Chronological age is simply how many years since you were born. Biological age reflects how old your body actually functions—factoring in lifestyle, genetics, environment, and health behaviors. Two people born the same year can have vastly different biological ages.
Real Bio Age uses 94 research-backed questions across 12 health domains, each weighted according to peer-reviewed mortality and morbidity studies from UK Biobank, Framingham Heart Study, PURE Study, and 200+ published research papers.
Where you live significantly impacts your biological age. We analyze 7 environmental factors: air quality, crime/safety, food access, exercise opportunities, healthcare access, housing quality, and commute stress.
Most online tests use 10-20 generic questions. Real Bio Age uses 94 questions with age-stratified and sex-specific scoring. We calculate your age to the DAY and incorporate real environmental data for your specific location.
Musculoskeletal, Cardiovascular, Metabolic & Gut, Cognitive & Sleep, Lifestyle & Social, Recovery, Environmental, Meta-Perception, Physical Proxies, Metabolic & Glycation, Hormetic Stress, and Purpose & Mindset.
Absolutely. Unlike chronological age, biological age is modifiable. Research shows lifestyle interventions can reverse biological aging by 2-8 years within months. Our report identifies your top 3 "age accelerators" with specific recommendations.
Most people complete the 94-question assessment in 12-18 minutes. We recommend taking your time and answering honestly for the most accurate results.
Your precise biological age (years, months, days), domain-by-domain breakdown, environmental impact analysis, top age accelerators and protectors, personalized recommendations, and a 12 months of weekly anti-aging and biological age updates.
Yes. We do not sell your personal information. Your assessment data is encrypted and used solely to generate your report. See our Privacy Policy for complete details.
We recommend retaking every 6-12 months to track progress. As you implement lifestyle changes, your biological age should improve. Tracking over time validates your efforts.
No. Real Bio Age is an educational wellness tool, not a medical diagnostic. It does not diagnose, treat, or prevent any disease. Always consult healthcare professionals for medical advice.
