Vitamina D per Insonnia
A Evidenze Più grandi trial clinici mostrano in modo costante benefici significativi.Basato su 53 studi (3 meta-analyses, 1 RCT) con 685,942 partecipanti totali. I risultati sono contrastanti tra gli studi.
In sintesi
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
