Many of these potential benefits are associated with caffeine, a naturally occurring stimulant found in coffee beans. The amount of caffeine in a cup of coffee can vary, depending on factors ranging from the type of bean to how it's brewed.

While coffee has come to be closely associated with caffeine, today consumers can choose from a variety of caffeinated and decaffeinated options.
