Energy drinks are a growing industry with a market value predicted to reach $61 billion by 2021.
Although commonly promoted as supplements that can boost performance and cognition, it is well known that excessive consumption of energy drinks can result in numerous and detrimental side effects.
It is estimated that about 30% of teenagers between the ages of 12 through 17 years in the United States consume energy drinks on a regular basis. Many teens admit to consuming more than two energy drinks a day. The research reported that a high percentage of teens consume 32 oz cans, which on average, contain 320mg of caffeine. Two or more cans equates to 640mg of caffeine which significantly exceeds the FDA recommended safe dose of 400 mg.
The research found that although a high level of caffeine intake can carry its own risks, it is the combination of caffeine and additional non-caffeine ingredients which are the greatest cause of concern.
The reason for this is that energy drinks are considered to be arrhythmogenic – producing or tending to produce cardiac arrhythmia/ irregular heartbeat, and have been associated with cardiac arrest, myocardial infarction, spontaneous coronary dissection, and coronary vasospasm. This association is strengthened with studies showing increased platelet aggregation, increased systolic blood pressure (SBP), and QTc prolongation which places additional pressure on the heart.
The greatest message in the current research is that energy drinks should be used with caution.
