Toxicity of energy drinks

Area of Science:

• Pediatric Health
• Adolescent Medicine
• Toxicology

Background:

• Energy drinks and shots have surged in popularity.
• Caffeine is the primary active ingredient, with excessive intake linked to acute toxicity like tachycardia and seizures.
• Chronic effects of high caffeine doses in adolescents remain largely unknown.

Purpose of the Study:

• To review recent literature on adverse events associated with energy drink consumption in children and adolescents.
• To highlight the potential risks of high caffeine doses and co-ingested ingredients.
• To emphasize the need for further research and potential regulation.

Main Methods:

• Review of recent and significant literature on adverse events.
• Analysis of reported health issues linked to energy drink consumption.
• Synthesis of findings regarding caffeine and other ingredient toxicity.

Main Results:

• Excessive caffeine intake can cause acute intoxication, including cardiac arrhythmias and seizures.
• Co-ingestion with ethanol is associated with increased risk-taking behaviors and impaired driving.
• The toxicity profiles of other common energy drink ingredients (e.g., taurine, niacin) are not well-defined.

Conclusions:

• Energy drinks represent a novel exposure for adolescents, distinct from prior caffeine studies.
• High caffeine doses combined with poorly understood ingredients necessitate urgent safety research.
• Characterizing health effects may lead to the regulation of pediatric energy drink use.
