A new study from the United States shows that energy drinks and other products with caffeine may be linked to serious heart problems in young adults. Researchers looked at more than 28,000 health reports sent to the Food and Drug Administration (FDA) between 2017 and 2025. They found that heart problems such as cardiac arrest, heart attacks, and irregular heartbeats were reported much more often after people used energy drinks or stimulant supplements. Almost half of these cases involved people aged 18 to 34.

The main reason for these problems seems to be the high amount of caffeine and other strong ingredients in energy drinks and similar products. These ingredients are different from those in regular coffee, and the total amount can be hard to know, especially if people drink several products or mix them with supplements.

Because of this research, doctors are warning young people to pay attention to how much caffeine and stimulants they use. If someone feels chest pain, faints, or has a fast heartbeat after using these drinks, they should see a doctor immediately. More research is needed to find out exactly how these products affect the heart.
