Melatonin has a very short Half-Life

Hello there, thanks for your question on HCM.
Melatonin is rapidly acting hormone.
It is having half life of 30-45 minutes. This means it is having peak action in first 30-45 minutes.
It will remain in the body for 10-11 hours.
So it will stay in your system for 10-11 hours after ingestion.
