Studies show that people with a biological age 5 years younger than their chronological age have a significantly lower risk of age-related diseases and live longer, healthier lives. The good news? You can improve your biological age through lifestyle changes!
Excellent! Your lifestyle choices are paying off. You're aging slower than average.
Good work! You're on the right track with healthy aging habits.
Normal range. Small improvements in lifestyle can make a big difference.
Time to take action. Focus on nutrition, exercise, and sleep quality.

Phenotypic age is one way of measuring your biological age - it tells you how well your body is aging compared to your chronological age. Unlike your calendar age, it reflects your actual cellular health and predicts mortality risk, disease risk, and physical function better than age alone. Learn more
This calculator uses the scientifically validated Levine formula published in the journal Aging (2018), based on analysis of 9,926 adults. It's the same formula used in longevity research and has been shown to be a strong predictor of healthspan and lifespan.
You need 9 biomarkers: Albumin, Creatinine, Glucose, CRP, Alkaline Phosphatase, WBC, Lymphocyte %, MCV, and RDW-CV. Most come from a standard Full Blood Count plus a basic metabolic panel. See full requirements
Yes! Phenotypic age is not fixed. Studies show improvements through lifestyle changes including nutrition, exercise, sleep, and stress management. Many people see improvements within 6-12 months. Get evidence-based tips
