Anti-aging supplements become popular based more on hype than hard evidence—but researchers are starting to investigate some of the more promising ones to add some scientific rigor to the claims.
The latest is the amino acid taurine: a familiar ingredient in energy drinks and one that scientists have been studying for decades, albeit for reasons other than aging.

In people, the team also reports that taurine levels decline with age and can be boosted with exercise.
