结论
There is currently not enough evidence to determine whether glycine helps you fall asleep faster — only one very small study with mixed results has been identified.
- Only 1 study with 5 participants — far too little to draw conclusions
- Grade D evidence indicates very limited research on this specific use
- The available study was not specifically designed to test glycine for sleep onset
- Glycine's broader sleep benefits (see insomnia evidence) do not automatically apply to sleep onset
