Introduction
Intensive training—especially eccentric movements, where muscles lengthen under tension—often causes microscopic muscle damage. This leads to inflammatory responses and an increase in reactive oxygen species (ROS), which can temporarily reduce muscle strength and performance. Taurine, a sulfur-containing amino acid found in high concentrations in skeletal muscles, is known for its antioxidant and cell-protective effects. A study published in Antioxidants specifically investigated whether taurine can aid recovery after eccentric exercise-induced muscle damage in men (Antioxidants-06-00079).
What is Taurine?
Taurine is an amino acid naturally present in skeletal muscles, the heart, and the nervous system. It plays a key role in:
- Neutralizing free radicals (ROS),
- Protecting cell membranes,
- Regulating calcium in muscle cells.
Unlike many traditional antioxidants, taurine appears to support recovery without suppressing the natural adaptive responses to training—such as muscle growth and adaptation to load.
Key Findings from Scientific Research
In the study by McLeay et al. (2017), ten recreationally fit men participated in a crossover experiment. They performed 60 maximal eccentric contractions of the biceps, followed by three days of supplementation with taurine (0.1 g·kg⁻¹ body weight twice daily) or a placebo. The results showed:
- Clear strength loss: Within 24 hours after training, muscle strength significantly decreased in all participants—a sign of muscle damage.
- Recovery benefits with taurine: Only eccentric peak strength recovered faster in the taurine group, showing a clear advantage after 48 hours compared to placebo.
- No difference in CK levels: The marker creatine kinase (CK), often used to indicate muscle damage, showed no significant differences between taurine and placebo.
Conclusion: Taurine may primarily help accelerate recovery of eccentric muscle strength, which is relevant for heavy resistance or interval training.
How Taurine Supports Recovery
Taurine’s benefits are mainly due to its antioxidant and cell-protective properties:
- Reduction of oxidative stress: Taurine neutralizes free radicals released during intense exercise, limiting secondary muscle damage.
- Faster strength recovery: Research suggests taurine can accelerate the return of eccentric muscle strength.
- Cell-protective role: Taurine supports muscle cell integrity and helps limit inflammation-induced damage without blocking adaptive processes.
How to Use Taurine for Optimal Results
Although further research is needed, existing studies provide some practical guidelines:
- Dosage: ~0.1 g·kg⁻¹ body weight per day (roughly 6–10 g for most adults), split into two intakes.
- Timing: Administered before and after exercise, this regimen effectively reduces blood lactate levels, indicating improved aerobic performance.
- Combination: Taurine can be safely combined with other performance supplements such as creatine and beta-alanine.
