Taurine for Exercise Performance

Research suggests that taurine supplementation may offer modest but meaningful benefits for exercise performance, particularly in endurance contexts, with the most consistent evidence coming from two meta-analyses pooling data from dozens of randomized trials and finding small-to-moderate improvements in aerobic endurance, strength, and agility tasks. Several randomized controlled trials and mechanistic reviews further support a role for taurine in reducing oxidative stress, supporting mitochondrial function, and potentially blunting core temperature rise during exercise in the heat — effects that appear plausible given taurine's known biological roles in antioxidant defense and skeletal muscle physiology. However, the overall picture is mixed in important ways: evidence for benefits during high-intensity anaerobic or sprint efforts is weaker, the 2025 meta-analysis rated the quality of underlying evidence as low to very low due to small sample sizes, methodological variability, and risk of bias, and an ISSN position statement on energy drinks — which frequently contain taurine — concluded that the independent contribution of taurine beyond co-ingested caffeine and carbohydrates remains largely unproven. Studies indicate that the relationship between dose and response is not straightforward, with different trials reporting different optimal amounts, and while animal research and mechanistic reviews provide a plausible biological rationale, translating those findings directly to human performance recommendations requires caution.
