Understanding Epigenetics and Longevity

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

What Are Epigenetics?

Epigenetics refers to modifications to DNA that affect gene expression without altering the underlying genetic sequence. These modifications, such as DNA methylation, act as switches that can turn genes on or off, influencing cellular function and overall health.

Unlike your genetic code, which remains relatively static throughout life, your epigenetic patterns are dynamic and responsive to environment, lifestyle, nutrition, and ageing.

The Epigenome's Role in Biological Systems

The epigenome plays a crucial role in numerous physiological processes:

• Cellular ageing: Regulating cellular senescence and repair mechanisms
• Energy production: Influencing mitochondrial function and efficiency
• Stress response: Modulating how your body adapts to physical and psychological stressors
• Immune regulation: Calibrating inflammatory responses and resilience
• Neurological function: Affecting cognitive performance and brain health
• Hormonal balance: Influencing production and sensitivity to various hormones
• Exercise adaptation: Determining how your tissues respond to different training stimuli
• Detoxification capacity: Controlling how efficiently your body processes environmental compounds

Epigenetics and Longevity Research

Research increasingly demonstrates that epigenetic patterns are closely linked to biological ageing and longevity, with specific methylation signatures associated with health outcomes and lifespan. By analysing these patterns, we can gain unprecedented insights into your biological age and health trajectory.

Why This Matters for Your Health

Understanding your epigenetic patterns provides:

• Deeper insights: Reveals epigenetic regulation patterns that influence health and longevity at a level unavailable in standard testing
• Personalised precision: Your epigenetic patterns are as unique as your fingerprint—helping explain why generic health approaches may yield different results for you
• Actionable specificity: By identifying specific methylation patterns, we can pinpoint precise lifestyle, nutritional, and environmental optimisations most likely to support your longevity
• Longitudinal tracking: Establishing your baseline epigenetic profile allows you to monitor changes over time as you implement lifestyle modifications—creating a feedback loop for continuous optimisation

Comprehensive Analysis: 66 Biological Markers

While standard epigenetic tests may focus on a limited set of markers, our analysis examines a diverse array of methylation sites associated with key aspects of health and longevity across 66 distinct biological modules.

SLEEP ARCHITECTURE Sleep Architecture & Recovery +

The quality of your sleep profoundly affects virtually every aspect of your health. Our analysis reveals how your epigenetic patterns influence sleep timing, quality, and recovery mechanisms.

• Ideal Sleep Window: Methylation patterns in your clock genes (CLOCK, PER1-3, CRY1-2) reveal your chronotype—whether you're naturally a morning lark or night owl. These epigenetic signatures help explain individual variations in optimal sleep timing beyond simple preferences.

• Sleep Quality Markers: Biological patterns affecting sleep architecture—including slow-wave sleep generation, REM cycling, and micro-awakening propensity. These markers help explain why some individuals feel refreshed after 6 hours of sleep while others need 9 hours.
• Stress-Induced Sleeplessness: Methylation patterns at stress response elements that influence how your HPA axis and GABA system affect sleep during periods of elevated stress.

ENERGY & CELLULAR VITALITY Energy & Cellular Vitality +

The foundation of your daily energy and resilience begins at the cellular level. These markers reveal how efficiently your cells produce and manage energy.

• Mitochondrial Function: Epigenetic regulation of mitochondrial biogenesis and efficiency—determining how effectively your cellular powerhouses convert nutrients into ATP energy. These patterns directly impact your baseline energy capacity and recovery potential.
• Chronic Fatigue Propensity: Methylation sites associated with central and peripheral fatigue mechanisms—potentially explaining why some individuals experience persistent fatigue despite adequate rest and nutrition.
• Cellular Energy Pathways: Epigenetic patterns influencing metabolic flexibility—your cells' ability to switch between different fuel sources (carbohydrates, fats, ketones) for optimal energy production.
• Muscle Recovery Speed: Biological patterns affecting post-exertion protein synthesis, inflammation resolution, and glycogen replenishment—critical for understanding your natural recovery timeline after physical activity.
• Oxidative Stress Defence: Methylation sites regulating SOD2, catalase, NRF2, and other protective enzyme systems that shield your mitochondria from damage.

Your brain's function and long-term resilience are significantly influenced by epigenetic patterns. These markers reveal factors affecting your cognitive performance and neurological health trajectory.

• General Cognition Factors: Methylation patterns affecting attention regulation, memory formation, and cognitive processing speed—providing insights into your natural cognitive strengths and optimisation opportunities.
• Hippocampal Volume Propensity: Epigenetic sites associated with neurotrophin production, particularly BDNF—the growth factor most closely linked to memory formation, hippocampal health, and cognitive resilience.
• Neurodegenerative Resilience: Biological patterns linked to specific cognitive risks including Alzheimer's disease markers affecting amyloid processing and tau metabolism, Parkinson's-related dopaminergic pathway regulation, vascular dementia risk factors, Lewy body propensity, and frontotemporal lobe resilience factors.
• TBI/Concussion Response: Methylation patterns that influence neuroinflammatory resolution, blood-brain barrier integrity, and neuronal repair mechanisms—critical factors in how effectively your brain recovers from trauma.

HORMONAL BALANCE Hormonal Balance & Regulation +

Your endocrine system coordinates virtually every aspect of your physiology. These markers reveal how your hormonal systems function and communicate.

• Thyroid Function: Epigenetic patterns affecting TSH sensitivity, T4 to T3 conversion efficiency, and autoimmune thyroid risk—explaining variations in metabolic rate, energy regulation, and temperature control.
• Stress Hormone Patterns: Methylation sites influencing cortisol production, metabolism, and receptor sensitivity—along with DHEA-S regulation, which provides balance to cortisol effects. These patterns help explain individual variations in stress resilience and recovery.
• Sex Hormone Regulation: Biological markers affecting testosterone production, sensitivity, and metabolism; oestrogen receptor response and metabolite elimination; DHT conversion pathways and prostate health; and SHBG production affecting hormone bioavailability.
• Metabolic Hormones: Epigenetic patterns influencing insulin sensitivity, adiponectin production, and leptin signalling—critical regulators of energy storage, usage, and satiety mechanisms.

How your body processes and utilises nutrients is fundamental to cellular function. These markers reveal your metabolic tendencies and nutritional needs.

• Carbohydrate Metabolism: Methylation patterns affecting insulin signalling, glucose transport, and glycogen storage—revealing your natural carbohydrate tolerance and potential weight loss response to different dietary approaches.
