A model built from methylation patterns
The result is an estimate produced by a selected model, not a direct measure of one universal ageing state.
Legacy testing guide
One reading. Used carefully.
Epigenetic testing examines DNA methylation patterns and compares them with patterns seen across age groups. In Lyxaa's Legacy tier, it is a one-time first-year reading, not a score that is repeatedly chased.

In short
Legacy includes one epigenetic test in the first membership year. It is not repeated on renewal, is not used as a diagnosis and is not presented as a trackable measure of change.

Guide overview
Understand what the estimate is before deciding how much weight to give it.
Epigenetic clocks are statistical models. They are scientifically interesting, but different methods can produce different estimates and their personal clinical meaning remains limited.One first-year Legacy reading
Lyxaa does not repeat it on renewal or use it as a score to chase across the membership.
Not diagnosis or proof of reversal
Standard clinical assessment and the programme's scheduled panels remain more immediate decision inputs.
What epigenetic testing measures
The test reads selected DNA methylation patterns. Statistical models compare those patterns with reference data to produce an estimate.
The result is different from a genetic diagnosis. It does not rewrite your DNA, predict one exact future or replace standard clinical investigation.
Why Lyxaa treats it as one reading
Different epigenetic clocks use different methods and can produce different estimates. Personal interpretation also has limits.
For that reason, the Legacy inclusion is deliberately defined as one first-year reading. It is not sold as a number to improve and retest every year.
How it differs from microbiome testing
| Testing layer | When it happens | How it is used |
|---|---|---|
| Gut microbiome | At the start of each membership year | A year-over-year comparison becomes possible from year two |
| Epigenetic | Once, in the first Legacy year | A single contextual reading, not a repeated trend |
What it does not prove
- It does not diagnose disease.
- It does not prove that ageing has been reversed.
- It does not replace the full panels or priority-marker checks.
- It does not determine the programme by itself.
Where the practical work remains
The programme still rests on precision nutrition and functional training, supported by the scheduled clinical reviews. The epigenetic result is one additional layer at Legacy.
Your full panels, priority markers, symptoms, history and daily context remain more immediate inputs to decisions made across the year.
Why two reports may not match
Epigenetic clocks can use different methylation sites, reference groups, algorithms and sample methods. Two services may therefore produce different estimates without either number acting as one universal truth.
That variation is one reason to avoid comparing unrelated reports or treating a small numerical difference as a confirmed change in health.
How to read the result responsibly
- Ask which model and sample method were used.
- Separate an estimate from a diagnosis or prognosis.
- Do not change treatment because of the result alone.
- Keep the programme focus on scheduled clinical review, nutrition and functional training.
Common questions
Clear answers before you choose a next step.
Is epigenetic age the same as my actual age?
No. Chronological age is time since birth. An epigenetic estimate is produced by a statistical model using selected DNA methylation patterns and reference data.
Can the test prove that ageing has reversed?
No. A single estimate cannot prove that ageing has reversed, diagnose disease or predict one exact future.
Why is it not repeated every year?
Different clocks and technical methods have interpretation limits. Lyxaa therefore includes one first-year reading at Legacy rather than selling repeated testing as a validated personal trend.
