All About Caffeine

What Is Caffeine?

Is caffeine the same thing as coffee? Well, when you are drinking coffee, you will ingest the natural caffeine that is inside of the coffee bean. Caffeine is natural chemical found in plants (seeds or leaves) and can be used as a stimulant drug, which means it speeds up the messages travelling between the brain and the body. Caffeine works by stimulating the central nervous system (CNS), heart, muscles, and the centers that control blood pressure. These causes an increased alertness and gives most people a temporary energy boost and elevates mood.
