Low levels of vitamin d more common in people with mood disorders than schizophrenia

People with mood disorders are more likely to have low levels of vitamin D than those with schizophrenia, French research shows. Low vitamin D has been significantly linked to schizophrenia. A 2014 review of 19 studies, which included more than 2800 participants, showed that those with vitamin D deficiency were more than twice as likely to be diagnosed with schizophrenia compared with their counterparts who were not vitamin D deficient. But there have been conflicting results from previous studies on the relationship between vitamin D levels and mood disorders, especially major depression.
