Melatonin does not develop tolerance as per studies. However, in some patients after a good response for a few months it may become less effective than before. As per one study it may be due to the slowing down of melatonin metabolism. In this case dose reduction may be required after which melatonin again starts to work like initially.

Do bot develop tolerance.

Melatonin, is a sleep supplement, hence usually tolerance to the same is hard, but yea you can just see very little effect with this supplement. If you have sleep issues, and u wish to have a 100%solution, Homeopathy is the answer. Holistic yet effective

You do not develop tolerance on it
