We explored the connection between vitamin D levels and the frequency of upper respiratory tract infections (URTI) in physically active individuals throughout different seasons. In our research, we observed over 1,600 military recruits during their basic training, noting that only 21% were vitamin D sufficient during winter. Alarmingly, those who had sufficient vitamin D levels were found to be 40% less likely to experience URTIs compared to their deficient counterparts, suggesting that maintaining adequate vitamin D may be crucial for better respiratory health during demanding training periods.
Building on these findings, we conducted a follow-up study with 250 recruits, where we implemented various vitamin D supplementation strategies. Participants received either a placebo, simulated sunlight exposure, or oral vitamin D3 supplementation. The results were promising: vitamin D helped alleviate the severity of URTI symptoms and significantly reduced the number of days experiencing a cold. Notably, both sunlight and dietary supplementation were equally effective in boosting vitamin D levels and improving outcomes.
Overall, achieving vitamin D sufficiency can markedly reduce the burden of URTIs, particularly in physically demanding scenarios such as military training.

We investigated the potential connection between vitamin D deficiency and allergic proctocolitis (AP) in infants. Our study involved a careful comparison of vitamin D levels in infants diagnosed with AP against those of healthy infants. This meticulous, prospective approach allows us to draw insightful conclusions about how vitamin D might be influencing allergic conditions.
We found that vitamin D levels were noticeably lower in infants suffering from AP compared to their healthy peers. Notably, a significant percentage of AP patients—34.7%—were found to be vitamin D deficient or insufficient. Furthermore, the study revealed that infants with vitamin D levels below 40.75 mcg/L were 3.5 times more likely to develop AP.
Our findings suggest an intriguing association between vitamin D deficiency and allergic proctocolitis, hinting that the rising rates of such allergies may be influenced by environmental factors. It appears crucial that we assess vitamin D levels in infants diagnosed with AP, as this could contribute to better understanding and management of the condition.

We explored the connection between vitamin D levels and upper respiratory tract infections (URTIs) among military recruits during their training. This observation spanned across different seasons and included over 1,600 recruits. Our aim was to understand how achieving sufficient vitamin D levels could potentially impact the frequency and severity of colds among physically active individuals.
In an additional phase of the research, we conducted a randomized controlled trial with 250 male recruits. They received either a placebo, simulated sunlight exposure, or oral vitamin D3 supplements during winter. This comparison allowed us to see if these methods effectively increased vitamin D levels to a sufficient status of 25(OH)D at 50 nmol/L or higher.
Notably, our findings showed that only 21% of recruits had adequate vitamin D during winter, yet those who did were 40% less likely to suffer from URTIs. Furthermore, both vitamin D supplementation strategies similarly helped nearly all participants achieve sufficient levels. Vitamin D supplementation notably reduced the severity of URTI symptoms by 15% and the number of days with URTIs by 36% compared to placebo.
While the supplementation strategies did not significantly alter other immune factors, such as salivary secretory immunoglobulin A, the overall reduction in respiratory infections indicates a beneficial effect of maintaining vitamin D sufficiency during military training.

Vitamin D3 improves depressive symptoms
We conducted a double-blind randomized clinical trial to explore the effects of vitamin D3 supplementation on depression. Our study involved 56 adults with mild to moderate depression, who were assigned to either a vitamin D group or a placebo group. Over the course of eight weeks, the vitamin D group received a high dose of 50,000 IU cholecalciferol every two weeks, while the control group received a placebo.
After the treatment period, we observed that the participants who received the vitamin D3 experienced a significant reduction in depression severity, as measured by the Beck Depression Inventory-II. Interestingly, this improvement in mood occurred independently of any changes in inflammatory biomarkers like IL-1β, IL-6, and hs-CRP, which we also assessed during the study.
This indicates that while vitamin D supplementation may positively impact depressive symptoms, its effects are not directly linked to the inflammatory markers we evaluated. Our findings suggest that vitamin D3 could be a helpful addition to depression treatment strategies, particularly in individuals with low vitamin D levels.

We conducted a rigorous study to explore how vitamin D3 supplementation might influence headaches in people suffering from migraines. By utilizing a well-structured, placebo-controlled, double-blind design, we included 80 participants with episodic migraines, assigning them either a daily dose of vitamin D3 or a placebo for 12 weeks.
After the study, we observed significant improvements in those receiving vitamin D3. Participants reported fewer headache days each month, shorter headache durations, and less severe pain overall. They also used fewer pain relievers compared to those on placebo, showcasing the potential benefit of vitamin D3 in managing migraine symptoms.
Our findings suggest that vitamin D3 not only aids in reducing headache frequency but may also play a role in addressing inflammation, as evidenced by reduced levels of certain inflammatory markers in the blood. This highlights its possible therapeutic value for migraine sufferers, indicating that a daily dose could make a meaningful difference in their lives.

