Personal aging evaluation

How well are you aging?

Enter what you know — basic biometrics, lifestyle, optional bloodwork. We estimate a biological age and break down what's adding or subtracting years. Educational only; not medical advice.

Demographics

Chronological age years Sex assigned at birth Height cm Weight kg Ethnicity / ancestry (optional, affects baseline risk) Country of residence (life-expectancy context)

Lifestyle

Smoking status Alcohol standard drinks / week Exercise moderate-vigorous min / week Strength training sessions / week Sleep average hours / night Daily steps average Diet quality (Mediterranean-style scale, 1–10)

10 = vegetables/fish/olive oil/legumes daily, ~no ultra-processed; 1 = mostly ultra-processed. Stress level (1 = serene, 10 = chronic high)

Social engagement (1 = isolated, 10 = strong network)

Existing conditions (click any that apply)

Optional biomarkers — sharpens the estimate; leave blank if unknown

Resting heart rate bpm Systolic blood pressure mmHg Fasting glucose mg/dL HbA1c % LDL cholesterol mg/dL HDL cholesterol mg/dL hs-CRP mg/L (inflammation) VO₂ max mL/kg/min Family history (longevity vs early disease in 1st-degree relatives)

Your inputs are processed securely by the Gyotta longevity engine — an automated cloud pipeline that runs your data through our composite of widely-cited longevity and cardiometabolic literature. Educational only; not a diagnostic instrument.

Lab-grade biological age

PhenoAge — when you have a blood panel.

PhenoAge (Levine et al., Aging, 2018) is a published biological-age estimator built from 9 standard blood markers plus chronological age, validated against mortality outcomes in NHANES. Enter your most recent values for a publication-grade estimate.

Units: US (mg/dL) SI (mmol/L)

Chronological age years Albumin g/dL · normal 3.5–5.0 Creatinine mg/dL · normal 0.6–1.2 Fasting glucose mg/dL · normal 70–100 CRP (hs-CRP) mg/L · normal <1.0 Lymphocyte percent % of WBC · normal 20–40 MCV (mean corpuscular volume) fL · normal 80–100 RDW (red-cell distribution width) % · normal 11.5–14.5 Alkaline phosphatase (ALP) U/L · normal 40–129 White blood cell count ×10³/μL · normal 4.0–11.0

Your panel is processed securely by the Gyotta longevity engine using the published Levine et al. PhenoAge model. Most modern blood panels include all 9 markers (CBC + comprehensive metabolic panel + hs-CRP). PhenoAge is well-validated for population-level mortality prediction but is one estimate among many — track movement over repeated panels for actionable signal, not a single reading.
