Taurine
A common energy-drink and pre-workout ingredient — plausible small effects, weak stand-alone evidence.
An amino acid involved in hydration, muscle function and antioxidant defence. Frequently paired with caffeine in pre-workouts.
Some evidence for minor endurance and recovery benefits, but the stand-alone data is limited and inconsistent. It's likely a minor contributor at most, and hard to separate from the caffeine it usually travels with.
- !Don't expect much on its own.
- !Well tolerated in typical doses.
