Why Is Powdered Caffeine Dangerous?

Powdered caffeine products are much more potent than caffeine-containing beverages like coffee, and they're dangerous because it is easy for people to consume a lethal amount of powdered caffeine, the FDA said. Just 1 teaspoon of the caffeine powder contains about the same amount of caffeine as 28 cups of regular coffee, the FDA said. "Powdered caffeine is very concentrated," said Henry Spiller, director of Central Ohio Poison Center at Nationwide Children's Hospital.
