NBC News reports:
Drinking 32 ounces of energy drink is associated with potentially harmful changes in blood pressure and heart function that are beyond those seen with caffeine alone, according to a new study.
There are more than 500 energy drink products on the market, and their increased popularity is matched by a significant rise in energy drink-associated emergency department visits and deaths.
Manufacturers and fans of these products claim they are as safe as caffeine, but there is little evidence to support that claim.
