Cardiometabolic
Health Score

A scoring system that reads eight of the most clinically meaningful cardiometabolic markers against functional optimal ranges, not the conventional lab ranges built on a sick population average. The calculator produces a composite 0 to 100 score, identifies which markers are dragging you down, and explains exactly what each one means.

Why these eight markers.

Most cardiometabolic risk assessments lean on total cholesterol and LDL. That framework is incomplete and often misleading. These eight markers, weighted correctly, give a real picture of what is driving risk at the metabolic, inflammatory, and hormonal level.

01TG:HDL RatioOptimal: 0 to 1.5  20%
The single strongest predictor of insulin resistance and cardiovascular event risk. Stronger than LDL in isolation. A ratio under 1.5 signals metabolic efficiency. Above 3.0 signals significant insulin resistance regardless of what the lipid panel looks like in isolation.
02Fasting InsulinOptimal: 2 to 5 µIU/mL  20%
Fasting insulin is the earliest detectable signal of insulin resistance, often appearing years before blood glucose or HbA1c becomes abnormal. Conventional labs flag over 25. Functional medicine targets under 5. The gap between those two numbers is where metabolic disease develops silently.
03hs-CRPOptimal: 0 to 1 mg/L  15%
hs-CRP is the most practical marker of systemic inflammation, the common denominator behind heart disease, stroke, and accelerated aging. Under 1.0 is optimal. Between 1 and 3 is moderate risk. Over 3 is high risk for cardiovascular events. Elevated CRP without a known infection is a signal that something is driving chronic inflammation.
04T:E RatioOptimal: 20 to 40  15%
For men, the ratio of testosterone to estradiol matters more than either value in isolation. A low ratio indicates aromatization and estrogen dominance. A very high ratio can mean suppressed estradiol, which is also harmful to bone, mood, and libido. Optimal is between 20 and 40 when testosterone is in ng/dL and estradiol is in pg/mL.
05HomocysteineOptimal: 4 to 8 µmol/L  10%
Homocysteine is a byproduct of methionine metabolism. When B12, folate, or B6 are insufficient, or when MTHFR variants are present, homocysteine accumulates and damages the vascular endothelium. Optimal is under 8. Conventional labs flag over 15, but vascular damage begins above 8.
06HbA1cOptimal: 4.8 to 5.2%  8%
HbA1c reflects average glucose over the previous 90 days. Optimal is 4.8 to 5.2 percent. The conventional diabetic cutoff is 6.5, but metabolic damage accelerates above 5.3. HbA1c alone can miss insulin resistance, which is why fasting insulin carries more weight, but together they give a complete metabolic picture.
07FerritinOptimal: 100 to 200 ng/mL  7%
Ferritin is the iron storage protein and a direct input into ATP production and oxygen transport. Conventional labs accept 30 to 400 as normal, which is absurd. Below 80 and you cannot produce energy efficiently. Above 250 and you have storage iron accumulating in tissues, which drives oxidative stress and cardiovascular inflammation.
08Free T3Optimal: 3.2 to 4.2 pg/mL  5%
Free T3 is the active thyroid hormone that actually drives metabolic rate at the cellular level. Checking only TSH can completely miss a conversion issue where T4 is adequate but T3 is low, leaving you metabolically slow, cold, and fatigued despite normal-looking thyroid labs. Most conventional ranges go down to 2.0, which is not a healthy floor.

How the Scoring Works

Each marker is scored from 0 to 100 using piecewise linear interpolation between anchor points defined by functional optimal ranges. The anchors were selected to reflect the clinical evidence on cardiometabolic risk, not conventional lab reference ranges.

The composite score is a weighted sum of the individual marker scores. TG:HDL and fasting insulin carry the highest weight at 20 percent each because they are the strongest predictors of insulin resistance and cardiovascular risk. hs-CRP and the testosterone to estradiol ratio carry 15 percent each. Homocysteine carries 10 percent. HbA1c, ferritin, and Free T3 round out the remaining 20 percent.

A score of 85 or above on any individual marker places it in the optimal band. Between 60 and 84 is suboptimal. Below 60 needs attention. The composite score maps to four bands: Elite (90 to 100), Strong (75 to 89), Needs Work (50 to 74), and At Risk (below 50).

This tool is educational. It does not constitute medical advice, diagnosis, or treatment. A complete cardiometabolic assessment requires a full panel reviewed in clinical context by a qualified practitioner.
