Vitamin D Deficiency Linked To Schizophrenia

As evidence of the adverse health effects of vitamin D deficiency mounts, researchers in Iran have added a psychiatric impact. People who are vitamin D deficient are twice as likely to be diagnosed with schizophrenia as people with normal levels. The researchers analyzed findings of 19 observational studies on vitamin D and schizophrenia, finding that vitamin D deficiency is “quite common” among schizophrenics: people with low vitamin D were 2.16 times more likely to have schizophrenia than those with sufficient vitamin D. Sixty-five percent of study participants who had schizophrenia were also vitamin D deficient.
