US EditionStudy Challenges Taurine as a Biomarker of Aging
- A study published in Science on June 5, 2025, by scientists from the National Institutes of Health investigated taurine levels in humans, monkeys, and mice.
- The study followed up on previous conflicting findings and used longitudinal data to clarify taurine’s role as an aging biomarker amid variable results.
- They observed that taurine levels generally stayed the same or increased with aging, and that differences between individuals, dietary habits, sex, and species played a larger role in taurine variation than aging did.
- Co-Author Rafael de Cabo emphasized that taurine supplements are unnecessary if one maintains a balanced and nutritious diet, noting that the association between taurine levels and health outcomes is inconsistent.
- The findings cast doubt on taurine’s value as a reliable aging biomarker and suggest its supplementation benefits may depend on individual contexts.

How Effective Is Taurine When It Comes to Aging?
In June 2023, the journal Science published a study that explored whether or not taurine had any effect on the effects of aging. “Loss of taurine in humans was associated with aging-related diseases,” editor L. Brian Ray wrote, though there were some big caveats — notably, that its benefits were observed in worms, mice and monkeys. Two years later, however, another study published in the same journal complicates the picture.That study, titled “I…
Results from a longitudinal study published in Science show that taurine is not a reliable biomarker of aging.
The paper, published in Science, discusses the value of amino acid as a biomarker of aging and dismisses recommending it in a general way.
