Vitamin D benefits for insomnia
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 D3 improves adolescent insomnia
We studied how high-dose vitamin D3 supplementation might affect insomnia in adolescent girls. Over nine weeks, 940 participants received a weekly dose of 50,000 IU of vitamin D3 while we tracked changes in their sleep patterns.
Interestingly, we observed a notable reduction in insomnia rates after the treatment. The number of girls reporting insomnia dropped from 15.0% to 11.3%, indicating that this vitamin can potentially improve sleep quality.
We also noticed a slight decrease in daytime sleepiness, with cases falling from 15.6% to 14.7%. Furthermore, those experiencing both insomnia and sleepiness saw a decline from 8.0% to 6.1%.
These findings suggest that high-dose vitamin D can play a significant role in alleviating sleep issues among adolescent girls. However, further studies are needed to see if these effects are consistent across diverse age and gender groups.

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.

I started taking vitamin D3 in Moscow without testing my levels, as I knew there was a deficiency here. After a week or two of taking 50 mcg daily, my insomnia improved significantly; I no longer needed sleeping pills. My monthly cycle also stabilised. Within three months, my herpes outbreaks decreased considerably.

Restored sleep
I appreciate Solgar's quality; their Vitamin D3 has improved my sleep. Initially, I struggled with insomnia, but it has since been restored, boosting my energy and mood. I believe that taking less than 1000 IU daily is insufficient to resolve deficiencies, but caution is needed to avoid overdose, which can lead to insomnia.

A wonderful side effect of taking Vitamin D is that it has helped my mother-in-law, who suffered from insomnia for forty years, finally sleep at night. We were surprised, as we learned that vitamin D plays a role in sleep regulation. I believe vitamin D is crucial for our health, yet many doctors overlook testing for its levels in patients, focusing on symptoms instead. A daily intake of 1,000 IU is recommended, preferably in oil form for better absorption, alongside vitamin K2.

We conducted a controlled study to understand the effects of vitamin D3, along with other components, on insomnia and other symptoms experienced by menopausal women. Over 24 weeks, participants took either a formulation that included vitamin D3 or a standard calcium and vitamin D3 supplement.
Throughout the study, we tracked various symptoms like insomnia and mood changes. We found that while the formulation containing vitamin D3 showed some promise for addressing hormonal symptoms such as hot flashes and mood disturbances, the specific impact of vitamin D3 on insomnia was not isolated enough to draw definitive conclusions.
Importantly, participants who took the formulation reported improvements in overall well-being and satisfaction compared to those on regular calcium and vitamin D3. However, determining the isolated benefits of vitamin D3 alone remains challenging, as it was part of a broader mix of ingredients aimed at alleviating multiple menopause-related symptoms.
Thus, while our findings highlight the potential benefits of a comprehensive approach, the role of vitamin D3 specifically on insomnia is still uncertain. Further studies would be needed to clarify its effectiveness.

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.

Essential supplement
I will not elaborate on the importance of vitamin D3. My family and I take 1000 mg daily for prevention. Solgar’s vitamin D3 is effective and of high quality. I prefer it in liquid form; taking it with a fat source prevents insomnia. We also take it alongside vitamin K2, ensuring we have enough energy throughout the day.

Research shows that vitamin D3 is more effectively absorbed and has less risk of overdose. This deficiency contributes to insomnia, causing lethargy and poor daytime performance.
