Caffeine and You: What’s the connection?

If you’ve ever felt jittery or wide awake after caffeine—or needed multiple cups to stay alert—your genes may be the reason. The DNA Caffeine Sensitivity Test provides personalized insights into how efficiently your body metabolizes caffeine.

With a quick and painless cheek swab, you’ll learn whether you’re a fast or slow caffeine metabolizer and how to tailor your caffeine intake to your body’s unique needs.

The science of your caffeine sensitivity.

Your ability to process caffeine is determined by variations in the CYP1A2 gene, which influences how your liver breaks down caffeine. These variations divide people into two main categories:

  • Fast metabolizers: Your body efficiently breaks down caffeine, so its effects are less intense and shorter-lived. Fast metabolizers are less likely to experience side effects and can tolerate higher amounts of caffeine.
  • Slow metabolizers: Your body processes caffeine more slowly, meaning its effects last longer and are often stronger. Slow metabolizers are more prone to side effects like jitteriness, trouble sleeping, or increased heart rate, even with small amounts of caffeine.

The DNA Caffeine Sensitivity Test identifies whether you have the -163CC, -163CA, or -163AA variant of the CYP1A2 gene. This insight helps you understand why caffeine affects you the way it does and how to optimize your intake.
