Biological age score
See your phenotypic age calculated from 9 biomarkers. Compare it to your chronological age and track it over every lab upload.
Biological Age Intelligence
Know your biological age.
Take control of how you age.
MELLOW uses AI and your lab results to calculate your true biological age — then connects you with a provider who can help you improve it.
Not for emergency care. MELLOW is a wellness platform, not a medical device. Learn more about your data →

How MELLOW works
Three steps to understanding your biology
1
Upload your labs
Use the MELLOW mobile app to photograph or upload your standard blood test results. We extract 9 biomarkers automatically.
2
Get your BioAge score
Our AI calculates your Levine phenotypic age — a research-validated measure of how fast your body is actually ageing — and shows domain scores for cardiovascular, metabolic, and mental health.
3
Work with a provider
Connect with a MELLOW-certified provider who reviews your results, builds a personalised care plan, and tracks your progress over time.
For patients
Your health journey — visible, trackable, actionable.
Everything you need to understand and improve your biological age, in one place.
Health trend charts
Visualise biological age, glucose, and inflammation (CRP) trends across every test. Watch your numbers move in the right direction.
Personalised care plans
Your provider reviews your results and pushes a tailored diet, exercise, and supplement plan directly to your dashboard.
Secure provider messaging
Message your care team, view clinical notes, book appointments, and join video consultations — all from the patient portal.
Why MELLOW is different
Beyond a single age score.
Most biological age calculators stop at one number. MELLOW builds a whole-person longevity picture across the systems that actually drive how you age — with deep microbiome science as the differentiator that sets us apart from standard BioAge tools.
Cardiovascular
Heart and vascular aging indicators tracked over time.
Metabolic
Glucose regulation, weight, and insulin-sensitivity signals.
Mental wellness
Stress, sleep, and cognitive-resilience factors.
Fitness
Physical activity and functional-capacity scoring.
Nutrition
Diet quality and nutritional-status markers.
Microbiome science
Backed by the MELLOW Consortium's gut-health research program.
For providers
A clinical dashboard built for modern wellness medicine.
- Live patient roster with risk stratification and BioAge trends across your entire panel.
- Care plan builder — push diet, exercise, meditation, and medication plans to patients instantly.
- AI-generated clinical insights — review and authorise recommendations with one click.
- Appointment booking, secure messaging, and teleconsultation video rooms built in.
- Clinical visits, diagnoses, and lab report history all in one place — HIPAA-ready audit logging included.
For hospitals & wellness centres
Manage your entire clinical team from one portal.
Designed for hospitals, wellness centres, gyms, yoga studios, and dietitian practices.
Multi-location management
Add locations, assign providers to branches, and manage your full team. White-label the portal with your own brand colours and logo.
Schedule management
Set provider availability week by week. Patients book from live slots. Appointments appear on provider and hospital calendars in real time.
Population analytics
High-risk patient counts, BioAge gap distributions, biomarker averages, and risk breakdowns across your entire network.
Role-based access control
Providers access only their own patients. Hospital admins see aggregate data. Superadmins manage all hospitals. No cross-contamination.
MELLOW Research Consortium
Advancing the science of healthy aging.
Powered by the MELLOW Consortium and academic collaborators, MELLOW supports a growing network of longevity research programs that distinguish our platform from commercial calculators.
The MELLOW longevity roadmap
Where biological age intelligence is heading.
We are expanding the MELLOW framework with new domain-specific aging scores, powered by emerging biomarker categories and AI.
Gut
Gut Permeability Age
Leaky-gut assessment and microbiome aging score.
Gut
Microbiome Age
Microbiome diversity and composition-based aging.
Immune
Inflammation Age
Multi-marker inflammaging assessment.
Brain
Cognitive Age
Neurological biomarker-based brain aging score.
Epigenetics
Epigenetic Age
DNA methylation clock-based biological age.
Metabolic
Metabolic Age
Advanced insulin, lipid, and glucose composite.
Cardio
Cardiovascular Age
Vascular and cardiac biomarker aging score.
AI
AI Longevity Coach
Personalised guidance from your lab trends and goals.
Privacy & safety
Your health data is yours.
End-to-end security
All data is stored with role-based access rules. Providers only see their own patients. Your data is never sold or shared with advertisers.
HIPAA-ready design
MELLOW is designed with HIPAA compliance principles in mind — audit logging, access controls, and data minimisation. Always consult your compliance officer for your specific obligations.
How the AI works
Biological age is calculated using the peer-reviewed Levine Phenotypic Age algorithm, which uses 9 standard blood biomarkers. No black boxes — the calculation is published science.
Not emergency care
MELLOW is a wellness and preventive health platform. It is not a substitute for emergency medical care. If you have an urgent health concern, contact your doctor or emergency services immediately.
About MELLOW
Built on validated biomarker science.
MELLOW uses the Levine Phenotypic Age algorithm — a peer-reviewed measure of biological ageing derived from 9 standard blood biomarkers. We give patients and providers a shared, objective view of how fast someone is ageing, and a roadmap to slow it down.
MELLOW is not a diagnostic tool and does not provide medical diagnoses. All clinical decisions remain with the treating provider.
