![]() The World Anti-Doping Agency does not include taurine on its list of banned substances, implying that available evidence does not support significant energy-enhancing properties of taurine. The International Society of Sports Nutrition position statement on energy drinks cites the need for additional research on supplements such as taurine to sort out the effects of caffeine vs other ingredients. Red Bull increased mean 24-hour and mean daytime blood pressure compared with caffeine, suggesting that the caffeine in Red Bull is not solely responsible for hemodynamic effects. Another group of researchers compared a single, 250-mL can of Red Bull vs a compounded drink containing only 240 mL bottled water and caffeine 80 mg. A study of platelet and endothelial function in 50 healthy young males found increased platelet aggregation and decreased endothelial function 1 hour after consumption of 250 mL of an unspecified energy drink containing caffeine 80 mg, taurine 1 g, glucuronolactone 600 mg, and B vitamins. Įnergy drinks that include taurine as an ingredient have also had detrimental effects reported, as have numerous case reports, often in patients with high consumption. Some experts suggest that caffeine is the likely ingredient responsible for enhanced physical or cognitive effects of energy drinks. A recent study in which subjects were given coffee containing 80 mg of caffeine or decaffeinated coffee showed that caffeinated coffee improved driving performance and reduced driver sleepiness in simulated driving. A study sponsored by Red Bull found improved driving performance and reduced driver sleepiness compared with placebo in 24 healthy volunteers. Some studies showed modest improvements in endurance, but others found no effect. A 250-mL can of Red Bull contains taurine 1 g, caffeine 80 mg, glucuronolactone (a glucose metabolite) 600 mg, B vitamins, and is available with and without sugar. The studies were small (the largest had a sample size of 20), included athletes or physically active adults as subjects, and most commonly tested Red Bull against placebo. The increasing popularity of energy drinks, which typically include taurine, has prompted multiple studies about their effect on exercise. Some research suggests that taurine in combination with branched chain amino acids may reduce muscle soreness and muscle damage after high-intensity exercise. Caffeine, but not taurine, appeared to be responsible for improved cognitive performance. Giles and colleagues compared the effects of caffeine 200 mg, taurine 2 g, a combination of these, and placebo on the cognitive performance of 48 habitual caffeine users. The influence of caffeine on these results was unclear. Check with your healthcare provider if you’re supplementing on a regular basis.More recent research on taurine with caffeine showed that this combination restored performance of sleep-deprived surgeons on simulated laparoscopy, making them feel more alert but not reducing errors. In other words, like most things, it’s personal. Taurine is generally recognized as safe (GRAS) for healthy adults. ![]() For people with heart disease, including heart failure, it is often used to aid recovery. Unrelated to athletics, taurine is known for its overall support of heart, brain, and nerve health. Another study of 11 healthy men between the ages of 18-20 pointed to its potential to improve overall exercise ability. In a study of middle-distance runners, supplementation improved overall performance. Several studies have linked taurine with improved athletic performance, including coordination, strength, and endurance. Taurine is well known to protect your heart. ![]() Thus, the confusion with “essential” amino acid.Īthletes often take taurine to improve energy and performance. Still, it is essential to many functions of the body. The main difference? Unlike the 9 essential amino acids, it doesn’t build protein. Technically? It’s an amino sulfonic acid. What Is Taurine?Īn organic compound found in large amounts in your heart, eyes, brain, and blood platelets, taurine is often called an “essential” amino acid. In addition to caffeine, taurine is a common ingredient found in energy drinks, like Monster Ultra - as well as in seafood, meat, dairy products, and eggs.īut what exactly is taurine? And what’s it doing in your energy drink? Here’s what you need to know. Have you heard of taurine? No? Take a look at the ingredients in your energy drink.
