What does it mean to be a slow caffeine metabolizer?

In contrast, if you have one or two versions of the “slow” version of CYP1A2, you’re labeled a “slow” caffeine metabolizer, meaning you clear caffeine from your system about four times slower than your quick metabolizing counterparts, says Dr. Lester.

How do you know if you are a slow caffeine metabolizer?

Likely, your body is giving you signs that can clue you into where you fall on the great coffee divide.

People with anxiety or panic disorder may experience a worsening of their symptoms after consuming caffeine. Some researchers suggest that the cause of caffeine sensitivity may occur at the receptor level, where caffeine binds, or at the level of metabolism. For example, some people are slow metabolizers of caffeine.
