🧬 Your Genetics Play a Role
Your response to coffee may depend partly on a gene called CYP1A2, which affects how quickly your body processes caffeine.
Fast metabolizers break down caffeine quickly and can usually tolerate more coffee.
Slow metabolizers process caffeine more slowly and may experience jitters, sleep problems, or increased heart risks with high intake.
You don’t need genetic testing to figure this out—simply pay attention to how your body responds.
