Taurine

Conditionally essential amino acid with promising animal data on lifespan extension. Human data is emerging.

Also known as: taurine

How it works

Taurine is an amino-acid-like compound involved in cell-membrane stability, calcium regulation, bile acids and mitochondrial function. A widely noted 2023 study showed taurine declines with age and that supplementing it extended lifespan in animals. Whether this translates to humans is open.
