The study found that the hearts of 17 people underwent stronger contractions after taking a drink. The drink that the people consumed contained 32 mg of caffeine for ever 100 ml and 400 mg of taurine for every 100 ml. The study found that the 17 people suffered from the stronger contractions an hour after taking the drink, reports BBC News.
The group behind the study says that it doesn’t know the exact effects an energy drink would have on a person with heart disease, but they do advise children and people with irregular heartbeats to avoid the drinks, BBC News notes.
“Until now, we haven’t known exactly what effect these energy drinks have on the function of the heart,” Dr. Jonas Dörner, from the University of Bonn, told Fox News. “There are concerns about the products’ potential adverse side effects on heart function, especially in adolescents and young adults, but there is little or no regulation of energy drink sales.”
