Chronic Migraine linked with vitamin D deficiency.

New research shows that vitamin D deficiency is common in people suffering from chronic migraine. The observational study also showed that the longer the individual had chronic migraine, the more likely they were to be vitamin D deficient. While vitamin D deficiency is associated with a variety of diseases such as high blood pressure, Multiple Sclerosis, fibromyalgia, depression, and heart attack, it has not been associated with chronic migraine until now says Urbod Nutritionist Amanda Michie.
