No Benefit evidence
8 acute, single-dose, double-blind crossover RCTs in 244 healthy adults testing taurine alone. Any positive mood/well-being effects were minor, inconsistent, and typically only appeared when taurine was combined with caffeine, exercise, or sleep deprivation; one trial found lowered vigor after taurine alone. Two of five authors disclosed unrelated funding from a taurine supplement manufacturer (Viridian Nutrition) for other work.
