The optimal melatonin dosage varies by individual and condition. Research suggests starting with the lowest effective dose:

  • General insomnia: 0.5-5mg taken 30-60 minutes before bedtime
  • Jet lag: 0.5-5mg at local bedtime
  • Children: 0.5-3mg under medical supervision only

It’s important to note that higher doses don’t necessarily mean better results. Studies indicate that lower doses (0.5-1mg) may be just as effective as higher doses while reducing the risk of side effects. Always start with the lowest dose and consult healthcare provider before use.
