Vitamin D helps reduce migraines
Vitamin D supplementation for the treatment of migraine: A meta-analysis of randomized controlled studies.
Study highly relevant to migraine
We explored the potential benefits of vitamin D supplementation for treating migraines. Our analysis focused on several randomized controlled trials (RCTs) to examine how effective vitamin D could be in alleviating migraine symptoms.

Through our review, we included six RCTs involving 301 patients. The results were quite promising. Vitamin D supplementation significantly reduced the number of headache attacks per month and the number of headache days experienced by patients. Additionally, it improved the MIDAS score, which measures the impact of migraines on daily life.

However, it's important to note that vitamin D did not show a significant effect on how long migraine attacks lasted or the severity of the headaches. Overall, our findings suggest that while vitamin D might be beneficial for reducing certain migraine-related symptoms, it isn’t a miracle cure for everyone.

Vitamin D linked to lower migraines
Higher Circulating Vitamin D Levels Are Associated With Decreased Migraine Risk: A Mendelian Randomization Study.
Direct focus on vitamin D effects
We investigated how vitamin D levels in the body are related to the risk of experiencing migraines. Using a method called Mendelian randomization, we carefully examined data from a large group of over 400,000 individuals to identify genetic factors linked to vitamin D levels. We found a total of 184 genetic instruments to analyze the potential relationship.

The findings were intriguing: as vitamin D levels increase, the risk of migraines appears to decrease. This association was confirmed through multiple datasets, showing that higher vitamin D is associated with a reduced likelihood of having migraines. The results were consistent not just for general migraine types but also for specific subtypes, such as migraines with and without aura.

Interestingly, while we checked for potential mediators like serum calcium, the contribution of calcium to this relationship was minimal. Our research suggests that low vitamin D levels could be a concern for migraine sufferers, and it highlighted the need for further well-designed studies. We recommend that future research explore the effects of vitamin D supplementation, especially for those who may be deficient in this important nutrient.

Vitamin D3 may aid migraine treatment
The effects of vitamin D3 supplementation on TGF-β and IL-17 serum levels in migraineurs: post hoc analysis of a randomized clinical trial.
Focus on vitamin D's impact
We conducted a placebo-controlled trial to examine how daily supplementation of 2000 IU of vitamin D3 affects immune markers related to migraine. Over 12 weeks, we enrolled eighty episodic migraineurs, dividing them into two groups: one received vitamin D3, while the other received a placebo.

At the end of the trial, we found that vitamin D3 had a notable influence on certain immune indicators. Specifically, the serum levels of transforming growth factor-beta (TGF-β) were significantly higher in the vitamin D group compared to the placebo group. This suggests that vitamin D3 might enhance the balance of cytokines associated with immune response in those suffering from migraines.

On the flip side, vitamin D supplementation also appeared to prevent an increase in interleukin-17 (IL-17) levels, another immune marker linked to inflammation. Interestingly, we noted a positive correlation between changes in vitamin D levels and TGF-β, suggesting a beneficial connection. However, no such correlation was observed for IL-17.

These findings highlight the potential role of vitamin D3 in modulating immune responses in migraine patients, but further research is necessary to confirm these effects.

Remarkable migraine improvement
I have had migraines for over twenty years, and after trying Vitamin D on a whim, I have not experienced a migraine in two months. This is unprecedented for me. I take 1,000 IU in the morning and another in the evening, and it has been life-changing. I encourage others to consult their doctor for the right dosage.

Vitamin D may alleviate migraines
The association of serum vitamin D concentrations in paediatric migraine.
Focuses on pediatric vitamin D impacts.
We aimed to understand how vitamin D impacts migraine headaches in children. Through a thorough review of existing literature, we explored the significant association between serum vitamin D levels and the frequency and duration of migraine episodes in the pediatric population.

Our findings suggest that children with migraines might benefit from vitamin D supplementation. By potentially reducing the number and intensity of migraine episodes, vitamin D could improve the overall quality of life for these young patients.

It's important to note that this connection primarily focuses on children, as most studies have looked at adults. With vitamin D deficiency being a growing public health concern, our research highlights how addressing this deficiency may serve as a helpful strategy in managing pediatric migraines.

Pediatric migraines and vitamin D
The Impact of Vitamin D Supplementation to Topiramate Therapy on Pediatric Migraine Prophylaxis.
Study on vitamin D's role
We conducted a study to investigate whether adding vitamin D supplements to topiramate therapy would improve migraine outcomes in children aged 5 to 14. In our double-blinded clinical trial, we randomly assigned participants to receive either topiramate with a daily 5000-IU vitamin D supplement or topiramate with a placebo for four months. By evaluating changes in headache frequency, severity, disability, and overall response to treatment, we aimed to see if vitamin D could provide additional benefits.

Our findings were quite promising. The children receiving the vitamin D supplement had a significant reduction in the number of headaches they experienced each month compared to those on placebo. Additionally, the vitamin D group reported less disability due to migraines and a higher percentage of positive treatment responses. Specifically, about 76% of children in the vitamin D group showed a good response, compared to just over 53% in the placebo group.

Safety was assessed as well, with side effects occurring in 13.3% of the vitamin D group and 20% in the placebo group, indicating that vitamin D was well-tolerated. Overall, we believe that combining vitamin D with topiramate represents a safe and potentially effective approach to managing pediatric migraines.

Vitamin D and probiotics benefit migraines
Effects of probiotic and vitamin D co-supplementation on clinical symptoms, mental health, and inflammation in adult patients with migraine headache: a randomized, triple-blinded, placebo-controlled trial.
Study shows significant potential
We conducted a rigorous study to understand how vitamin D, combined with probiotics, can affect migraine headaches. In a randomized, triple-blinded, placebo-controlled trial, we enrolled adult patients aged 18 to 55 diagnosed with migraines. These individuals were divided into two groups: one receiving vitamin D and probiotics and the other receiving a placebo for 12 weeks.

Throughout the study, we assessed various factors, including the frequency and severity of migraines, mental health outcomes, and inflammation levels. Participants completed questionnaires and maintained a daily headache diary to track their symptoms.

After 12 weeks, we observed that the combination of vitamin D and probiotics had positive effects on the characteristics of migraines. However, while there were improvements noted, further research is needed to fully confirm these results. It's important to consider that we cannot isolate the effect of vitamin D alone due to its combination with probiotics in this study.
