We explored the effect of vitamin D3 supplementation on anxiety levels among elderly individuals diagnosed with prediabetes. In our study, we randomly assigned participants to receive either a weekly dose of 25,000 IU of vitamin D3 or a placebo, alongside general lifestyle recommendations. Over the course of 12 months, we measured anxiety levels using standardized assessments.
At both the six-month and twelve-month marks, the participants receiving vitamin D3 reported significantly lower anxiety levels compared to those who did not receive the supplementation. Specifically, scores measuring anxiety decreased from 38.02 to 32.35 in the vitamin D group, while control participants’ scores remained much higher throughout the study.
These results indicate that vitamin D3 could be a beneficial and safe option for alleviating anxiety in an older population already facing the challenges of prediabetes. The participants who had vitamin D deficiency or insufficiency at the start of the study experienced similar improvements, emphasizing the treatment's potential across various baseline vitamin D levels.
Overall, our findings support the idea that vitamin D supplementation can effectively help mitigate anxiety symptoms in older adults, and we believe further research is warranted to better understand the mechanisms at play.

We explored how coal dust exposure leads to anxiety and depression-like behaviors in mice, using a pneumoconiosis model that was established after 28 days of exposure. This model allows us to closely observe the effects of environmental factors on mental health. Through treating the mice with Vitamin D3 for three months, we aimed to see if this treatment could alleviate anxiety symptoms.
Our findings were quite revealing. Vitamin D3 treatment showed a significant positive effect; it reduced signs of anxiety and depression. Specifically, we saw improvements in tests designed to measure these behaviors, along with a decrease in markers of astrocyte activation—cells in the brain that can become overactive in stressful situations. Vitamin D3 also promoted better neuron protection and enhanced the distribution of brain-derived neurotrophic factor (BDNF), a crucial element for brain health.
This study suggests that Vitamin D might serve as a useful approach for managing mood disorders resulting from environmental stressors such as coal dust. These findings also highlight the importance of further exploring Vitamin D3 as a potential treatment avenue for anxiety exacerbated by particulate matter exposure.

We examined the effects of vitamin D3 on anxiety in mice experiencing nicotine withdrawal. To conduct our research, we divided male C57/BL6 mice into four distinct groups: those receiving a vehicle, those receiving nicotine alone, those receiving vitamin D3 alone, and those receiving both nicotine and vitamin D3.
During the six-week study, the mice were given nicotine through their drinking water and vitamin D3 in their feed. When the withdrawal phase kicked in, we observed that mice treated with vitamin D3 demonstrated significantly reduced anxiety-like behaviors. This was measured using open-field tests and marble burying tests, where these mice spent more time in the central area and buried fewer marbles compared to those that did not receive vitamin D3.
Additionally, our study revealed that vitamin D3 supplementation reduced hippocampal NR2A expression, which may be linked to lowering anxiety during nicotine withdrawal. These findings suggest that vitamin D3 supplementation could be a promising dietary intervention for people dealing with anxiety related to quitting smoking.

We explored the effects of vitamin D3 on anxiety levels in rats subjected to chronic unpredictable mild stress. In our study, we used a total of 40 male Wistar rats, dividing them into five groups to analyze various treatments. These groups included a control group, a stress group, and groups receiving either vitamin D3, fluoxetine (an antidepressant), or a combination of both.
The chronic mild stress model we applied involved exposing the rats to different physical and social stressors over 21 days. Throughout the study, we monitored changes in behavior through established tests, such as the sucrose preference test and the forced swimming test, while also measuring stress hormone levels.
Our findings revealed that vitamin D3 had a protective effect against anxiety and depressive behaviors similar to fluoxetine, particularly in certain behavioral tests. In groups receiving vitamin D3, we observed lower levels of stress hormone corticosterone compared to those only exposed to stress.
Overall, we concluded that vitamin D3 can offer significant support against anxiety when faced with stress. While it was effective, we noted that the combination with fluoxetine complicates isolating the specific impact of vitamin D3 alone.

High-dose vitamin D reduces anxiety
We conducted a study to understand how high-dose vitamin D supplementation might impact anxiety levels, particularly in patients experiencing post-COVID symptoms. In our double-blind, randomized controlled trial, we enrolled 80 individuals dealing with fatigue or neuropsychiatric issues after COVID-19.
Participants were split into two groups: one received a weekly dose of 60,000 IU of vitamin D, while the other group received a placebo. Over eight weeks, we evaluated various outcomes, including anxiety levels using the Depression, Anxiety, and Stress Scale (DASS-21).
The results were encouraging for the vitamin D group. We observed significant improvements in anxiety levels, with a notable reduction reported by participants. However, other measures related to sleep quality, depression, cognitive function, and inflammatory markers did not show similar significant changes.
Importantly, we found that the vitamin D group reported no serious adverse effects, indicating that this supplementation is generally safe. These findings suggest that high-dose vitamin D may offer substantial benefits for anxiety relief in patients recovering from COVID-19, albeit with limited effects on other symptoms.
