According to clinical studies, effective melatonin dosages vary by age and condition. For adults:

  • General sleep issues: 0.5-5mg
  • Jet lag: 2-5mg
  • Shift work: 1-3mg

It’s recommended to start with the lowest effective dose (0.5-1mg) and increase gradually if needed. Children should only take melatonin under medical supervision. Timing is crucial – take it 30-60 minutes before bedtime for optimal results. Higher doses don’t necessarily work better and may cause side effects like daytime drowsiness. A recent study suggests that long-term use should be monitored by a healthcare provider.
