These studies may help guide future research in the role of genetics in modulating the acute and chronic effects of caffeine.

Caffeine sensitivity is a term that describes the efficiency of the human body to process caffeine and to metabolize it. Some of us are “fast” caffeine metabolizers and clear caffeine much faster, while “slow” metabolizers take longer to clear it from their body. 2.
