What to Take With & Avoid

Take With

  • Magnesium glycinate - complementary sleep mechanisms
  • L-theanine - calms racing mind
  • Consistent sleep schedule - amplifies melatonin effects

Avoid / Separate From

  • Daytime use - disrupts circadian rhythm
  • Alcohol - reduces melatonin effectiveness
  • Caffeine after 2pm - counteracts melatonin
  • Bright screens before bed - suppresses natural melatonin

Common Mistakes to Avoid

  • Taking 5-10mg when 0.5mg works - higher isn't better
  • Using nightly long-term - can suppress natural production
  • Taking too early - should be 30-60 min before target sleep time
  • Expecting it to force sleep - it signals sleep time, doesn't sedate

Pro Tips

  • Less is more - 0.3-1mg often works better than 5-10mg
  • Use for jet lag and occasional insomnia, not nightly
  • Sublingual or liquid absorbs faster than pills
  • Dim lights 1-2 hours before bed to support natural melatonin
