CYP1A2 accounts for approximately 95% of caffeine metabolism and demonstrates wide variability in enzyme activity between individuals.Caffeine metabolism occurs primarily in the liver, catalyzed by hepatic microsomal enzyme systems (Grant et al.Caffeine (1,3,7-trimethylxanthine) is a methylxanthine derivative with a molecular formula of C8H10N4O2 [9]. It is considered to be an alkaloid compound as it is a metabolite of nitrogen metabolism [10].

It is found in coffee, tea, cola, cocoa, guarana, yerba mate, and over 60 other products.

A recent recommendation by the American Association for the Study of Liver Disease suggests that either caffeinated or decaf coffee can be consumed to receive liver benefits.Gradual tapering of caffeine, reducing intake by 25% to 50% every few days, is the most effective method to prevent withdrawal symptoms, particularly in heavy users.While you can minimize the effects of caffeine by drinking water, switching to decaf and moving around, again, there’s no proven method on how to flush caffeine out of your system quickly.
