What are organ systems?
The body is a collection of systems that work together but age at different rates. Your immune system defends you and repairs damage. Your cardiovascular system moves blood, oxygen and nutrients. Your metabolism turns food into energy and keeps blood sugar and fats in balance. Your skin protects you from the outside world. Each of these systems responds to daily life in its own way, so one may look younger than your calendar age while another looks older.
How your genes play a role
Epigenetic science makes it possible to look at these systems individually. Researchers have identified groups of DNA methylation sites that track closely with how specific systems age. By reading these patterns, a report can estimate a separate biological age for immune, cardiovascular, metabolic and skin aging. These are estimates drawn from methylation, not organ scans, and they are most useful as a guide.
A single biological age is useful, but it can hide detail. If one system appears to be aging faster than the others, that is a helpful signal of where to direct your attention and which questions to bring to your clinician. If a system looks younger than expected, that is worth knowing too. Seeing the full picture helps you set priorities calmly, rather than trying to change everything at once.
What your report shows
Your Organ Systems results are explained in plain language in your private EvoDNA account, alongside the other areas in your kit.
- Immune agingAn estimate of how your immune system may be aging, based on methylation patterns.
- Cardiovascular agingA view of how the systems tied to your heart and blood vessels may be aging.
- Metabolic agingAn estimate of how the systems that manage energy and blood sugar may be aging.
- Skin agingA look at how your skin may be aging at the cellular level, beyond what the mirror shows.
Each result comes with a plain-language explanation and practical points to discuss with your clinician.
Illustration only. Your report reflects your own genetic results.
Putting results to use
Many people use their results as a starting point for conversations with their clinician about:
Regular aerobic activity is often discussed as support for the cardiovascular system.
Steady, fiber-rich meals are commonly linked with healthy metabolism.
Shade, clothing and sunscreen are widely recommended to protect skin over time.
Good sleep and social connection are often linked with a well-supported immune system.
Questions
Why would my systems have different ages?
Each system is exposed to different stresses and demands over a lifetime. Genetics, environment and habits can affect them unevenly, so their epigenetic patterns can differ.
Is this a medical assessment of my organs?
No. These are epigenetic estimates of aging, not diagnostic tests or imaging. They are best used as a starting point for conversations with your clinician.
Which system should I focus on first?
Many people start with the system that appears furthest from their calendar age. Your clinician can help you decide what makes sense alongside your full health history.
