Can someone Explain it Like I’m 5 any reasons to NOT take caffeine pills in replacement of coffee drinks and such?
Caffeine pills are pure and released quickly. Natural beverages contain other substance that may act like caffeine, but are typically more mild. For instance, coffee contains theobromine, and tea contains theanine. Both of these moderate the caffeine jolt. My experience with pills is that they are harsh, and give me the jitters.
The biggest danger with caffeine pills is overdose. It's almost impossible to OD on coffee or tea (because they're mostly water) but with pills that's a real danger.
