Many people can't get going in the morning without something caffeinated. Watch out for this stuff though.

Pure, powdered caffeine is a thing now. A teaspoon of this stuff is roughly the same as drinking 28 cups of coffee and it's been linked to at least two deaths. The Food and Drug Administration has sent letters to distributors of this stuff telling them their product is dangerous.

As a result of those letters, most manufacturers have halted or tightly limited the sale of this "super-caff." The powder is added to other drinks for quick energy boosts or as a weight loss measure. According to the FDA though:

"Volume measures, such as teaspoons, are not precise enough to calculate how many milligrams of caffeine are in the serving size.

Measure wrong, you die? Yeah, no thanks.
