The Food and Drug Administration (FDA) is reporting that 5-Hour Energy, a 2-oz. bottle of highly-caffeinated liquid known as a 'shot,' may be linked to 13 deaths over the past four years.
The findings come just one month after the FDA reported similar dangers associated with Monster Energy, an energy drink that is popular with teenagers and adults alike. Five people died due to medical complications after consuming the beverage.
The New York Times reports that 5-Hour Energy has been associated with potentially life-threatening injuries such as heart attacks, heart problems, convulsions, and even a spontaneous abortion. The FDA has received 90 adverse reports.
The company that makes 5-Hour Energy doesn't list the amount of caffeine included in its product on the label, but Consumer Reports states that the shot may have about 215 milligrams of caffeine, as well as other ingredients like taurine and high levels of certain B vitamins. In comparison, an 8-oz. cup of coffee can contain anywhere from 100-150 milligrams of caffeine.
