Vitamin D Deficiency and Frequent Headaches
A new study looked at 2600 Finnish men, aged 42-60 years, who were participating in the population-based Kuopio Ischemic Heart Disease Risk Factor Study (KIHD), based in eastern Finland. Since this study was already monitoring their vitamin D levels, some researchers decided to see if there was a link between frequent headaches and vitamin D deficiency.
Indeed, those men who had the lowest serum levels of vitamin D were much more likely to suffer from frequent headaches in comparison to those with the highest circulating vitamin D levels.
“After adjusting for age and year and month of blood draw, patients with recurring headaches had an average serum 25(OH)D concentration of was 38.3 nmol/L, while patients no headache complaints had an average of 43.9 nmol/L.”
When we convert this 43.9 nmol/L measurement to the more frequently referenced ng/ml, the result is 17.56 ng/ml, and most experts on vitamin D suggest that we ideally have levels between 40 and 60 ng/ml. So, based on current research (available in our free Vitamin D – E book), even those in this study who had optimal levels of vitamin D for preventing headaches, were still low by the standards of vitamin D experts.
