Taurine — an amino acid found in some foods and also made by the human body — has been shown to slow aging in animals when given as a supplement, raising the idea that it might be a promising anti-aging treatment for people. But now, a new study has raised questions about taurine's relationship to aging.
The study, published Thursday (June 5) in the journal Science, measured taurine in the blood of three groups of people across adulthood, as well as in the blood of adult monkeys and mice. Some previous studies found that circulating taurine declines with age, which could help explain why taurine supplements improve certain signs of aging while extending lifespan — at least in lab animals.