We aimed to understand how oral supplementation of 25-hydroxyvitamin D, a key metabolite of vitamin D3, influences influenza A virus infection in mice. In our study, mice were given a diet enriched with a high dose of 25(OH)D before they were exposed to the influenza virus.
The results were promising. Mice that received the vitamin D3 supplement showed significantly lower viral levels in their lungs compared to mice that were fed a standard diet. Furthermore, we noticed a decrease in certain pro-inflammatory cytokines, namely IL-5 and IFN-γ, which are involved in the body's inflammatory response to infection. Importantly, we found that the anti-inflammatory cytokines did not see a significant increase.
These findings suggest that 25(OH)D can help to suppress excessive inflammatory responses and may reduce both the replication of the virus and the overall severity of influenza in this mouse model. It opens the door to further exploration on vitamin D3's role in combating influenza in humans.

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 D supports bone health
We aimed to uncover the relationship between vitamin D levels and bone mineral density (BMD) in menopausal women, a group particularly vulnerable to osteoporosis due to hormonal changes. To achieve this, we conducted a thorough study involving 32 participants, all of whom were menopausal women without a history of hormone replacement therapy or vitamin D supplementation.
Throughout our research, we measured the participants' serum vitamin D levels and evaluated their bone density using a technique called radiofrequency echographic multi-spectrometry (REMS). Our findings revealed a significant positive correlation between vitamin D levels and BMD—indicating that higher vitamin D levels were associated with better bone density.
This suggests that maintaining adequate vitamin D levels might be crucial for preserving bone health during menopause. Given the particular vulnerability of this demographic to osteoporosis, our study underscores the importance of monitoring and potentially supplementing vitamin D to support bone health in menopausal women.
Overall, we believe our findings contribute to the conversation around menopause management by highlighting the role of vitamin D in promoting healthier bones, and we suggest that REMS could serve as a valuable tool in assessing these changes in postmenopausal women.

We investigated the influence of calcitriol, the active form of vitamin D, on experimental autoimmune encephalomyelitis (EAE), an animal model akin to multiple sclerosis. Our study involved twenty-eight mice divided into four groups, allowing us to compare outcomes between those with and without EAE, as well as those receiving calcitriol treatment.
We found that, in mice with EAE, inflammation indicators such as interleukin-17 (IL-17) significantly increased, while transforming growth factor beta (TGF-β) levels decreased compared to healthy controls. Upon treating the EAE group with calcitriol, we observed a reversal of these changes, suggesting a substantial immunomodulatory effect, which eased symptoms typically associated with EAE.
Notably, we also noticed that calcitriol enhanced gene expression for interleukin-9 (IL-9) in both healthy and EAE mice. Overall, our findings support the notion that calcitriol holds promise as a potential treatment to alleviate the symptoms of multiple sclerosis through its anti-inflammatory properties.

We investigated how vitamin D3 supplementation impacts cholesterol levels in pediatric patients with obesity. During our study, we divided 723 children into two groups: one received vitamin D3 supplements, while the other received a placebo. This allowed us to comprehensively assess the relationship between vitamin D and metabolic health, especially focusing on high cholesterol.
What we found was promising. After introducing vitamin D3 to the participants, we observed a significant drop in various lipid levels among those who received the supplements compared to those who were on the placebo. Specifically, there were notable reductions in total cholesterol, triglycerides, and low-density lipoprotein (LDL), alongside improvements in high-density lipoprotein (HDL).
Our results highlight that vitamin D3 not only boosted vitamin D levels but also positively influenced cholesterol metabolism. This suggests that supplementing with vitamin D could be a helpful strategy for managing high cholesterol, particularly in children struggling with obesity. Overall, our findings underscore the potential of vitamin D in improving metabolic health in younger populations.

Vitamin D's limited effect on kidney stones
We conducted a clinical trial to explore how different vitamin D treatment protocols affect kidney stones in patients who frequently experience them and have low vitamin D levels. We involved 62 participants, all with serum vitamin D levels between 10 to 20 ng/ml, and split them into two groups: one received 2000 IU of oral vitamin D daily for 12 weeks, while the other took 50,000 IU weekly for 8 weeks.
Our results showed that both treatment approaches led to a significant increase in 24-hour urine calcium. However, we observed no notable difference between the two therapies regarding this measure. Importantly, while there was an increase in 24-hour urine calcium, neither treatment affected the supersaturation levels of calcium oxalate or calcium phosphate, which are critical in the formation of kidney stones.
We also noted a significant rise in serum 25-hydroxyvitamin D levels, with the weekly regimen showing a greater increase. Alongside these changes, parathyroid hormone levels decreased in both groups. Ultimately, while vitamin D supplementation did elevate urine calcium levels, it did not enhance supersaturation factors that contribute to kidney stone formation, indicating that the benefits of vitamin D in this context may be limited.

