En conclusion

Tryptophan shows promising signs for helping people fall asleep faster, supported by a strong biological rationale, though the studies so far have been quite small.

  • 84% of 19 studies show positive effects — a very consistent finding
  • Works through conversion to serotonin and then melatonin in the brain
  • Total participant count of only 96 limits the strength of conclusions
  • Includes 1 meta-analysis and 1 RCT — larger trials are needed
