There are no regulations regarding the amount of caffeine in energy drinks
“Energy drinks ‘need caffeine alert on cans’”, is the headline in the Daily Mail. The newspaper reports on a study that looked at 28 energy drinks and showed some have up to 14 times the caffeine content of a can of cola. Doctors have warned that these drinks should “carry health warnings”, so young people do not overdose on caffeine, says the newspaper.
The study is a review of the history and regulatory background of caffeine-based energy drinks in the US, including some of the “top selling US energy drinks”, which are also marketed in the UK. The authors discuss the potential for caffeine dependence and withdrawal problems that could be associated with energy drinks. This study did not measure the caffeine content of the drinks directly and did not investigate directly the effect of caffeine intake from these drinks on the body. The problems of toxicity and dependence that can follow caffeinated drink consumption, as discussed by the authors, will need further investigation before there is any proposed change in regulation.
Where did the story come from? Dr Chad J. Reissig and colleagues from the Department of Psychiatry and Behavioral Sciences at the John Hopkins University School of Medicine in Baltimore, US, carried out this research. The authors declare conflicts of interests in that they own stock in soft drinks companies. The study was supported by grants from the National Institute on Drug Abuse. It was published in the peer-reviewed medical journal: Drug and Alcohol Dependence. (more…)
