Epigenetic testing is a type of analysis that looks at how your lifestyle, environment, and behavior affect your gene expression—without changing your DNA sequence itself.
Unlike genetic tests (which analyze your fixed DNA code), epigenetic tests measure chemical tags on your DNA—especially DNA methylation—that turn genes on or off. These changes can influence things like aging, disease risk, metabolism, and stress response.
Most tests focus on:
Biological age (how “old” your body is at the cellular level)
DNA methylation patterns (chemical markers on genes)
Healthspan markers (related to inflammation, stress, longevity)
Lifestyle impact (how diet, sleep, toxins, etc., are affecting your cells)
Some more advanced tests may also give insight into:
Detox ability
Metabolic efficiency
Hormone regulation
Cognitive aging
Immune system function
Sample Collection – Usually a saliva, blood, or cheek swab.
Lab Analysis – The lab reads epigenetic markers (like methyl groups on DNA).
Reporting – You receive a report with:
Your biological vs. chronological age
Insights into your current health status
Recommendations for lifestyle changes
Some tests also track before-and-after changes, making them popular among:
Biohackers
Longevity enthusiasts
People using the Superhuman Protocol, peptides, or stem cell therapy
TrueDiagnostic – Popular for tracking biological age and interventions
TruAge – Tests multiple biological aging clocks (e.g., Horvath, GrimAge)
EpiAging or Zymo Research – More clinical and research-based
DunedinPACE – Measures the rate at which you’re aging
Epigenetic testing is becoming a core part of personalized health plans because it:
Tells you how well your lifestyle is working at a cellular level
Helps track the effectiveness of interventions (like red light therapy, fasting, supplements, or stem cells)
Identifies early risk signals before disease shows up in labs
