Taurine for longevity

Taurine supplementation. Aging itself. Reviewed Jul 2026.

Extended healthy lifespan by about 10 to 12% in mice, but there is no human outcome data and later analyses question whether taurine really declines with age.

Stage
Preclinical, human trials under way
Rung: Experimental. Animal, lab or theoretical. Years away, if ever.
Evidence grade
D
animal data only
Animal or lab only, single pilot, or case reports. How grades work.

What it is

Restoring levels of the amino acid taurine, which decline sharply with age across species.

The evidence

Science (2023): taurine supplementation extended healthy lifespan ~10–12% in mice and improved markers in monkeys. Human RCTs are ongoing; causal benefit in people is not yet proven and some later analyses question the age-decline pattern.

What you can do today

Not available for this use, and years away if it arrives at all. Anything sold today with this claim is not backed by human evidence for it.
