結論

            
            
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
