Metabolomic age acceleration (mAA) and DNA methylation age acceleration (DNAmAA) capture distinct aspects of the aging process, as they are uncorrelated with each other despite both being associated with different risk factors.
Relying on just one 'biological age' test might give you an incomplete picture. This research suggests that metabolic health (blood/urine markers) and genetic expression (DNA methylation) track aging differently. To truly understand your aging trajectory, you might need to look at multiple health indicators rather than relying on a single metric.
GoodQualifiesHIGH confidence
DNA methylation age acceleration measures were uncorrelated with mAA... metabolomic age is complementary to established epigenetic clocks.
Why this rating
Large sample, multi-platform validation, and direct comparison of two major aging clocks.
