The FDA has issued a sternly worded safety advisory about anhydrous, or powdered caffeine, after a teenage boy from Ohio died in May from an overdose. "The difference between a safe amount and a lethal dose of caffeine in these powdered products is very small," a FDA spokesperson told the AP, unlike, say, the espresso content in those alarmingly sized Starbucks monstrosities. A teaspoon of powder, described as "nasty" tasting even in one of its more positive reviews, contains the caffeine equivalent of 25 cups of coffee. [AP]
