Our findings highlighted a significant increase in anxiety-related behaviors, which we measured through various tests like the open field and elevated plus maze assessments. Interestingly, we observed that supplementing with vitamin D3 led to noticeable improvements in these anxiety behaviors, suggesting a protective role for vitamin D3 against the adverse effects caused by altered hormone levels from the Cyp11a1 overexpression.
Additionally, we found that vitamin D3 treatment not only helped in behavioral aspects but also corrected underlying neuroinflammatory responses—specifically the activation of microglia in the brain. This suggests that addressing vitamin D levels during pregnancy could be a potential strategy to mitigate these changes and improve outcomes for offspring at risk of autism spectrum disorders.
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.
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.

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.
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.

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.

Frequently Asked Questions
Anxiety is a natural and often healthy emotion characterized by feelings of worry, nervousness, or fear about an impending event or situation. While some level of anxiety is a normal reaction to stress, excessive or chronic anxiety can become a mental health issue. It may present in various forms, from everyday worries to more severe conditions such as generalized anxiety disorder (GAD), panic disorder, or social anxiety disorder. Symptoms can manifest both psychologically, such as persistent worry and difficulty concentrating, and physically, including symptoms like increased heart rate, sweating, or fatigue.
Understanding the difference between normal anxiety and an anxiety disorder is crucial. Normal anxiety can be beneficial, motivating you to prepare for important events like exams or public speaking. However, when it starts to interfere with daily activities or leads to avoidance behaviors, it may indicate the need for professional help. Treatments for anxiety often include therapy, medications, and lifestyle changes, allowing individuals to manage their symptoms effectively. If someone is struggling with anxiety that impacts their quality of life, seeking guidance from a healthcare professional is a key step toward recovery.
Vitamin D is a fat-soluble vitamin that's essential for maintaining healthy bones and teeth, supporting immune system function, and facilitating normal cell growth and development. It plays a crucial role in calcium absorption in the gut, which is vital for bone health. Unlike most vitamins, our bodies can produce Vitamin D when exposed to sunlight, specifically UVB rays, which is why it’s often referred to as the "sunshine vitamin." However, depending on your geographical location, lifestyle, and skin type, getting sufficient Vitamin D from the sun alone can be challenging, particularly during the winter months.
In addition to sunlight, Vitamin D can be obtained from certain foods such as fatty fish (like salmon and mackerel), fish liver oils, and fortified foods like milk and cereals. Some individuals may also consider supplements, especially if they're at risk for deficiency. Insufficient vitamin D levels are linked to various health issues, including rickets in children, osteomalacia in adults, and even an increased risk of chronic diseases. Regularly checking your vitamin D levels and consulting with a healthcare professional can help ensure you're meeting your needs for optimal health.
While the relationship between Vitamin D and anxiety is still being studied, there is some evidence to suggest that adequate levels of Vitamin D may play a role in mental health. Vitamin D is essential for overall health, including the functioning of the brain. Some studies have indicated that low levels of Vitamin D may be linked to increased anxiety and depression, although it's important to note that the exact mechanisms are not fully understood and more research is needed to draw definitive conclusions.
Moreover, sunlight is a natural source of Vitamin D, and regular exposure to sunlight can improve mood and help alleviate feelings of anxiety. However, it’s crucial to consult with a healthcare provider before making any significant changes to your supplement routine, especially if you are experiencing anxiety. They can help determine if a Vitamin D deficiency is a concern for you and whether supplementation might be beneficial. Overall, while Vitamin D could potentially support mental health, it is only one piece of a comprehensive approach to managing anxiety.
Based on user reviews, many individuals report noticeable improvements in their anxiety symptoms after consistently taking this supplement. A significant number of users highlight that they began to feel the effects within a month of starting the regimen. For example, one user mentions, "After using this product for a month, I am impressed with the results," indicating a positive change pertaining to anxiety at that time (Read Review). Another user notes a marked reduction in anxiety levels after approximately the same duration of use, sharing a life-changing experience after just a few days (Read Review).
Moreover, some reviews suggest that the results may vary, but a minimum of a month seems to be a common timeframe for users to start feeling relief from anxiety. Many testify to enhanced energy, mood improvement, and a general alleviation of anxiety symptoms within this window, implying that continued use beyond the initial period may yield even more significant benefits (Read Review). Therefore, while individual experiences may vary, a month is a typical benchmark cited by users for observing initial positive effects on anxiety.
Scientific research supports the potential of vitamin D as a supplement for alleviating anxiety. A study indicated that high-dose vitamin D supplementation significantly reduced anxiety levels in participants recovering from COVID-19, suggesting its effectiveness in this unique context [1]. Additionally, a broader investigation among U.S. adults found that higher serum vitamin D levels were inversely associated with anxiety risk, further underscoring the possible protective effects of vitamin D against anxiety disorders [4].
