The Antagonistic Effects of Caffeine and Taurine

Brian Turner

Posted on January 01 2017

In 2013, worldwide sales of energy drinks exceeded $50 billion. The principal ingredients of these beverages are typically caffeine, taurine and usually high fructose corn syrup. A study from Colombia found that identically tasting beverages containing either caffeine (80 milligrams), taurine (1,000 milligrams), a combination of caffeine and taurine, or a commercial energy drink (Red Bull) had no effect on cardiorespiratory fitness, endurance, strength, power or cognitive ability. Combining caffeine with taurine has antagonistic effects. For best performance results, skip the taurine in your energy or pre-workout drink.
