Energy drinks are increasingly popular, but frequent consumption may pose risks to heart health, particularly among young people, according to research from the University of Virginia School of Medicine in the United States.
The study analysed data from more than 28,000 cases reported to the US Food and Drug Administration (FDA) between 2017 and 2025. Researchers examined reports involving caffeine-based energy drinks and supplements marketed to boost physical energy.
Heart-Related Emergencies Among Young Adults
According to the report, researchers found associations between the use of energy drinks or energy-boosting supplements and serious cardiovascular events, including sudden cardiac arrest and heart attacks.
The findings highlighted a range of reported heart-related problems among people aged 18 to 34. However, the study did not establish that energy drinks directly caused these events.
Researchers said further investigation is needed to understand why these products may be associated with increased cardiovascular risks.
High Caffeine Levels Raise Concerns
Energy drinks can contain substantial amounts of caffeine, while some energy supplements may contain even higher concentrations.
The American Heart Association says up to 400 milligrams of caffeine per day is generally considered safe for most healthy adults. However, individual sensitivity varies, and certain products can deliver large amounts of caffeine in a single serving.
Researchers cautioned that frequent consumption may be more concerning than occasional use, particularly for people with existing heart conditions or other cardiovascular risk factors.
Researchers Call for Caution
The study did not prove that energy drinks directly cause cardiac arrest or heart attacks. Nevertheless, researchers advised people—especially those at increased risk of heart disease—to avoid these products or limit their intake.
They also noted that energy drinks offer no essential health benefits that would outweigh potential risks for some consumers.
The findings were published in the journal Heart Rhythm and are expected to be presented at the American Heart Association’s annual meeting, according to the report.
Health note: Anyone experiencing chest pain, fainting or a racing or irregular heartbeat after consuming an energy drink should seek urgent medical assessment.
