Reading Epigenetic Age Clocks with Appropriate Skepticism
Biological age testing is popular; interpretation lags behind adoption.

Epigenetic clocks have moved from research settings into consumer products. Their interpretation, however, remains an unsettled science.
Key findings
- Effect sizes vary substantially across studies.
- Applicability to healthy adults remains contingent on further evidence.
- Careful monitoring is warranted when interventions are used off-label.
Clinical context
Recommendations should always be considered within the individual patient's clinical picture.
Limitations
Publication bias, heterogeneous protocols, and short follow-up limit strong conclusions.

A helpful synthesis. The point about study heterogeneity is well-taken; I would add that endpoint selection remains a common weakness in this literature.

Agree on the caution around off-label use in otherwise healthy adults.
