Summary
This study looked at whether giving high-dose vitamin D pills along with a standard bedwetting alarm helps children aged 5 to 18 who wet the bed. 262 children with low vitamin D levels took part. Half got the alarm alone, and half got the alarm plus vitamin D for 8 weeks. The goal was to see if the combination reduced wet nights more than the alarm alone.
