Vitamin D3 improves adolescent insomnia
High-dose Vitamin D Supplementation and Improvement in Cognitive Abilities, Insomnia, and Daytime Sleepiness in Adolescent Girls.
Focused insights on vitamin D3
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.

Vitamin D improves insomnia symptoms
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.
Moderate relevance due to context
We aimed to understand how vitamin D, specifically in the form of 1,500 IU nano-encapsulated vitamin D fortified in dairy products, could influence insomnia symptoms and quality of life. By conducting a case series, we selected 29 adults suffering from insomnia, particularly those with abdominal obesity. They were divided into four groups receiving different treatments over the course of 10 weeks: fortified low-fat milk, unfortified simple milk, fortified low-fat yogurt, and unfortified yogurt.
After analyzing the results, we found that participants consuming the vitamin D fortified milk experienced significant improvements in their insomnia symptoms compared to those drinking unfortified milk. However, those consuming fortified or unfortified yogurt showed no notable difference. Additionally, both groups consuming milk—fortified and simple—reported enhanced quality of life, although this was not observed in the yogurt groups.
Overall, our findings suggest that low-fat milk with added vitamin D can be beneficial for alleviating insomnia symptoms and improving quality of life, confirming its potential therapeutic role in sleep disorders.

Vitamin D3 effects on insomnia unclear
Soy isoflavones, lactobacilli, Magnolia bark extract, vitamin D3 and calcium. Controlled clinical study in menopause.
Combined treatment complicates results
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.

Improved mood
I decided to take vitamin D due to its positive effects on my body and my love for the sun. I often feel sluggish and down during autumn, and I've noticed significant improvements after taking these vitamins. I chose a dosage of 2000 IU, as I hardly go outside and suffer from poor mood in colder months. Taking one small capsule in the morning has really helped lift my spirits and combat insomnia.

Reduced insomnia
Quickly resolves vitamin D3 deficiency. My well-being has improved; my skin looks better, and I've alleviated nervousness and insomnia.

Improved mood
Recent studies indicate that vitamin D3 deficiency is commonplace. Sun exposure alone often isn't enough, as our diets may lack sufficient amounts. I take 2000 IU daily which noticeably improved my mood and reduced insomnia. After three weeks of use, I woke up easier, felt less irritable, and my hair condition improved. I strongly recommend taking it in the morning!

Supports health
Vitamin D3 is vital for immunity and overall health. It reduces the risk of viral diseases and respiratory infections. I believe it helps manage insomnia and improves mood. Taking it with vitamin K2 and magnesium enhances absorption. Due to limited sunlight exposure, I opt for additional D3 supplementation. I recommend NOW brand for its quality and price!
