The Science Behind Your Biological Age

Biological age based on DNA methylation patterns is a more accurate guide of wellness outcomes than chronological age

When we set out to create TruAge, we asked a simple question: "What if we could read the biological story written in your cells?" The result is a technology that reveals aging patterns invisible to standard tests—providing insights that can transform how you approach longevity and wellbeing.
‍
Advanced epigenetic algorithms enable precise quantification of multiple aging dimensions beyond a single biological age number. The pace of aging, not just current biological age, provides critical insights into your aging trajectory. Comprehensive analysis across pace of aging, telomere health, immune function, and mitotic age offers integrated assessment. Your results create a personalised blueprint for targeted longevity interventions across multiple biological dimensions.

Understanding Epigenetic Aging Assessment

How your lifestyle choices influence gene expression without changing DNA—and why this matters for aging.

Reading Your Cellular Software

Your DNA is like your body's hardware—it stays relatively unchanged throughout life. But your epigenetic patterns are the software—constantly updating based on how you live.

By examining these patterns, we can see how your experiences, environment, and choices have influenced your cellular function—revealing not just your current status, but the trajectory of your aging process.

Research in this field continues to explore how methylation patterns relate to biological processes. While chronological age simply counts years lived, methylation patterns may provide additional insights into cellular processes that researchers are studying for their potential relevance to wellbeing.

Key Insight

The epigenome—the complete set of epigenetic modifications in your DNA—plays a crucial role in numerous aging processes.

The Epigenome's Role in Biological Systems

The epigenome plays a crucial role in numerous physiological processes:

  • Pace of Aging Assessment: Examining the rate at which your biology is aging rather than simply the current state
  • Telomere Length Analysis: Evaluating methylation patterns associated with telomere function and cellular replication
  • Immune Epigenetics: Assessing immune system aging and inflammatory patterns at the epigenetic level
  • Mitotic Age Evaluation: Analysing cumulative cellular divisions and their relationship to tissue health and regeneration
  • Multi-Omic Integration: Combining multiple biological systems into a comprehensive aging assessment

Epigenetics and Aging Vitality Research

This multi-dimensional approach provides unprecedented insight into your biological aging at the functional level where it may impact recovery and longevity potential.

Biological Age Clocks

Epigenetic clocks use methylation patterns to predict biological age with remarkable accuracy, often revealing significant differences from chronological age.

Lifestyle Responsiveness

Studies show epigenetic patterns respond rapidly to lifestyle changes, making them powerful tools for monitoring health interventions.

Disease Prediction

Specific methylation signatures can predict susceptibility to age-related diseases years before symptoms appear.

Core Biological Systems Analysis

Our analysis examines foundational methylation sites associated with key aspects of aging.

Pace of Aging+

Pace of aging measures how quickly or slowly your body is biologically aging—essentially the speed at which age-related deterioration is occurring. This dimension focuses not on your current biological age but on your aging trajectory.

Key aspects of this assessment include:

  • Rate of Biological Change: How quickly age-related biological changes are occurring
  • Future Trajectory: Prediction of how aging will progress if current patterns continue
  • Intervention Sensitivity: Potential for modifications to alter aging trajectory
  • Wellbeing Considerations: Potential relevance to general health and vitality

Research shows that pace of aging varies significantly between individuals of the same chronological age, with some people aging as much as 2-3 times faster than others. These differences have profound implications for cognitive function, and longevity potential.

Telomere Health+

Telomere health assessment examines methylation patterns associated with telomere function and cellular replication capacity. While not measuring telomere length directly, this epigenetic approach provides insights into cellular aging processes that influence tissue health and regeneration.

Key components include:

  • Replicative Potential: Indicators of cellular capacity for division and renewal
  • Cellular Senescence Patterns: Methylation signatures associated with cellular aging
  • Tissue Regeneration: Markers related to the body's ability to repair and regenerate tissues
  • Longevity Correlation: Provides insights into the relationship between telomere-associated methylation and various age-related wellness outcomes

This assessment provides insights into cellular aging processes that influence recovery, regeneration, and overall tissue health throughout the body.

Immune Epigenetics+

This dimension examines methylation patterns that researchers have studied in relation to immune function, with particular focus on sites associated with inflammatory processes.

Key components include:

  • DNAm CRP Assessment: Methylation patterns associated with C-reactive protein, a key inflammatory marker
  • DNAm IL-6 Assessment: Epigenetic indicators related to Interleukin-6, a central mediator of inflammatory responses
  • Inflammatory Pattern Analysis: Methylation sites studied in relation to inflammatory processes 
  • Cognitive Relevance: Exploration of potential connections between these patterns and brain health

Research suggests that these methylation patterns may provide more stable information about long-term inflammatory processes than conventional blood tests, which can fluctuate based on recent exposures.

Mitotic Age+

This dimension examines methylation sites that researchers have associated with cellular turnover processes, providing insights into tissue renewal and maintenance.

Key components include:

  • Cumulative Stem Cell Divisions: Assessment of total cellular replication history
  • Tissue-Specific Patterns: Variations in cellular turnover across different biological systems
  • Regenerative Capacity: Indicators of tissue ability to repair and replace cells
  • Health Implications: Relationship between cellular replication history and longevity

This dimension helps explore methylation patterns potentially related to tissue renewal, recovery capacity, and cellular maintenance.

Weight Loss Response+

Weight loss response assessment examines epigenetic patterns associated with metabolic efficiency and responsiveness to caloric restriction.

Key components include:

  • Metabolic Efficiency: Methylation patterns related to energy utilisation and storage
  • Intervention Responsiveness: Epigenetic indicators of how the body responds to dietary changes
  • Individual Variation: Unique patterns that influence weight management strategies
  • Personalised Approach: Tailored recommendations based on epigenetic profile

This assessment helps explain why generic weight management approaches may not be equally effective for all individuals, guiding more personalised and effective strategies.

Alcohol Consumption Impact+

This dimension examines methylation sites that researchers have studied in relation to alcohol metabolism and its potential effects on biological processes.

Key components include:

  • Aging Acceleration: Impact of alcohol consumption on biological aging processes
  • Tissue-Specific Effects: Differential impact on various biological systems
  • Recovery Indicators: Potential for epigenetic patterns to normalise with consumption changes
  • Wellness Implications: Potential relevance to general health approaches

This assessment provides insights into how lifestyle factors may influence methylation patterns, potentially guiding personalized approaches to wellbeing practices.

Fitness Age+

Fitness age assessment examines methylation patterns associated with physical functionality, cardiovascular capacity, and mobility.

Key components include:

  • VO2Max Indicators: Epigenetic markers related to cardiovascular fitness
  • Grip Strength Patterns: Methylation signatures associated with functional strength
  • Lung Function Markers: Indicators of respiratory capacity
  • Gait Speed Predictors: Markers related to mobility and functional movement

This dimension provides insights into physical functionality from an epigenetic perspective, connecting biological aging with real-world physical capacity and performance.
