Single Energy Drink Can Cause Potentially Harmful Spikes in Blood Pressure: Study

Consuming just one energy drink can cause blood pressure and stress hormone levels to spike, according to a study of young, healthy adults.

The study found young adults who consumed one 16-ounce can of Rockstar Punched experienced a 74 percent increase in blood levels of the stress hormone norepinephrine,HealthDay reports. That level is more than double an average 30 percent increase the participants experienced when they consumed a sham energy drink with the same amount of sugar, but without the natural stimulants found in Rockstar.

Stimulants in Rockstar include caffeine, taurine, guarana, ginseng and milk thistle extract.
