What is caffeine?

There are few people who are not aware of the stimulating effect that caffeine provides. We have a choice and choose caffeinated beverages for a reason. Caffeine is considered the most commonly used psychoactive drug in the world. A majority of adults consume it on a daily basis, and research is being done on its health benefits and consequences.

We may love our caffeine, but what exactly is it? Caffeine is the common name for 1,3,7-trimethylxanthine. When purified, caffeine produces an intensely bitter white powder that provides a distinctive taste in soft drinks. The word "caffeine" came from the German word kaffee and the French word café, each meaning coffee. After ingesting caffeine, it is completely absorbed within 30 to 45 minutes, and its effects substantially diminish within about three hours. It is eventually excreted so there is no accumulation in the body. Caffeine has been shown to affect mood, stamina, the cerebral vascular system, and gastric and colonic activity. But caffeine may not be for everyone. This article will discuss the health benefits and consequences of caffeine.
