Caffeine's Hidden Effect: Why Some People Buzz More Than Others

Scientists have discovered a surprising link between caffeine consumption and individual genetic variations. Shedding new light on why some people experience more pronounced effects from this stimulant.

The study, published in the Journal of Clinical Pharmacology, analyzed data from over 1,000 participants and found that genetic differences play a significant role in how caffeine is metabolized by the body. Researchers led by Dr. Emily Chen, a renowned expert in pharmacogenomics, say their findings have important implications for understanding individual responses to caffeine.

The researchers identified three key genetic variants associated with caffeine metabolism. These variants affect the activity of enzymes responsible for breaking down caffeine. This led to differences in how quickly it is absorbed and metabolized.
