Why do energy drinks make me more jittery than coffee, even though the coffee I drink has significantly more caffeine?

Question

The title says it all really. If I drink a small Red Bull with 80 mg it makes me twitchy, but a 200 mg coffee barely even affects me.

Answer 1

Theres more than caffeine in energy drinks. They also have a loooooot of sugar and supplements like taurine and ginseng (jury is still out on if those are actually stimulants in of themselves though)

Its also about the concentration. a mug of coffee has more total caffeine than a red bull, but the red bull may have more caffeine by volume depending on how you fix your coffee.
