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.

Vitamin D supports depression management
We conducted a double-blind, randomized, placebo-controlled trial to explore how cholecalciferol, a form of vitamin D, influences depressive symptoms in individuals suffering from type 2 diabetes mellitus (T2DM). This clinical study lasted for 12 weeks and involved participants who were either given a daily dose of 4000 IU of cholecalciferol or a placebo.
Throughout the study, we measured various factors, including the participants’ depression levels using the Beck Depression Inventory-II, as well as important biological markers like C-peptide, serotonin, and neurotrophin-3.
Our findings showed a significant reduction in depression scores among those taking cholecalciferol compared to the placebo group. Additionally, we observed a notable increase in C-peptide levels, which may indicate some metabolic benefits, although no significant changes were found in serotonin and neurotrophin-3 levels.
Ultimately, while cholecalciferol appears to alleviate mild to moderate depressive symptoms in T2DM patients through improved C-peptide levels, its impact on serotonin and neurotrophin-3 remains unclear. This highlights vitamin D as a potentially helpful option for managing depression alongside diabetes.

We examined the connection between vitamin D deficiency (VDD) and depression in patients with chronic kidney disease (CKD). Our research, which utilized a large database from the TriNetX network, involved over 17,900 matched CKD patients aged 50 and older. They were divided into two groups based on their vitamin D levels: those with deficiency (20 ng/mL or lower) and those with adequate levels (30 ng/mL or higher).
The findings were striking. We discovered that those with VDD had nearly double the risk of developing depression within a year compared to those with sufficient vitamin D levels. This risk was especially pronounced in men and remained consistent across different stages of CKD. Even patients who had borderline low vitamin D levels faced an increased chance of depression.
Our study suggests that maintaining adequate vitamin D levels might be crucial for mental health in CKD patients. However, we also recognize the need for further randomized trials to definitively establish whether vitamin D supplementation can help prevent depression in these individuals. The implications of our findings could pave the way for new approaches to managing mental health in patients dealing with CKD.

Vitamin D and Magnesium Aid Depression
We conducted a study to evaluate whether supplementing with magnesium and vitamin D could help alleviate mild-to-moderate depressive symptoms in individuals suffering from long-COVID. The clinical trial included 60 participants, aged 52.8 years on average, who had been diagnosed with hypomagnesemia, vitamin D deficiency, and mild-to-moderate depression.
Participants were divided into two groups: one received magnesium chloride along with vitamin D, while the other group only received vitamin D. Over four months, we monitored the effectiveness of these supplements in reducing depressive symptoms, using the Beck Depression Inventory (BDI) scale to measure changes.
Our results revealed a significant reduction in depressive symptoms for those taking both magnesium and vitamin D, with 73.2% of them reaching a positive outcome score on the BDI. In contrast, the control group, which received only vitamin D, showed a less dramatic improvement, suggesting that the combined treatment may offer more benefits for those struggling with depression related to long-COVID.
While both groups experienced some improvement, our findings indicate that magnesium plus vitamin D supplementation presents a promising option for individuals coping with depression in the wake of COVID-19.

Calcitriol impacts depression positively
We explored how calcitriol, the active form of vitamin D3, impacts depression linked to neuroinflammation. Using a well-structured study with control and experimental groups, we examined the effects of calcitriol on mice exposed to lipopolysaccharide (LPS), a substance that induces depressive-like behavior and neuroinflammation.
During our experiments, we found that calcitriol not only reduced the inflammatory response in brain cells but also improved behavioral symptoms associated with depression. In particular, it lowered the levels of inflammation-related molecules while promoting anti-inflammatory ones in the brain's hippocampus, an area important for mood and memory.
We observed that calcitriol helped alleviate some of the negative behavioral effects triggered by LPS. The treatment also appeared to prevent the activation of microglia, the brain's immune cells, by interfering with a specific signaling pathway involved in inflammation.
Overall, our findings suggest that vitamin D3 could offer promising benefits as a treatment for depression by tackling neuroinflammation and protecting neuronal health.

