metabolic vulnerability index (MVX) predicts 5-year all-cause mortality (out-predicting chronological age)
In plain terms: Can a blood-metabolite 'vulnerability' score predict death better than your age?
In its derivation cohort the NMR-based MVX score predicted near-term mortality strongly and added prediction beyond chronological age, with several independent cohorts now replicating it.

| Source | Grade | Stance | Quality | Finding |
|---|---|---|---|---|
| Li 2025 · Redox Biol | observational | supports | high | In 274,092 UK Biobank participants the metabolic vulnerability index (MVX) showed a graded association with all-cause mortality (top-quartile HR 1.21). |
| Mateus 2025 · J Healthc Inform Res | observational | supports | moderate | Federated analysis of three cohorts found MetaboAge and MRI-based BrainAge acted synergistically to predict time to all-cause mortality. |
| Gu 2026 · Nutr Metab Cardiovasc Dis | observational | supports | moderate | An externally validated plasma metabolomic signature predicted 3-year all-cause mortality in older CAD patients with incremental value over clinical risk factors. |
| van Holstein 2024 · Geroscience | observational | mixed | moderate | In 192 older cancer patients MetaboHealth was associated with 1-year mortality (HR 2.32/SD) but added only marginally (AUC 0.76 to 0.80) beyond clinical predictors. |
| Lau 2024 · Aging Cell | observational | mixed | high | Independent UK/Finnish multicohort (~133k): NMR metabolomic age/mortality models only moderately track chronological age but DO add mortality prediction beyond age — supports added value, tempers 'out-predicts age' framing. |
| Otvos 2023 · Lancet Healthy Longev | observational | supports | moderate | MVX origin paper (Otvos/Shalaurova/McGarrah/Kraus; NO Norwitz/Feldman/Soto-Mota=independent of LMHR net): NMR metabolic+inflammation markers predict mortality strongly. NMR-platform-dev COI noted. |
| Horne 2009 · Am J Med | observational | supports | moderate | A risk score from routine complete-blood-count and metabolic-panel components strongly predicted all-cause mortality, showing multi-analyte scores add prognostic information. |
| Conners 2024 · JACC Heart Fail | observational | supports | moderate | Independent group: MVX predicted mortality in heart-failure patients, adding prognostic value beyond conventional markers — external replication of MVX mortality signal. |
| Fischer 2014 · PLoS Med | observational | supports | high | NMR biomarker profiling in 17,345 persons identified a 4-biomarker score predicting short-term all-cause mortality, adding to conventional risk factors. |
| Kuiper 2023 · J Gerontol A Biol Sci Med Sci | observational | supports | high | MetaboHealth (mortality-trained metabolomic score) predicted mortality and frailty independent of epigenetic clocks, outperforming age-trained markers. |
| Wang 2024 · EBioMedicine | observational | supports | moderate | A lipidomic metabolic age score captured cardiometabolic risk and associated with all-cause mortality independent of chronological age across validation cohorts. |
Disagree, or know a study we missed?
We grade by evidence, not opinions. The way to weigh in is to point us to a study we haven't cited (check the evidence table above first), or to flag a problem with one we have. Every submission is reviewed; if it holds up, the grade updates and shows in Science Changes Its Mind.
Opens a short form. You'll sign in with Google so submissions are tied to a real account — we don't display your identity, and we only accept a link we can verify (PubMed, DOI, ClinicalTrials.gov).
Educational only, not medical advice. Grades and scores reflect published evidence weighted by study design and quality; see the methodology.
