Slow Caffeine Metabolizer? Why Coffee Gives You Anxiety
If coffee gives you anxiety, heart palpitations, or crashes, your CYP1A2 gene may be the reason. Slow caffeine metabolizers process caffeine inefficiently, allowing secondary metabolites to accumulate and overstimulate the nervous system. Paraxanthine bypasses that bottleneck entirely, delivering clean focus without the anxiety, jitters, or sleep disruption that make caffeine unreliable for millions of people.
