Can vitamin D deficiency cause migraines?
If you suffer from migraines, it might be due to a deficiency in Vitamin D according to new research.
Researchers from Cincinnati Children’s Hospital Medical Centre measured the blood Vitamin D levels (an some other vitamins) of young patients with migraines. They found a high percentage of individuals tested showed deficiencies in Vitamin D.
While more research is needed to further validate this, and a widespread study would be needed to demonstrate whether regular Vitamin D supplementation could prevent migraines, it is certainly welcome news to individuals prone to migraines. According to The Migraine Trust, 3,000 migraine attacks occur every day for each million of the general population. That equates to over 190,000 migraine attacks every day in the UK alone!
The link between vitamin D and migraines
Researchers from Cincinnati Children’s Hospital Medical Centre recently examined blood Vitamin D levels (as well as other vitamins) in a group of young patients experiencing migraines. The findings were eye-opening: a large percentage of these individuals showed significant Vitamin D deficiencies.
Vitamin D plays an essential role in many body systems, including nerve health, inflammation control, and hormone balance—all of which can influence migraine activity. Low levels of Vitamin D may make the nervous system more sensitive to pain or trigger inflammation pathways that contribute to the onset of headaches.
Although more studies are needed to confirm the connection, early evidence supports the idea that maintaining healthy Vitamin D levels could help reduce the frequency and intensity of migraines.
The scale of the problem
According to The Migraine Trust, approximately 3,000 migraine attacks occur every day for every one million people in the general population. That adds up to more than 190,000 migraine attacks every single day in the UK alone. For many, migraines are not just painful—they are debilitating, affecting work, mood, and quality of life.
If even a portion of these cases could be linked to a correctable nutrient deficiency, improving Vitamin D intake might represent a simple, low-cost step toward better health and fewer migraine days.
How to support healthy vitamin D levels
While you can obtain Vitamin D from sunlight exposure, modern lifestyles, sunscreen use, and long winter months often mean that many people—especially those in northern climates—don’t get enough. That’s why Vitamin D supplementation has become increasingly popular among individuals looking to support immune function, bone health, and now, possibly, migraine prevention.
At Vegetology, we offer Vit-D3 Vegan Vitamin D3 in different dosages, making it easy to tailor your intake to your needs. For individuals prone to migraines, we recommend starting with our 1000 IU Vitamin D3 spray.
Each 5-pump dose provides the full 1000 IU daily amount. After 4–6 weeks, you can reduce your intake to a maintenance level of 200–400 IU per day (depending on your region’s recommended Vitamin D3 dose).
As always, please consult your doctor before starting any supplement, especially if you have existing health conditions or are taking other medications.
Key takeaway
While more research is needed to fully establish the role of Vitamin D in migraine prevention, the current findings are promising. For migraine sufferers, checking your Vitamin D levels and ensuring you’re not deficient could be a simple yet powerful step toward better headache management and overall wellness.
