Vitamin D benefits for insomnia
Efficacy of low-fat milk and yogurt fortified with encapsulated vitamin D on improvement in symptoms of insomnia and quality of life: Evidence from the SUVINA trial.
Direct study on insomnia treatment
We set out to explore the relationship between vitamin D and insomnia by examining how low-fat milk and yogurt fortified with 1,500 IU of nano-encapsulated vitamin D could improve sleep issues and overall quality of life.

In our analysis, we included adults with abdominal obesity and a history of insomnia, identifying twenty-nine participants through insomnia severity questionnaires. They were split into four groups: one receiving fortified low-fat milk, another with unfortified milk, a third group consuming fortified yogurt, and a fourth with unfortified yogurt. Over a ten-week period, we tracked changes in insomnia symptoms and quality of life.

Our findings revealed that those drinking the vitamin D fortified milk experienced significant improvements in insomnia scores compared to those consuming regular milk. Additionally, quality of life assessments showed positive changes for both fortified and unfortified milk groups. However, the yogurt groups did not demonstrate significant benefits, indicating that while fortified dairy has potential, yogurt may not be as effective in this context.

In conclusion, incorporating fortified low-fat milk into our diets could help ease insomnia symptoms and enhance life satisfaction, although yogurt did not show the same promise.

Vitamin D's impact on sleep disorders
Vitamin D deficiency promoting non-24 h sleep-wake disorder: a case report.
Insights on vitamin effectiveness
We explored the case of an emmetropic woman experiencing excessive daytime sleepiness alongside insomnia, which aligned with the criteria for a non-24 h sleep-wake disorder. After traditional treatments failed, we discovered deficiencies in vitamin B12, vitamin D3, and folic acid.

Upon supplementing these nutrients, we observed a restoration of a 24-hour sleep-wake rhythm in the participant. Interestingly, this improvement occurred independently of the natural light-dark cycle, raising questions about the specific impact of vitamin D on sleep patterns.

While our study underscores how addressing vitamin deficiencies can influence sleep, it also leaves us pondering whether vitamin D plays a direct role as an essential factor or if it merely acts as a concurrent indicator of overall health.

Vitamin D and insomnia correlation
Relationship between 25-Hydroxyvitamin D, bone density, and Parkinson's disease symptoms.
Moderate relevance to insomnia treatment
We investigated the connection between vitamin D levels and insomnia among patients with Parkinson's disease (PD). In our study, which involved 182 PD patients compared to 185 healthy controls, we found that those with lower levels of serum vitamin D were more likely to experience insomnia.

Specifically, the results showed that patients with PD had significantly lower vitamin D levels than their healthy counterparts. Furthermore, those lower levels were associated with a higher frequency of falls and higher scores on the Pittsburgh Sleep Quality Index, which measures sleep disturbances.

Although we didn't identify a direct link between vitamin D and bone mineral density, the correlation with insomnia and overall sleep quality was notable. This suggests that vitamin D supplementation could serve as a beneficial strategy for improving non-motor symptoms, including sleep issues, in PD patients.

Caused serious insomnia
This supplement seemed to cause serious insomnia. After starting it post-diagnosis of osteopenia, I experienced insomnia nightly, being awake until 5 am, which was unusual for me. After stopping Citrical, my insomnia vanished, leading me to believe this product is linked to my insomnia issues.
