Taurine supplement makes animals live longer — what it means for people is unclear

Ageing mice, worms and monkeys can live longer or healthier lives when fed large amounts of taurine, a common ingredient in health supplements and energy drinks, a study suggests.

Researchers showed that levels of the naturally occurring amino acid — which has been linked to other aspects of health — decline as the animals age, and that offsetting this loss with a taurine supplement might delay the development of age-related health problems.
