scored in this dial

You do not need all of them. Blank values are excluded from scoring, never counted as zero. The markers tagged short-form input appear in the calculator's short form; this is not a recommendation to obtain tests.

hs-CRP Optimal < 1 mg/Lshort-form input
The book-aligned calculator scoring range is <1 mg/L. hs-CRP is nonspecific and can rise with illness or injury. Values above 10 mg/L usually need repeat testing when you are well before they are interpreted; discuss your result with your clinician.
Lymphocyte : Monocyte Ratio Optimal ≥ 4
Calculate from absolute lymphocyte count divided by absolute monocyte count in matching units. If the monocyte count is zero or unavailable, ask the lab for help. Discuss interpretation with your clinician.
Evidence basis: Wu et al. (International Journal of Cardiology Cardiovascular Risk and Prevention, 2025), analysing 1,518 NHANES participants over a median 150-month follow-up, found an L-shaped relationship between the lymphocyte-to-monocyte ratio and mortality — a lower ratio was independently associated with both all-cause and cardiovascular death. The study supports the direction this marker is scored in (lower is worse) rather than validating 4.0 as an exact breakpoint, which is why it is scored as a secondary, lower-weighted input.
Ferritin Optimal 40–100 ng/mL
U-shaped scoring (gender-adjusted). Men: optimal 50–100; Women: 30–80 ng/mL. Ranges shown are approximate midpoint — actual scoring is sex-specific. Too low = deficiency; too high = iron overload / inflammation.
WBC Count Optimal 3.5–6 ×10³/µL
Optimal 3.5–6.0. Chronically elevated WBC reflects systemic immune activation.
Uric Acid Optimal 2.5–5 mg/dL
Optimal <5.0 mg/dL. Upstream driver of metabolic inflammation and endothelial dysfunction.

How fast each marker actually responds

Markers move on very different timescales, and treating a slow one as a steering signal is the most common way people conclude that nothing is working. Steer with the fast signals; audit with the slow ones.

Acute spikes hours to days
infection, injury, hard training, poor sleep, alcohol
Systemic baseline weeks to months

Downstream damage years

Practical rule. A single elevated hs-CRP is not a verdict. Repeat it under stable conditions, then treat it as a systems troubleshooting problem rather than a diagnosis.

How this dial interacts with the others

No dial moves alone. If progress here has stalled, the cause is often sitting in one of these:

Assessment inputs to discuss

These are inputs for the assessment, not tests everyone needs. Discuss with your clinician which, if any, are appropriate and whether existing results can be used.

High-sensitivity CRP can measure lower concentrations than standard CRP, which may not reliably measure low values. Results can rise with infection, injury or other inflammation and need clinical interpretation.

hs-CRP (High-Sensitivity C-Reactive Protein) Assessment input
The calculator scores hs-CRP below 1 mg/L in its best range. A result above 10 mg/L can reflect acute inflammation or other causes; discuss whether to repeat it when well with your clinician.
Discussion: Discuss whether hs-CRP testing is appropriate and how to prepare with your clinician and lab
Homocysteine Additional input
Context only — not scored. Homocysteine is not a primary screening target; interpretation depends on clinical context, including kidney function and vitamin status.
Discussion: Discuss whether testing is appropriate and confirm preparation with your clinician and lab
Ferritin Assessment input
U-shaped optimal. Too low = iron deficiency; too high = inflammation or iron overload. Men optimal 50–100, women 30–80 ng/mL — both ends matter.
Discussion: Discuss whether testing is appropriate with your clinician and laboratory
Uric Acid Additional input
Chronic elevation drives endothelial dysfunction and gout. Often elevated with high fructose intake. Optimal <5.5 mg/dL for longevity.
Discussion: Discuss whether testing is appropriate with your clinician and laboratory

When to retest

Retest hs-CRP at 8 weeks (responds relatively quickly to lifestyle changes). Full panel at 12 weeks.

Frequently asked questions

What is biological age?

Chronological age counts birthdays. Biological age estimates how old your body appears to be functioning, based on measurable biomarkers. Two people born the same year can differ by a decade or more in vascular stiffness, insulin signalling or cardiorespiratory fitness. Biological age makes that gap explicit — and unlike your birthday, it can move in either direction.

How is the Longevity Score calculated?

Each biomarker you enter is scored against longevity-optimised reference ranges and grouped into one of eight dials. Every dial produces its own biological age, and those are combined using fixed weights into a single composite, then expressed as a Longevity Score from 0 to 100. The weighting reflects how strongly each system predicts healthspan: structural and vascular carry the most, hormonal the least.

Do I need all 53 biomarkers?

No. The short form contains a subset of scoring inputs plus context-only fields, and you can leave any of them blank. It is not a recommendation to obtain tests. Missing values are excluded from the calculation — never treated as zero or as 'normal'. A dial with no scored data is dropped entirely and the remaining weights renormalise.

What can I measure without a blood test?

Some inputs can be measured without bloodwork. Blood pressure needs a home cuff and waist-to-height needs a tape measure. Wearable estimates vary; the floor-based sitting-rising test carries a fall risk and should only be attempted if safe.

Is this an anti-aging calculator? Is it a healthspan calculator?

Both terms describe what this tool does, and which one fits depends on what you are asking. "Anti-aging" is the term most people search, and loosely means anything aimed at slowing or reversing age-related decline — this tool fits that description if you score your dials and act on what you find. "Healthspan calculator" is the more precise term: healthspan is the number of years lived without serious chronic disease or disability, and that cannot be measured directly, so this tool scores eight systems that each function as an early-warning proxy for it. Either way, the method is the same: real biomarkers, published thresholds, no vanity-metric framing.

Why don't you have a quick quiz that skips biomarkers entirely?

Several popular tools ask only about habits — exercise days, sleep hours, smoking, diet quality — and return a single precise-looking age. We looked at the research behind that approach and chose not to build it. Published studies do show real, individually-measured links between specific habits and epigenetic age acceleration, but those effect sizes come from different study populations, different DNA-methylation clocks and different measurement units. Adding them together into one number is not something the underlying research actually supports — it produces a precise-looking result built on an imprecise method. Our dials use direct physiological measurements instead: a real blood pressure reading, a real VO₂ max, a real ApoB value. Several dials score from home-measurable data alone with no quiz-guessing involved — see what you can measure without a blood test, above.

Why are your 'optimal' ranges stricter than my lab's normal range?

Standard reference ranges describe what is common in a general population, which now includes a great deal of metabolic dysfunction. They are tuned to flag disease, not to identify what is optimal for a long healthspan. A fasting insulin of 20 µIU/mL sits inside most labs' normal range and is strongly associated with insulin resistance. This tool uses longevity-optimised thresholds instead, so a flag here means room for optimisation — not a diagnosis.
