Research indicates that melatonin typically takes 30-60 minutes to begin working. The timing can vary based on:

  • The form of supplement (tablets, gummies, sprays)
  • Whether it’s taken on an empty stomach or with food
  • Individual metabolism
  • Dosage amount

For optimal results, take melatonin 30-60 minutes before your desired bedtime. The effects typically last 4-8 hours, though this can vary by individual. Important note: Melatonin works best when combined with good sleep hygiene practices, such as maintaining a consistent sleep schedule and avoiding screens before bedtime.
