Why epigenetic testing for biological age analysis?
For centuries, we've measured ageing in terms of calendar years - your chronological age. However, science now reveals that this only tells part of the story. Your biological age - determined by analysing specific epigenetic markers - shows how quickly your cells are actually ageing, which can be dramatically different from the number of candles on your next birthday cake.
DNA methylation patterns serve as the most scientifically validated biomarkers of ageing, revealing how your lifestyle and the environment have affected your cells over time. Understanding your biological age enables targeted interventions that could potentially slow aspects of cellular ageing.
StrideBioage measures what truly matters: not how long you've been alive, but how well your body is ageing.
Why StrideBioage?
StrideBioage brings professional blood testing to the comfort of your home. Our qualified phlebotomists come to your chosen location, ensuring a convenient, stress-free blood draw experience with expert collection.
Using gold-standard epigenetic analysis, we translate your blood data into clear, actionable Biological Age and Stress Impact reports. Rather than complex scientific information, you'll receive practical recommendations tailored to your unique methylation patterns - revealing how factors like diet, tobacco use, alcohol consumption, and physical activity are influencing your ageing process.
Includes a complimentary 1:1 consultation with our dietetics and lifestyle experts to help you understand your results and get guidance on implementing the recommended age-slowing interventions.
For Premium customers, our Stress Impact profile even identifies which physiological systems are most impacted by your stress patterns. By testing bi-annually, you can track your progress and refine your approach to optimise your health span and potentially add quality years to your life.

Biological Age Reports
The StrideBioage Biological Age assessment examines epigenetic markers that influence your body's true biological age vs chronological age.
Biological Age score
Your comprehensive biological age calculation is based on advanced epigenetic analysis. This score reveals whether your body is ageing faster or slower than your calendar age suggests.
Youth capital
Discover your "youth capital" - the difference between your biological age and chronological age. This critical measurement reveals whether you're building a longevity surplus or deficit, and how much biological youth you've gained or lost over time.
Population comparison
See exactly where you stand compared to others in your age group. Your percentile ranking shows what percentage of the population has better or worse ageing markers than you, providing valuable context for your results.
Lifestyle sensitivity
For each lifestyle factor (diet, exercise, alcohol, tobacco), we measure your personal "sensitivity" - how strongly your body responds to specific behaviours. If you report high exercise levels but show minimal epigenetic impact, this indicates low exercise sensitivity - meaning you may need different types or intensities of activity to see biological benefits.
Lifestyle Impact Analysis
Discover how specific habits are influencing your ageing process, including:
Diet and nutrition quality
See how your nutrition choices are affecting your biological age at the cellular level. Your report will identify dietary patterns through epigenetic markers in your DNA that reflect your actual consumption, e.g. of fruits and vegetables, vs these biological markers with public health recommendations.
Physical activity
Understand how your exercise patterns are impacting your ageing trajectory. Your report quantifies the epigenetic signatures of regular activity, showing whether your body is receiving sufficient movement to slow ageing.
Alcohol consumption
Measure the precise effect that alcohol intake is having on your epigenetic ageing markers. Beyond just reporting your consumption, we identify how your body personally metabolises alcohol and whether your current intake is accelerating your biological ageing process.
Tobacco exposure
Quantify how smoking or environmental tobacco exposure is influencing your biological age. Even past smoking history leaves detectable epigenetic markers that our analysis can identify, showing whether previous exposure continues to affect your ageing process.
Stress Impact Reports
Exposure to chronic stress can have a huge impact on our health and wellbeing. This impact is known as allostatic load, and our body's capacity to adapt to this load can be severely tested over time. Different physiological and psychological stressors contribute to allostatic load, which can potentially escalate the onset of disease and impact longevity.
Your StrideBioage Stress Impact profile offers a deep dive into how stress affects various bodily systems differently from person to person. Unlike standard stress tests that only measure cortisol levels, our comprehensive analysis reveals how stress impacts your body at the cellular level. We examine which specific physiological systems are contributing to your allostatic load, serving as a measure of your ability to maintain balance and equilibrium when confronted with stress factors.
System-Specific Stress Impacts
Metabolic system
Discover how stress is affecting your metabolic health, including glucose regulation, insulin sensitivity, and energy production. Your report will identify whether stress is disrupting your metabolic pathways and potentially contributing to body weight and blood sugar level management issues.
Immune function
Understand how stress is influencing your immune system's ability to protect you from illness. We measure stress markers that indicate whether your immune response is being over-stimulated or weakened by your stress levels.
Cardiovascular health
See how stress is impacting your heart and vascular system. Your report will show whether stress is contributing to inflammation and other processes that affect cardiovascular health and resilience.
Neuroendocrine balance
Learn how stress is affecting your hormonal regulation and nervous system function. Unlock insights into whether stress is disrupting your body's natural hormonal rhythms and neurotransmitter balance.
Personalised Interventions with Expert Support
Your StrideBioage reports translate complex biological data into clear, practical actions you can take to potentially slow your ageing process and optimise your health. Rather than generic health advice, you'll receive recommendations specifically matched to your unique epigenetic profile, designed to work with your biology, not against it.
Our personalised guidance spans key lifestyle domains including nutrition, physical activity, sleep, stress management, and environmental factors. Each recommendation is evidence-based and tailored to your specific biological needs. To help you fully understand and implement these insights, enjoy a complimentary 1:1 consultation with our dietetics and lifestyle experts.
StrideBioage Premium customers receive additional stress-focused interventions based on their Stress Impact profile results.

For the curious.
What is StrideBioage?
StrideBioage is an advanced epigenetic testing service in the UK that analyses your biological age through DNA methylation markers. Unlike traditional age measurements, it provides a comprehensive snapshot of how well your body is ageing by examining specific biomarkers that reveal your true biological age versus your chronological age.
What does the StrideBioage test measure?
StrideBioage provides a comprehensive health assessment that goes far beyond traditional age measurements. Our test evaluates multiple critical aspects of your health, beginning with a detailed Biological Age Score that reveals how well your body is truly ageing. We calculate your Youth Capital, which highlights the difference between your biological and chronological age, giving you insights into your cellular health. Through population comparison, you'll understand how your health markers compare to others in your age group. Our in-depth analysis explores Lifestyle Sensitivity across key areas including diet and nutrition, physical activity, alcohol consumption, and tobacco exposure.
We also provide a comprehensive Stress Impact analysis (available in StrideBioage Premium) that examines how chronic stress affects your health at a cellular level. This includes insights into metabolic function, immune system performance, cardiovascular health, and neuroendocrine balance. By measuring how stress impacts these critical physiological systems, we offer a unique, holistic view of your overall wellbeing and longevity.
What Biological Age packages are available?
We offer two report options:
StrideBioage: Core biological age assessment with lifestyle optimisation recommendations
