One paragraph on Migraines caused by Vitamin Deficiencies

Whether it's stress or spending too much time focusing on computer/laptop screens we’re all susceptible to experiencing migraines and some people suffer from them even more than others; and we have heard many recommendations on how to prevent migraines, such as drinking plenty of water, but not the actual reasons why we get migraines. Researchers at Cincinnati Children's Hospital Medical Centre have found that a high percentage of children, teens and young adults with migraines appear to have mild deficiencies in vitamin D, riboflavin and coenzyme Q10. It’s possible that these deficiencies may play a role in the onset of migraines but this is still unclear, based on existing studies. In this study, the researchers’ trial drew from a database that looks at vitamin D, riboflavin and coenzyme Q10, all of which are all associated with migraines to some degree, and this has been reported in many previous research studies, some studies have even conflicted each other. Most of the study patients were put on preventative migraine medications and received vitamin supplements if their levels were low in the patient's bloodstream. Since a minority of the study population received vitamins alone, the researchers were unable to determine vitamin effectiveness in preventing migraines. Also, the researchers found that girls and young women were more likely than boys and young men to have coenzyme Q10 deficiencies at baseline. Boys and young men were more likely to have vitamin D deficiency but it’s unclear whether there were folate deficiencies. Patients with chronic migraines were more likely to have coenzyme Q10 and riboflavin deficiencies than those with episodic migraines. Many studies using vitamins to prevent migraines have been published but they have all had conflicting success, therefore more research, which doesn’t include the use of preventative migraine medications, is needed to determine the power that vitamins have on preventing migraines alone - and until research is no longer conflicting.

Why you can rarely get Vitamin D poisoning...

Vitamin D refers to a group of fat-soluble secosteroids (a subclass of steroids that consist of “broken” ring structures) that are responsible for the intestinal absorption of calcium, iron, magnesium, phosphate and zinc. The major natural source of the vitamin is in the skin. For vitamin D to be activated from cholesterol (via the skin) it requires sunlight to initiate the activation (especially UVB radiation); you can also obtain vitamin D from food, such as oily fish (salmon, sardines, cod liver oil etc...) and some fortified foods. Vitamin D has been shown to boost bone health and it may play a role in preventing diabetes, cancer, cardiovascular disease and other illnesses.

Vitamin D deficiency can occur if: the body has an increased need for vitamin D, the body is unable to produce enough vitamin D, or not enough vitamin D is being taken into the diet. Vitamin D deficiency is more common than vitamin D toxicity.

High doses of vitamin D...

A study conducted from 2002-2011, from patients in the Rochester Epidemiology Project, a National Institutes of Health-funded medical records pool that makes Olmsted County, Minnesota, USA, the home of Mayo clinic. Mayo Clinic is is one of the few places worldwide where scientist can share and study virtually an entire geographic population to identify health trends.

They found that an overdose of vitamin D was very unlikely to happen, even if levels raised more than 50 ng/mL; the given highest dose allowed in the blood in between 20-50ng/ml. The scientists took over 20,308 measurements, 8% of people had levels greater than 50 mg/mL and less than 1% of the people had levels of over 100 ng/mL.

"We found that even in those with high levels of vitamin D over 50 ng/mL, there was not an increased risk of hypercalcemia, or elevated serum calcium, with increasing levels of vitamin D," said study co-author Thomas D. Thacher, M.D., a family medicine expert at Mayo Clinic.

They also found that females over the age of 65 were more at risk of having very high vitamin D levels in their blood, which is expected since that group usually, takes vitamin D supplements.

Another notable outcome: The occurrence of high vitamin D levels over 50 ng/mL increased during the 10-year period of the study, from nine per 100,000 people at the start of the study up to 233 per 100,000 by the end.

"We were surprised by that degree of dramatic increase in vitamin D levels," Dr. Thacher said.

"Our bodies will naturally produce vitamin D when our skin is exposed to sunlight, however, we don't recommend excessive exposure to sun due to the risk of skin cancer," Dr. Thacher added.

Although, it has been recommended that doctors and GP’s always ask their patients whether they take vitamin D supplements, since some may consume capsules which contain 50,000 IU of vitamin D and if taken on a daily basis, it could lead to toxicity.

"The evidence is clear that vitamin D toxicity is one of the rarest medical conditions and is typically due to intentional or inadvertent intake of extremely high doses," wrote Hollick, a professor of medicine, physiology and biophysics at Boston University School of Medicine.
