Where is your aging trajectory headed?

A free, educational estimate of how well your daily habits support a healthy aging trajectory. Biological age is the snapshot; pace of aging is the trend you can support.

Take the 2-minute quiz

Answer a few quick questions and get an educational read on your aging trajectory, plus what a real biological-age test (the kind used in longevity research) actually measures. It is for education only, not a diagnosis.

What you will get: a trajectory band and a read on the areas with the most room to strengthen support.

Educational, not a diagnosis

Biological Age Calculator

Answer a few quick questions to see how well your habits support a healthy aging trajectory. It takes about two minutes, and your answers stay on your device.

This calculator is for educational purposes only and is not medical advice, a diagnosis, or a measurement of your biological age. It estimates how well your current habits may support a healthy aging trajectory. Nutrient statements describe support for the normal structure and function of the body. Results may vary. Always consult your healthcare provider before starting any new wellness program.

How it works: Discover, Optimize, Verify

Discover where you stand, optimize the foundations that matter most, and verify your trend over time with a real test. Your result is a trajectory band, not a score to fear.

What the calculator looks at

Pace of aging

How quickly you recover and how your energy is trending, the everyday signals of your current rate of aging.

Cellular & mineral support

Signals tied to magnesium, electrolytes, and hydration that support normal cellular energy and function.

Inflammation & recovery

Diet quality, joint comfort, and recovery, the inputs behind a healthy inflammatory response.

Stress, sleep & focus

Sleep quality, stress load, and mental clarity, which shape how the body maintains and repairs itself.

Plus four more areas: metabolic and mitochondrial vitality, immune resilience, cumulative load, and movement, lifestyle, and exposure, for eight areas in all.

Your privacy

Your individual answers are not stored. The calculator scores your responses in your browser and, only if you ask for your full result by email, saves a short summary (your trajectory band and focus areas) so we can send it and keep you updated. We never sell your information, and you can unsubscribe anytime.

Common questions

Is this a biological age test?

No. It is an educational estimate based on your habits. It does not measure or diagnose your biological age, and it does not give you a number. It teaches what a real test measures.

Are my answers saved?

No. Your individual answers are not stored. Only a short summary is saved if you choose to have your full result emailed to you.

What is the difference between biological age and pace of aging?

Biological age is a snapshot of accumulated aging; pace of aging estimates how fast you are aging right now. The calculator focuses on the trend you can support.

What should I do with my result?

Use it to see which foundations to support, then, if you want a real measurement, learn what biological-age testing involves and consider re-checking your trend over time.

What your result means

Your result is one of three educational bands: a Supported trajectory, a Mixed trajectory, or an Opportunity-rich trajectory, plus the areas with the most room to support healthy aging. It maps each area to what a real biological-age test measures, so you know what to ask for next. It is a trend to support, never a diagnosis or a fixed verdict.

Strong evidence

Pace-of-aging measures are designed to reflect change within about three months, which is why supporting healthy habits and re-checking your trend is more useful than any single number.
