According to research, approximately 10% of the population is classified as hypersensitive to caffeine, experiencing significant side effects even with low intake. This heightened sensitivity can turn a morning coffee ritual into an uncomfortable experience, but what causes someone to be sensitive to caffeine?

According to scientific estimates, the heritability of caffeine-related traits ranges between 35% and 77%. This significant genetic component explains why some individuals can drink an espresso before bed without issue, while others get jitters from a small cup of tea, and whether caffeine tolerance can be genetic.

According to the International Coffee Organization, coffee consumption in developed countries is significantly higher than in developing countries, yet reactions vary widely across individuals. This remarkable variance explains how can caffeine affect individuals differently, a phenomenon driven by genetics, metabolism, and several other factors beyond mere intake.

According to genetic studies, approximately half the population carries a gene variant that causes them to metabolize caffeine more slowly, profoundly affecting their tolerance. So, can people be naturally tolerant to caffeine? The answer lies in your individual genetic makeup, which dictates how your body processes and responds to the stimulant from the very first sip.

According to extensive research, individual responses to caffeine have a strong genetic component, with heritability estimates ranging between 0.36 and 0.58. This variation explains why different people react to caffeine differently, experiencing unique side effects or benefits that depend on far more than just how much they consume.