We conducted a study to see if high-dose vitamin D3 could improve vascular health and reduce fatigue in individuals suffering from chronic fatigue syndrome (CFS). This was a well-structured trial involving 50 participants, all of whom met specific diagnostic criteria for CFS. Participants were divided into two groups: one received 100,000 units of vitamin D3 every two months, while the other received a placebo over a period of six months.
Despite a noticeable increase of 22 nmol/L in vitamin D levels for those who received the treatment compared to the placebo group, we found no significant benefits. There was no change in arterial stiffness, a key vascular health indicator, nor improvements in overall fatigue as measured by the Piper Fatigue scale.

We aimed to understand how vitamin D influences bone health and helps combat osteoporosis, a condition that weakens bones. In our study, we used various mouse models, including those that mimic a deficiency in active vitamin D. Through a range of advanced methods, we assessed how changes in vitamin D levels affected bone structure and metabolism.
The research revealed that insufficient vitamin D led to a drop in Sirt1, a gene that plays a crucial role in maintaining bone density. This lack of Sirt1 resulted in increased bone loss. However, when we boosted Sirt1 levels in bone stem cells, we observed a reversal in bone loss. This improvement happened because higher Sirt1 levels reduced oxidative stress, slowed down aging processes in bone cells, and enhanced new bone formation while curbing bone resorption.
Additionally, our findings indicated that vitamin D directly stimulates Sirt1 expression in these stem cells, which is vital for bone health. We also explored the effects of resveratrol, a natural compound known for activating Sirt1, and found it helped alleviate osteoporosis symptoms linked to vitamin D deficiency by enhancing the relationship between Sirt1 and another protein called PGC1α, which supports bone formation and energy metabolism.
This research underscores the importance of the vitamin D-Sirt1/PGC1α axis in bone metabolism, providing insight into how vitamin D can serve as a target for osteoporosis prevention and treatment.

We also explored the effects of resveratrol, a natural compound known for activating Sirt1, and found it helped alleviate osteoporosis symptoms linked to vitamin D deficiency by enhancing the relationship between Sirt1 and another protein called PGC1α, which supports bone formation and energy metabolism.
This research underscores the importance of the vitamin D-Sirt1/PGC1α axis in bone metabolism, providing insight into how vitamin D can serve as a target for osteoporosis prevention and treatment.

Vitamin D may reduce prostate cancer mortality
We set out to understand how vitamin D signaling within prostate cancer tumors might impact patient outcomes, particularly the risk of developing lethal forms of the disease. In our exploration, we analyzed data from 404 men with primary prostate cancer over a long follow-up period, assessing specific gene expressions linked to vitamin D in their tumor tissues.
Our findings revealed a noteworthy trend: the activation of vitamin D signaling in tumors was associated with a lower chance of progressing to lethal prostate cancer. Specifically, men with higher scores indicating active vitamin D signaling had a significantly reduced risk of metastasis or prostate cancer-related death compared to those with lower scores.
Interestingly, this protective association appeared to be stronger in individuals with predicted higher levels of vitamin D in their blood and those who had a body mass index of 25 or higher. With our research providing a clearer picture of how vitamin D functions within tumors, we believe there’s a solid basis for considering vitamin D interventions as potential strategies to enhance survival outcomes for prostate cancer patients.

We investigated the potential of vitamin D3, also known as cholecalciferol, in combating cancer while addressing concerns about its toxicity at higher doses. This study focused on enhancing the effectiveness of vitamin D3 through a clever method called liposomal encapsulation, which helps minimize side effects.
We prepared liposomal vitamin D3 (VD-LP) and conducted various tests to understand its capabilities. We found that this encapsulated form not only maintained high efficiency but also demonstrated improved stability. Our analyses showed that VD-LP had strong effects against cancer cells from colorectal, breast, and prostate cancers. Remarkably, it affected gene expression in immune cells, boosting elements that help fight infections and support the body's defenses.
Notably, VD-LP did a great job slowing tumor growth in mice and improved their survival rates without causing adverse effects like hypercalcemia, which is often a concern with regular vitamin D3 use. This evidence indicates that liposomal encapsulation of vitamin D3 could offer an effective cancer treatment strategy while minimizing unwanted side effects.
We believe this may pave the way for further research and clinical applications, showcasing vitamin D3 as a valuable addition to cancer therapy.

