Tag: Coffee genetics

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.

Genetics play a significant role in how our bodies process stimulants, leading to vast individual differences in caffeine response. This means for some, the question, 'can you be non-responsive to caffeine?' is a very real, scientifically-backed phenomenon, resulting in little to no stimulant effect from a normal dose.

Did you know that even decaffeinated coffee contains a small amount of caffeine, with the FDA requiring only 97% removal? This fact raises a fascinating question: can coffee beans have no caffeine at all?
