Research shows that timing is crucial for melatonin’s effectiveness. The optimal time to take melatonin is:
- 30-60 minutes before desired bedtime for sleep issues
- 2 hours before bedtime when adjusting to new time zones
- At local nighttime when traveling across time zones
Consistency is key – take it at the same time each night when using for sleep regulation. Avoid taking melatonin in the middle of the night if you wake up, as this can disrupt your natural sleep-wake cycle. For shift workers, timing should be adjusted to their sleep schedule, typically taking it 30 minutes before their planned sleep time, even if it’s during daylight hours.