Vitamin D and nausea in gastroparesis
We delved into an intriguing question: how do low vitamin D levels affect nausea in people experiencing gastroparesis, a condition that slows gastric emptying? By measuring the vitamin D levels of patients from the Gastroparesis Clinical Consortium Registry, we aimed to uncover the relationships between vitamin D, nausea, and gastric function.
Our findings revealed that over half of the patients had low vitamin D levels, specifically 56.1% of the 513 individuals studied. We observed a clear association between these low levels of vitamin D and increased experiences of nausea and vomiting. This was particularly notable in patients with delayed gastric emptying, where those with low vitamin D levels reported significantly more nausea.
While the study showed a correlation, it did not address whether supplementing with vitamin D could directly alleviate these symptoms. Instead, we found that lower vitamin D levels also related to a greater retention of food in the stomach after meals, which hints at a connection to gastric neuromuscular dysfunction. Overall, our study emphasized a noteworthy link between vitamin D and nausea but stopped short of confirming any direct treatment benefits.

We explored the impact of vitamin D3 levels on bone pain that patients experience after undergoing unicompartmental knee arthroplasty (UKA). The study involved 240 participants who were divided into three groups based on their vitamin D status—some received treatment before surgery, some after, and others had normal levels to begin with.
By administering vitamin D3 in three doses, we aimed to see if correcting deficiencies could alleviate post-operative bone pain. Throughout the recovery period, we measured pain levels using the visual analog scale at various intervals after the surgery.
Our findings clearly demonstrated that patients who corrected their vitamin D3 deficiency before surgery reported significantly better pain control after the operation compared to those who were treated afterwards or those who started with adequate levels. This highlights the importance of testing and addressing vitamin D status prior to orthopedic procedures, showing that it is a modifiable risk factor affecting recovery.

We sought to understand the role of vitamin D3 supplementation in alleviating chronic low back pain (CLBP). In a single-arm, open-label study at a tertiary care hospital, we worked with 68 patients suffering from CLBP for at least three months, each demonstrating a significant pain level on a visual scale alongside low vitamin D levels.
Participants received 60,000 IU of vitamin D3 weekly for eight weeks. We tracked pain intensity and functional disability at various stages: at the outset, and then at two, three, and six months post-supplementation. Notably, we witnessed a remarkable increase in vitamin D levels from an average of 12.8 ng/mL to 36.07 ng/mL in those eight weeks, with 66% of participants achieving normal vitamin D levels.
The benefits didn’t stop there. Patients reported a significant drop in their pain scores at all follow-up periods, improving from 81 to 36 on the scale. Functional ability also saw enhancement over time, proving the positive influence of vitamin D3 on both pain and everyday activities.
Overall, our findings suggest that vitamin D3 supplementation can be an effective avenue for improving pain intensity and functionality in individuals with low back pain, warranting further investigation through controlled clinical trials.

We explored the potential benefits of vitamin D3 supplementation in alleviating knee pain associated with osteoarthritis (OA). In this open-label clinical trial, we assessed the effects of daily doses of 4000 IU vitamin D3 over three months in 80 patients suffering from knee OA.
Our findings revealed notable improvements in pain levels and overall physical function. The patients showed significant reductions in pain scores measured by the Visual Analog Scale (VAS) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) subscores after the treatment period. Remarkably, 86.7% of those treated responded positively to the therapy.
Interestingly, we observed changes in systemic cytokine levels: while some pro-inflammatory markers increased, others, including TNF-α and IL-17, showed significant reductions. This suggests that vitamin D3 not only helps with pain relief but also may influence inflammatory processes in the body.
Overall, our results indicate that vitamin D3 supplementation could be a promising therapeutic option for managing symptoms of knee OA. Nonetheless, future research should further investigate the role of specific inflammatory mediators, like IL-33, in the progression of knee osteoarthritis.

We explored how Vitamin D3 impacts autoimmune thyroiditis, a specific autoimmune disorder. In this study, researchers established a mouse model of experimental autoimmune thyroiditis (EAT) to see how Vitamin D3 could influence this condition. After eight weeks of treatment, they assessed thyroid health and immune response through various methods, including staining tissues and measuring hormone levels.
Our observations revealed that administering Vitamin D3 helped reduce damage to the thyroid and decreased the presence of inflammatory cells within the thyroid. This treatment also led to lower levels of thyroid hormones and autoimmune antibodies in the blood, highlighting its positive effect on thyroid function. Additionally, Vitamin D3 appeared to promote the regulatory T cell (Treg) subset while decreasing the levels of Th17 cells, which are often involved in autoimmune processes.
Mechanistically, the study found that Vitamin D3 triggered specific pathways that influence Treg cell activity and survival. Notably, it activated a signaling pathway involving YAP and JAK/STAT, which are crucial for immune cell regulation. These findings suggest that Vitamin D3 could play a significant role in balancing immune responses in autoimmune thyroiditis, making it a promising candidate for further research and potential treatment strategies.
