Why Does Coffee Make Me Poop?

16. Not necessarily. There was a smaller study several years ago that looked at caffeine tablet intake

100-200mg--the equivalent in a large cup of brewed coffee. They found a similar effect. I don't have time to search for it, but I think this current research should have included an additional comparison group to better explore the caffeine link. Caffeine's stimulatory effects on the brain could still be quite compatible with the impacts on gastrocolic reflex. We DO know that caffeine is NOT the ONLY stimulatory chemical in coffee and tea (theanine, for example), so the old study mentioned that found that decaf coffee can have a similar effect to caffeinated coffee is not contradictory. There is nothing from this study that rules out stimulatory effects as being the cause.
