People who took the 5 mg dose elevated whole sleep time and sleep effectivity considerably regardless if sleep was scheduled within the daytime or night time.

The researchers comment that bigger trials with different melatonin doses would wanted to be performed to determine if a dose between 0.3 and 5mg may additionally work as successfully.
