Metabolomics as proposed lens on aging clocks
The review starts from a stated limitation: current epigenetic clocks are described as limited in resolving dynamic metabolic fluctuations and tissue-specific aging trajectories. Metabolomics is presented as a pivotal solution because it represents the endpoint cascade of biological events shaped by multifactorial interactions and captures real-time physiological status. The authors frame biological age as quantifying functional decline beyond chronological aging. These are framing claims of a review, not results of a new measurement study.

Proposed workflow and three-phase causal strategy
The review proposes an executable research workflow with four steps: data preprocessing, feature selection, model construction and model application. It also designs a three-phase causal strategy structured as global screening, local verification and dynamic validation. The stated aim is to enhance predictive accuracy of aging clocks while strengthening biological plausibility and causal inference potential of metabolite-derived aging biomarkers. These are proposed frameworks, not validated clocks or finished products.

Translational prospects described, not demonstrated
The review evaluates translational prospects and applied value of metabolomic aging clocks and says it provides actionable guidance for extending human healthspan and advancing prevention and treatment strategies for aging-related pathologies. The abstract reports no study design, sample, follow-up or measured outcomes, so these translational statements remain proposals and expectations rather than demonstrated effects.
