Cold and heat exposure, morning sunlight, nature time, and screen time management.
Life purpose, gratitude practice, learning behaviors, volunteering, and spirituality.
Inspired by validated phenotypic aging models (Levine et al., 2018), Real Bio Age uses a questionnaire-based approach that evaluates lifestyle, health, and environmental factors associated with biological aging. Our assessment is complementary to clinical screening—providing actionable lifestyle insights without a blood draw.
Our methodology draws from published studies in JAMA, The Lancet, Nature Aging, Circulation, and other top journals. Every question traces to specific research findings. View our research
Scoring uses mortality hazard ratios from large-cohort epidemiological studies including UK Biobank (500,000+ participants) and the Framingham Heart Study.
Thresholds adjust based on your age bracket and biological sex. What's excellent at 60 differs from 25—our algorithms account for this automatically.
The Only Biological Age Assessment That Measures You AND Your Environment. Powered by 94 Research-Backed Questions Across 12 Health Domains.
Created by Advanced Learning Academy. Elite cognitive assessment and educational testing since 2015. Home of Real World IQ and Real Bio Age.
BioAge Score to the Day. 12-System Health Breakdown. Environmental Impact Analysis. Personalized Action Plan. Plus 52 Weeks of Weekly Health Intelligence—New Research, Discoveries, and Updates That Affect Your Biological Age, Delivered to Your Inbox Every Week.
Other tests give you a rounded number. We calculate your biological age to the exact year, month, and day. That means you can see measurable change in weeks, not years. When you retest, you know exactly how many days you gained or lost.
No other biological age test factors in where you live. We analyze 7 environmental factors for your specific ZIP code—air quality, safety, food access, exercise opportunities, healthcare access, housing quality, and commute stress—and show you exactly how many days your location is adding to or subtracting from your age.
For previous assessment takers only. If you purchased the Progress Tracker ($179), retests are already included at no extra cost for 12 months.

Screening Tool Disclaimer
Real Bio Age™ is a screening and estimation tool only, not a medical diagnostic test. Results are estimates based on phenotypic models, self-reported data, and public environmental factors.
Not a substitute for professional medical advice, diagnosis, or treatment. Consult a physician for clinical biological age assessment (e.g., blood epigenetic tests). This product has not been evaluated by the FDA. It is not intended to diagnose, treat, cure, or prevent any disease.
Accuracy depends on input quality. Repeat testing recommended for tracking trends over time. Your ZIP code and lifestyle data are processed securely and not shared with third parties.
Everything you need to know about the Real Bio Age assessment.
Two People. Same Birth Year. One Body Says 42. The Other Says 57. The Difference Is Environment, Habits, and Health—And Now You Can Measure All Three. Chronological age is simply how many years since you were born. Biological age reflects how old your body actually functions.
Real Bio Age contains 94 research-informed questions derived from peer-reviewed studies. While most competitors use just 10-20 generic questions, our comprehensive assessment covers all 12 health domains for a more thorough lifestyle evaluation. The test takes approximately 15-25 minutes to complete.
Real Bio Age analyzes 12 comprehensive health domains: Musculoskeletal, Cardiovascular, Metabolic & Gut, Cognitive & Sleep, Lifestyle & Social, Recovery & Resilience, Environmental, Meta-Perception, Physical Proxies, Metabolic & Glycation, Hormetic Stress, and Purpose & Mindset. Each domain is weighted based on peer-reviewed mortality research.
Real Bio Age is the ONLY biological age test that analyzes your ZIP code's environmental impact. We analyze 7 environmental factors—air quality, crime & safety, food access, exercise opportunities, healthcare access, housing quality, and commute stress—for 33,000+ U.S. ZIP codes—quantifying the impact to the exact day. Research shows your environment can add or subtract years from your biological age.
Unlike other tests that give vague estimates like "about 45 years old," Real Bio Age calculates your results with day-level precision. We tell you exactly: "45 years, 3 months, 17 days." This precision lets you track meaningful progress in weeks or months, not years—making lifestyle interventions measurable and motivating.
Real Bio Age draws on findings from peer-reviewed studies including UK Biobank (500,000+ participants), Framingham Heart Study, and PURE Study. Our methodology is age-stratified and sex-specific, meaning thresholds adjust based on your demographic profile. As a questionnaire-based tool, accuracy depends on honest, complete responses.
Real Bio Age was developed by Advanced Learning Academy, founded by Timothy Parker—Guinness World Records Puzzle Master, who has reached 180+ million people across 80+ countries. Parker has created thousands of original puzzles and brain assessments, and brings his expertise in algorithm design, pattern recognition, and psychometrics to the health assessment field. The assessment methodology was developed using peer-reviewed research from leading institutions.
Yes! Unlike chronological age, biological age is malleable and even reversible. Published research shows lifestyle interventions including diet, exercise, sleep optimization, and stress management can reverse biological aging by 2-8 years within months. Our report identifies your top 3 "age accelerators" with specific recommendations.
We recommend retaking every 2-3 months to track progress. As you implement lifestyle changes, your biological age should improve. The Full + 12-Month Tracking package ($179) includes unlimited retests for 12 months with 3-test progress tracking (Baseline / Previous / Latest)—letting you see exactly which interventions are working across all 12 domains.
No. Real Bio Age is an educational wellness tool, not a medical diagnostic. It does not diagnose, treat, or prevent any disease. While our assessment is based on peer-reviewed research, always consult healthcare professionals for medical advice and before making significant health changes.

Most people complete the 94-question assessment in 15-25 minutes, but there is no time limit. Your progress is automatically saved after every answer, so you can close the browser and come back anytime—tomorrow, next week, whenever you are ready. You will pick up exactly where you left off. We recommend taking your time and answering honestly for the most accurate results.
Yes. Real Bio Age uses sex-specific calculations because biological aging markers differ between males and females. Healthy ranges for metrics like blood pressure, fitness benchmarks, and various health indicators vary by sex. Our algorithm applies research-validated thresholds based on your biological sex.
Our algorithm is age-stratified for adults 18 and older. What's considered excellent fitness for a 70-year-old differs from a 30-year-old—our algorithm accounts for this with specific calibrations for different age brackets (20s, 30s, 40s, 50s, 60s, 70+). Each age band has research-appropriate thresholds.
Real Bio Age draws from peer-reviewed studies including UK Biobank (500,000+ participants), Framingham Heart Study (70+ years of data), PURE Study (180,000+ participants across 21 countries), and publications in JAMA, The Lancet, Nature Aging, and Circulation. View our full research bibliography.
