New research published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism, has found that people who suffer from a vitamin D deficiency, are twice as likely to be diagnosed with schizophrenia.

Scientists found that 65% of participants who were schizophrenic, were also deficient in Vitamin D.

Schizophrenia is more common in countries with cold climates, as the skin produces Vitamin D after exposure to sunlight.

Dr Ahmad Esmaillzadeh, one of the research authors said: “Our findings support the theory that vitamin D may have a significant impact on psychiatric health. More research is needed to determine how the growing problem of vitamin D deficiency may be affecting our overall health.”

You can get your vitamin D from exposure to sunlight, supplements and foods such as cod liver oil, fish and eggs.
