This is precisely what I was getting at. too much caffeine remedy reddit. Additionally, the clearance of many foreign molecules from the bloodstream is well modeled by exponential decay and thus can be described by a single parameter (either the half life or the rate constant).

Among elderly individuals (age 65+), ability to metabolize caffeine decreases by 33% compared to adults; from a rate of 1.5 ml/min to 1.0 ml/min. It uses the popular caffeine+theanine stack, a novel purine alkaloid called Dynamine, and delayed and extended release caffeine to produce a smooth, all-day energy and focus.
