    The 9 Biomarkers That Reveal Your True Age

    Based on Dr. Morgan Levine's Phenotypic Age research, we analyze these clinically validated markers to calculate your biological age.

    Albumin

    Liver function & nutrition status

    Creatinine

    Kidney function indicator

    Glucose

    Metabolic & energy health

    C-Reactive Protein (CRP)

    Inflammation marker

    Lymphocyte %

    Immune system health

    Mean Corpuscular Volume (MCV)

    Red blood cell size

    Red Cell Distribution Width (RDW)

    Blood cell variation

    Alkaline Phosphatase (ALP)

    Liver & bone health

    White Blood Cell Count (WBC)

    Overall immune function

    Chronological Age vs. Biological Age

    Your birthday tells you one story, but your blood tells another. Understanding the difference is the first step to optimizing your healthspan.

    Chronological Age

    Simply how many years since you were born. It's a fixed number that increases by one every year, regardless of your lifestyle or health choices.

    • Cannot be changed
    • Same for everyone born on your date
    • Doesn't reflect health status

    Biological Age

    How old your body actually is based on biomarkers. A 50-year-old with excellent health markers might have a biological age of 42, while poor habits could push it to 58.

    • Can be improved with lifestyle changes
    • Reflects your actual health status
    • Predicts mortality & disease risk

    Frequently Asked Questions

    What is biological age?

    Biological age measures how old your body actually is based on biomarkers, as opposed to chronological age which is simply how many years you've been alive. Someone who is 50 years old chronologically might have a biological age of 45 if they're in excellent health, or 55 if certain health markers are suboptimal.

    How is Phenotypic Age calculated?

    Phenotypic Age is calculated using 9 key biomarkers from a standard blood test, based on Dr. Morgan Levine's research published in the journal Aging. The algorithm analyzes Albumin, Creatinine, Glucose, C-Reactive Protein, Lymphocyte %, MCV, RDW, Alkaline Phosphatase, and White Blood Cell Count to estimate biological age.

    Can I lower my biological age?

    Yes! Research shows that lifestyle interventions like improved nutrition, regular exercise, better sleep, and stress management can reduce biological age. By tracking your biomarkers over time, you can see how your interventions are working and adjust accordingly.

    What blood test do I need?

    A standard Complete Blood Count (CBC) and Comprehensive Metabolic Panel (CMP) from any lab (Quest, LabCorp, etc.) will include most of the biomarkers needed. We also accept results from InsideTracker, Function Health, and international labs using SI units.
