“One can of an energy beverage during one session of exercise is safe for most healthy individuals,” says John Higgins, M.D., lead author from The University of Texas Medical School in Houston. However, he states, “excess consumption and consumption with other caffeine-containing beverages or alcohol may lead to adverse effects and possibly death.”
The United States is the world’s largest consumer of energy beverages by volume, and consumption is primarily among people ages 11 to 35 years. The most common ingredient is caffeine, which ranges from 50 milligrams (mg) to 505 mg per 16-ounce serving.
