Could the winter blues be a myth?
A lack of vitamin D caused by reduced sunlight has long been believed to cause Seasonal Affective Disorder.
But researchers at Warwick Medical School found no clear link between low levels of vitamin D in the blood and depression after testing more than 3,200 in China.
Dr Oscar Franco, who led the research, said: "More studies are still needed to evaluate whether vitamin D is associated with Seasonal Affective Disorders, but our study does raise questions about the effects of taking more vitamin D to combat depressive symptoms."
The study is published in the Journal of Affective Disorders.