We looked at how vitamin D3 could help combat depression, especially in the context of chronic stress. The study involved 40 male Wistar rats, divided into different groups to compare the effects of vitamin D3, the antidepressant fluoxetine, and a combination of both.
The rats underwent 21 days of mild but unpredictable stress, simulating conditions often linked to depression. To measure the effects, we conducted several behavioral tests and collected blood samples to assess hormonal changes.
Results showed that vitamin D3 had a positive impact similar to fluoxetine on the rats' depressive behaviors. Specifically, we found that vitamin D3 improved results in key behavioral tests, suggesting it can help protect against stress-induced anxiety and depression.
Notably, the levels of corticosterone, a stress hormone, were lower in rats that received vitamin D3, indicating a protective effect. Overall, this study emphasizes the potential of vitamin D3 in alleviating depressive symptoms resulting from chronic stress.

I struggle with getting enough sun exposure and was concerned about my vitamin D levels, so I started taking this supplement. It's fat-soluble, so I take one tablet post-dinner. I noticed I wake up feeling better rather than sluggish. Having dealt with depression for around a decade, I believe this has positively impacted my mental state, and I wish to keep taking it.

We explored the connection between 25-hydroxyvitamin D levels, physical activity, and the risk of developing depression in older adults. Using data from a large, longitudinal study called the English Longitudinal Study of Ageing, we focused on cognitively healthy individuals aged 50 and older.
Our findings showed that higher levels of 25(OH)D were associated with a significantly lower risk of depression. When we combined high levels of vitamin D with regular physical activity, the protective effect against depression was even greater, especially in those aged 65 and older.
Specifically, we noted that individuals with high levels of vitamin D and who engaged in physical activity had a 23.1% lower chance of developing depression. This combination not only highlights the importance of maintaining adequate vitamin D levels but also emphasizes incorporating physical activity into our daily routines as essential for mental health.
Ultimately, our results underscore the potential benefits of vitamin D supplementation and regular physical activity as strategies for preventing depression, particularly in older adults.

We explored how vitamin D supplementation might affect depressive symptoms and whether it has a dose-dependent relationship with these symptoms. By analyzing data from 31 randomized controlled trials involving nearly 24,200 participants, we aimed to clarify the potential benefits of vitamin D on depression. Our research revealed that, generally, increasing vitamin D intake appeared to lead to a slight reduction in depressive symptoms across different groups of individuals, whether they had a prior diagnosis of depression or not.
The effect was particularly significant for those already experiencing depressive symptoms, showing a marked improvement with higher dosages. Interestingly, we noted that the most substantial improvements occurred at a dosage of 8000 IU/day. Moreover, we found that shorter intervention periods of eight weeks or less, or those lasting between eight to 24 weeks, were associated with stronger positive effects than longer trials.
On the other hand, when it came to anxiety symptoms, vitamin D supplementation did not show a significant benefit. This suggests that while vitamin D might be a helpful tool for managing depression in the short term, we still need more high-quality trials to fully understand its impact on anxiety and to make a stronger case for its use in treating these symptoms.

We investigated whether vitamin D supplementation could help reduce depressive symptoms and lower the likelihood of needing antidepressants in older Australian adults. The D-Health Trial, which involved over 21,000 participants aged between 60 and 84, provided a solid platform for our research. This trial was carefully designed, using a randomized, double-blind, placebo-controlled approach, which is the gold standard in clinical research.
Participants answered the Patient Health Questionnaire (PHQ-9) to measure their depressive symptoms multiple times over five years, while national prescribing records allowed us to track the use of antidepressants.
Our findings revealed that monthly vitamin D supplementation did not show any significant benefits for alleviating depression overall. The average difference in PHQ-9 scores between the vitamin D and placebo groups was negligible. Moreover, the incidence of antidepressant use in both groups remained quite similar.
However, when we looked closer, some interesting trends emerged. For individuals already on antidepressants at the start of the study, vitamin D did seem to improve their depression scores slightly. Additionally, participants with low vitamin D levels at the outset showed a decrease in the risk of starting antidepressants after supplementation. Unfortunately, those with sufficient vitamin D levels saw an increased risk of antidepressant use.
Thus, while we didn’t find strong support for vitamin D's effectiveness against depression in general, our subgroup analyses suggest there might be some nuances worth exploring further.
