Research indicates that melatonin typically begins working within 30-60 minutes after ingestion. However, several factors affect its efficacy:
- Individual metabolism rates
- Current sleep-wake patterns
- Form of melatonin (immediate vs. extended-release)
- Presence of food in stomach
For optimal results, take melatonin 30-60 minutes before your desired bedtime. The effects usually last 4-8 hours, though this can vary by individual. Regular use may be needed for 1-2 weeks before noticing significant improvements in sleep patterns, particularly for chronic sleep issues.
