Energy Drinks May be Dangerous to Some
By Meghan Smith

A recent study shows that the caffeine content of energy drinks is far above the FDA limit set for carbonated colas. That could pose serious risks for certain types of people.

Researchers say those with hypertension, who are pregnant, or who suffer from anxiety attacks should limit the amount of caffeine they take in.

The FDA doesn't currently regulate the amount of caffeine in energy drinks, and the researchers say warning labels should accompany the beverages.

For all colas tested, caffeine content ranged from 18 to 48 milligrams—within the FDA’s 65 milligram-per-serving limit.

Energy drinks ranged from 33 to 77 milligrams, with So-Be "No Fear" coming in the highest at 141 milligrams of caffeine per serving.
