SAN DIEGO, Calif. (KTTC) -- A new study shows energy drinks raise resting blood pressure in young adults who don't consume caffeine regularly.

Mayo Clinic researchers alternately gave a can of a commercially available energy drink or a placebo drink to 25 healthy young adults, age 19 to 40, and monitored changes in heart rate and blood pressure. Blood pressure and heart rate were recorded before and 30 minutes after energy drink/placebo drink consumption, and were also compared between caffeine-naïve participants (those consuming less than 160 mg of caffeine per day, the amount frequently found in a cup of coffee) and regular caffeine users (those consuming more than 160 mg of caffeine per day).

Participants experienced a marked rise in blood pressure after consuming the energy drink as compared to the placebo. The effect was most dramatic in people who did not typically consume much caffeine, researchers found. Overall, the blood pressure increase was more than doubled in caffeine naïve adults after consuming the energy drink vs. placebo, they found.

Results of the study will be presented Saturday at the American College of Cardiology's 64th Annual Scientific Session in San Diego.
