Biological aging
Metabolomic aging clock
An aging estimate derived from metabolite profiles.
What it measures
A multivariate metabolite signature trained against age or health outcomes.
Why it matters
May capture dynamic metabolic state and aging-related risk.
How to interpret it
Interpret within the exact analytical platform and model.
Important limitations
Sensitive to diet, fasting, medications and platform differences; clinical utility is not established.
Evidence status
Research-stage biomarker
Promising research class requiring standardized external and intervention validation.
Research & guidance
Original papers, validation studies, reviews and clinical guidance connected to this measurement.
