How is caffeine metabolised?
Caffeine is almost completely metabolized with 3% or less being excreted unchanged in urine [3,6]. The main route of metabolism in humans (70–80%) is through N-3-demethylation to paraxanthine also known as 1,7-dimethylxanthine or 17X [3,6,7] (see Fig. 1). This reaction is carried out by CYP1A2 in the liver [6].
