結論

            
            
There is insufficient evidence to determine whether vitamin D helps with staying asleep through the night — only one observational study exists on this specific topic.

                    Only 1 observational study available — far too little evidence for conclusions

  • 
                    
                    The study found mixed results for vitamin D and sleep maintenance

  • 
                    
                    No RCTs or meta-analyses exist for this specific use
                
    • 
                
                
  • 
                    
                    Observational data cannot establish whether vitamin D directly helps
