Taurine for Enhanced Athletic Performance
Taurine produces small ergogenic effects on endurance performance, with acute doses of 1-6 g showing the most consistent signal.
Overview
Verdict
How It Works
Dosing & Protocol
Typical dose
- Recommended dose
- 1-3 g taurine taken 1-3 hours before exercise, or 1-3 g/day chronically; trials span 1-6 g
- Expected timeframe
- 1-8 weeks
Protocol
- form
- Taurine powder or capsules; take it separately from energy drinks so the effect is not confounded by caffeine
- duration
- Acute effects are testable within a session; chronic protocols run 1-8 weeks
- co factor
- Take with or without food, 1-3 hours before exercise. Evidence is mixed. A 2018 meta-analysis by Waldron and colleagues found a small but significant improvement in endurance performance with acute taurine ingestion of 1-6 g, and separate work suggests reduced muscle damage markers and soreness after eccentric exercise. Against this, effects on strength, power and sprint performance are inconsistent or absent, doses and timing vary widely across trials, and many studies are small crossover designs in trained young men. Proposed mechanisms include improved calcium handling in muscle, membrane stabilisation and reduced oxidative damage.
- titration
- Up to 3 g/day, either as a single pre-exercise dose or divided; 6 g/day has been used short term in trials
- starting dose
- 1 g taken 60-120 minutes before training

Safety
Caveats
The effect size is small and clearest for endurance rather than strength or power, and the supplements with substantially stronger performance evidence are creatine monohydrate at 3-5 g/day, caffeine at 3-6 mg/kg, and beta-alanine at 3-6 g/day for high-intensity efforts of 1-4 minutes. Training programming, sleep, and adequate energy and protein intake matter far more than any of them. Safety of taurine: it is among the best tolerated supplements, with no serious adverse effects at doses up to 3 g/day sustained and 6 g/day short term, and EFSA has considered 6 g/day tolerable. Diarrhoea and nausea occur at high doses. It has modest blood-pressure-lowering effects, relevant if you take antihypertensives, and may enhance lithium effects. Caution applies in significant kidney impairment. Safety in pregnancy and breastfeeding beyond dietary amounts is not established. Do not take it via energy drinks, where the caffeine and sugar drive the effects and the cardiovascular load is different. Competitive athletes should check third-party certification such as Informed Sport for contamination.
