 A new meta-analysis of the relationship between vitamin D levels and schizophrenia shows that people with this disease, characterized by hallucinations and delusions, have significantly lower levels of vitamin D in their blood than do controls. The research, led by Dr. Ahmad Esmaillzadeh of the Isfahan University of Medical Sciences in Iran, reviewed 19 studies of the link between vitamin D and schizophrenia in almost 3,000 adults. Sixty-five percent of the participants with schizophrenia were vitamin D-deficient. |
