    Epigenetic Age Reversal

    Younger biological age markers through epigenetic modification.

    TL;DR

    Epigenetic clocks are research tools, not verified targets for intervention. Nothing sold as an anti-ageing supplement has been shown to slow real ageing; the levers with actual outcome data are exercise, sleep, not smoking, and body composition.

    Why It Matters

    DNA methylation clocks such as GrimAge and PhenoAge correlate with mortality and disease risk at population level, but individual test-retest variability is large enough to swamp most short-term changes. Treat a single result cautiously.

    How to Measure

    Biomarkers

    DNA methylation age (GrimAge, PhenoAge)
    hs-CRP
    HbA1c
    VO2 max
    Grip strength

    Optimization Protocol

    Focus on interventions with mortality data: aerobic and resistance training, seven to nine hours of sleep, no smoking, moderate alcohol at most, and a healthy body composition. If you test a methylation clock, retest with the same provider at least 12 months apart and ignore small swings. Treat NMN and resveratrol as experimental.

    Supporting Supplements

    Resveratrol

    Compound
    Not supported
    Moderate Evidence
    Effectiveness 1/5

    The evidence has moved against it. Spend elsewhere.

    NMN

    Compound
    Insufficient evidence
    Limited
    Effectiveness 2/5

    Mechanistically interesting, clinically unproven. Buying it is buying a hypothesis.

    Frequently Asked Questions

    Can biological age actually be reversed?
    Epigenetic clocks can shift with intervention in small studies, but whether that reflects genuine rejuvenation or measurement variability is unsettled. Treat reversal claims cautiously.
    Are consumer epigenetic age tests reliable?
    Test-retest variability can be substantial - several years on repeat sampling in some evaluations - so a single result is a weak basis for decisions.
    What has been studied?
    One small uncontrolled trial combining growth hormone, DHEA and metformin reported a reduction in epigenetic age, and a diet-and-lifestyle trial reported a smaller shift. Both are preliminary.
    Do NAD precursors or resveratrol reverse ageing markers?
    Neither has shown convincing epigenetic age reduction in humans. Mechanistic plausibility from animal work has not translated into reliable human outcomes.
    Which interventions have the best supporting data?
    Not smoking, regular exercise, adequate sleep, a predominantly whole-food diet and maintaining muscle mass all associate with slower epigenetic ageing in observational work.
    Is a lower epigenetic age meaningful?
    It correlates with mortality risk at population level, but it has not been established as a target that changes individual outcomes when deliberately shifted.
