American Heart Association energy drink study
The gist
The American Heart Association analyzed more than 28,000 FDA adverse-event reports from 2017-2025 and linked energy drinks to serious heart conditions far more often than other products.
The findings are preliminary and don't prove cause, but regular users can quickly exceed recommended caffeine limits.
