A recent study in Science challenges previous research claiming taurine's decline is linked to aging. It found that taurine levels in healthy mammals, including humans, do not necessarily decline with age. This study, cited by experts like David Sinclair of Harvard, suggests that low taurine levels might not be a reliable aging biomarker, contrasting with earlier findings. One of the study's authors suggested that taurine supplementation is unnecessary for those with a balanced diet, with further clinical trials underway to investigate taurine's benefits.
Writing at Nature, Humberto Basilio examined the study with an eye towards seeing where it fits with the ongoing discussion over taurine's health benefits.
Rafael de Cabo told Nature that 'there's no need for taurine supplementation as long as you have a healthy diet.'
The scientists found that, as they phrased it, 'circulating taurine does not decline with age' in healthy mammals in the species the study encompassed.
