NIH research questions taurine as a universal ageing biomarker
Longitudinal observations found that circulating taurine did not consistently fall with age.
NIH researchers reported that circulating taurine often remained stable or increased with age across studied cohorts and species. Relationships with health outcomes varied.
The finding challenges a universal biomarker claim; it does not by itself settle every possible therapeutic question about taurine. The case shows why longitudinal validation matters when translating promising early findings.
