Performance evidence brief
Taurine is a sulfur-containing amino acid found in many energy drinks and pre-workouts. It is commonly promoted for endurance, fatigue resistance, hydration, and high-intensity performance.
Some evidence suggests acute endurance or high-intensity benefit, but the research base is smaller than caffeine or creatine.
Review: human taurine studies use <1-6 g from 10 min to 2 h pre-exercise or 7 days-8 weeks.
Doses in studies vary widely; avoid assuming energy-drink doses are equivalent.
Better treated as a watch-list ingredient than a flagship recommendation.

The score reflects evidence that the supplement does its stated job. Some jobs are direct, such as strength, endurance, or recovery; others are indirect, such as sleep, mood, appetite, or health support. A real effect can still receive a cautious practical rating when dose, safety, product quality, or audience fit remain uncertain.
