The Research
Why it matters more than your birthday — and what you can do about it.
Chronological age is the number on your birthday cake. Biological age is how old your body actually is at the cellular level.
Same birthday · Age 50
Person A
Active, good sleep, low stress

Person B
Sedentary, poor sleep, high stress

BioAge™
16-year difference. Same birthday.
Twin studies show only 20% of aging is genetic. The rest — diet, sleep, stress, exercise — is up to you.

Your genes have switches
Epigenetics determines which genes are on or off. Lifestyle factors — diet, sleep, stress — can flip these switches.
Aging leaves a signature
DNA methylation patterns change predictably as we age. By measuring them, scientists can estimate biological age with high accuracy.
It's reversible
Unlike genetic mutations, epigenetic changes can be reversed. Targeted interventions can make your cells younger at the molecular level.
Together, they determine your biological age.
Grounded in peer-reviewed research from leading journals.
Epigenetic Clocks & Biological Age
Nature Reviews Genetics, 2018
DNA methylation patterns can predict biological age with remarkable accuracy. The Horvath Clock correlates with mortality risk better than chronological age.
Lifestyle Interventions & Age Reversal
Aging Cell, 2021
An 8-week program of diet, sleep, exercise, and stress management reduced biological age by an average of 3.23 years.
Genetics vs Environment
JAMA Internal Medicine, 2020
Twin studies show only 20–25% of lifespan variation is genetic. The remaining 75–80% is influenced by modifiable factors.
Inflammation & Accelerated Aging
Nature Medicine, 2019
Chronic low-grade inflammation is a hallmark of biological aging and precedes most age-related diseases by years.
Research shows targeted lifestyle changes can measurably reduce biological age.
