What effects do guarana and taruine from energy drink have on the human body?

Caffeine ; calming: Guarana is a main source of caffeine in energy drinks, which is a natural stimulant. I am really not sure why energy drinks have taurine, which is an Amino Acid that has a calming effect on the nervous system ; does not make people feel energetic.
