Conclusión
There is not yet enough human research to confirm that 5-HTP helps you fall asleep faster, though early animal research is encouraging.
- All 7 studies are animal or preclinical studies with no human trial data
- Evidence grade is D, indicating very limited evidence
- 5-HTP works through the serotonin system, which plays a role in sleep onset
- Human clinical trials are needed before recommendations can be made
