Powdered Caffeine Risky, FDA Warns
The FDA noted that caffeine is a powerful stimulant and that "as little as one teaspoon of caffeine has been associated with symptoms including nausea, vomiting, anxiety, and heart palpitations," while 3 teaspoons has been associated with "chest pain, hypokalemia, elevated blood glucose, tachycardia, bigeminy, agitation, respiratory alkalosis, irregular heartbeat, and in some cases, even death."
The agency noted it could be difficult for people to accurately measure the amounts of caffeine recommended for use with common household tools. For example, one product suggests a serving size of 200 mg (approximately 1/14th of a teaspoon of the powder) and recommends using a milligram scale — something many people may not have - for accurate measurement.
