Answer 1

Also for example with serotonin its not that simple.
The serotonin hypothesis saying that low levels of Serotonin lead to Depression has been disproven. This is the reason why it is questionsble if antidepressants really work on its own or are just placebo. We know just too little about the connection between serotonin levels and mood, which is why it wouldnt have a use monitoring it the same way as insulin.