Moreover, specific subgroups, such as those suffering from type 2 diabetes or elderly individuals, have shown notable improvements in anxiety symptoms with vitamin D supplementation [24], [15]. However, while vitamin D appears to be associated with anxiety relief, the nuances of individual responses — such as those related to genetic factors and hormonal status — suggest that further research is warranted to fully understand its role in anxiety management. Overall, existing evidence points towards vitamin D supplementation as a potentially beneficial avenue for reducing anxiety, particularly for specific populations.
Based on user reviews, many individuals have reported significant improvements in their anxiety symptoms after incorporating this vitamin into their daily regimen. Users frequently mention reductions in feelings of anxiety and an overall enhancement in mood and energy levels. For example, one user shared, "I used to frequently suffer from anxiety and depression, but since using this supplement, those symptoms have vanished" (Read Review). Another noted a substantial decrease in anxiety, indicating a positive transformation after just a few days of use, saying, "my anxiety has decreased by about two-thirds" (Read Review).
Many users report that these improvements often occur within one month of starting the supplement, as highlighted by reviewers who have experienced enhancements in energy and stress relief alongside reductions in anxiety (Read Review). It's also common to hear anecdotes of improved sleep quality, with users attributing their newfound restful nights to the effects of the vitamin (Read Review). However, individual results can vary, and while many have reported substantial benefits, some users did not experience the same level of improvement (Read Review). Overall, the consensus among reviewers suggests that this vitamin could be a valuable addition to one’s health routine for alleviating anxiety-related symptoms.
Based on user reviews, many individuals have reported positive experiences when combining this vitamin with other supplements to manage anxiety. Notably, one user mentioned that after taking this vitamin alongside MagneB6 for a month, they experienced a marked improvement in mood, with a significant reduction in symptoms of apathy and anxiety (Read Review). Another user found that the combination of vitamin D with magnesium and zinc helped diminish their anxiety around sleep, highlighting the benefits of these minerals in conjunction with vitamin D (Read Review).
Several reviewers praise the effects of this vitamin on overall well-being, especially when included in a broader supplement routine. For instance, one user shared how they experienced an uplift in mood and a decrease in anxiety when using the vitamin alongside other health-conscious choices (Read Review). However, as with all supplements, individual outcomes vary, and some users noted negative side effects when combined with other products, emphasizing the importance of adjusting dosages and combinations based on personal reactions (Read Review). This highlights that while combining supplements can yield substantial benefits for anxiety relief, monitoring effects carefully and consulting with a healthcare provider can help optimize results.
Based on research findings, the optimal dose of Vitamin D for treating anxiety varies depending on the specific context and population studied. For instance, a study on post-COVID patients indicated that a high weekly dose of 60,000 IU of vitamin D resulted in significant improvements in anxiety levels over an eight-week period [1]. This suggests that higher doses could be effective, particularly in individuals experiencing anxiety as a result of health challenges like COVID-19.
Moreover, another study involving elderly individuals diagnosed with prediabetes utilized a weekly dose of 25,000 IU of Vitamin D3, resulting in notable reductions in anxiety scores after 12 months [15]. These examples highlight that higher doses—whether 60,000 IU for specific post-COVID symptoms or 25,000 IU for elderly individuals—can provide substantial benefits. However, the overall relationship between Vitamin D levels and anxiety emphasizes the need for targeted and possibly personalized supplementation strategies, particularly considering individual health conditions and deficiencies.
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.
Our analyses revealed that higher levels of serum vitamin D were associated with a lower risk of experiencing anxiety. Specifically, we found a significant inverse relationship; as vitamin D levels increased, the likelihood of anxiety decreased. This connection remained strong even after adjusting for various factors that could influence the results.
Furthermore, smooth curve fitting techniques confirmed a negative association between vitamin D and anxiety risk. Nonetheless, while these findings are promising, we emphasize the need for further prospective studies to validate these results and fully understand the implications of vitamin D on mental health.
At the end of the study, we noticed some significant changes among the women who received vitamin D3. Their anxiety scores dropped markedly compared to the placebo group, which indicates a positive impact on their mental well-being. Additionally, there was a notable reduction in markers of inflammation, while other mood indicators, such as depression, improved as well.
Our findings suggest that vitamin D3 supplementation might be a valuable tool in improving mood and reducing anxiety for women with diabetes who are also facing vitamin D deficiency. This combination of physical health and mental well-being is crucial, especially for managing diabetes more effectively.
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.
