Conclusión

The evidence on vitamin D for insomnia is mixed — low vitamin D levels are associated with poor sleep, but taking vitamin D supplements does not consistently improve insomnia symptoms.

53 studies with 685,942 participants, though mostly from observational research
Low vitamin D levels are associated with poor sleep in population studies
Supplementation results are inconsistent — not a reliable standalone sleep aid
May be most relevant for people who are vitamin D deficient
