1000–3000 mgWith meals or pre-workout

Taurine is a conditionally essential amino acid — the most abundant free amino acid in the heart, brain, and retina. Despite its association with energy drinks, taurine is actually calming and supports cardiovascular function. A landmark 2023 paper in Science demonstrated that taurine supplementation extended healthy lifespan in mice, worms, and monkeys, generating significant scientific interest in its anti-aging potential.

TL;DR: Conditionally essential amino acid. Landmark 2023 Science paper showed it extends healthy lifespan in multiple species.
