Endurance

Does it work?

-A little. Taurine gives a small, real bump to endurance — meta-analyses put it at a modest effect (Hedges' g ≈ 0.25–0.40), roughly on par with a slightly better time-to-exhaustion. It's safe and cheap, but it's a minor edge, not a game-changer. Worth a try for endurance work; not worth high hopes.

How much · when

-Take 1-6 g as a single dose. There's no clear dose-response in that range, so ~2-3 g is a sensible, cheap starting point.
-Time it 1-2 hours before endurance work — pre-exercise timing looks most favorable in the data.
-Daily loading isn't needed: a single acute dose works about as well as weeks of supplementation. Take it on session days.
-Pure taurine powder is far cheaper than energy drinks, where the taurine dose is usually too low to matter anyway.

The catch

-The effect is small and inconsistent — it shows up for aerobic endurance and time-to-exhaustion, but evidence for anaerobic and muscular-endurance tasks is shaky.
-Trial quality is mixed and effects shrink in better-blinded studies, so the true benefit may be smaller than the headline numbers.
-It won't outperform getting your training, sleep, and carbs right — taurine is a marginal add-on, not a foundation.

Safety

-Very well tolerated; doses up to ~3 g/day are considered safe with no notable side effects in healthy adults.
-Skip the energy-drink route if you're sensitive to caffeine — those products bundle taurine with stimulants, not the other way around.
