I want to do a blind controlled experiment on myself to learn whether melatonin pills have any effects on me. I bought some empty gelatin capsules. I am going to fill some of them with rice and put pieces of melatonin pill in others.
Melatonin pills instruction says I should take it 30-40 minutes before going to bed. Now I wonder if the timing is the same when stuck inside gelatin capsules. Also is it possible that melatonin pills stuck inside capsules will get to a later stage of the digestive tract than they should and thus will not work.
