Taurine is a non-proteinogenic amino acid and a derivative of cysteine which has become a very popular ingredient of many sports and energy drinks over the last few decades. Although it occurs in the human body in high concentrations in the brain, heart and muscles, its exact role still remains partly a mystery to science.
The biological functions of taurine
Scientific studies suggest that taurine could have an effect in the following areas:
Taurine and muscle activity
In the context of sports performance, researchers focus on the effect of taurine on skeletal muscle:
A real benefit from supplementation?
Despite the interesting theoretical mechanisms, the real value of taurine as a food supplement for athletes is still ambiguous:
Conclusion for athletes
Taurine is an important substance for physiological processes in the body, especially for muscle and nerve tissue. However, at present there is not enough robust scientific evidence to confirm that supplementing with it leads to a demonstrable improvement in sports performance or a change in muscle metabolism. From the point of view of sports performance, supplementing with taurine is, according to the available information, without effect.
