Children with low levels of vitamin D may be at higher risk of depression, the Daily Mail reported.
Scientists found that children with the highest levels of vitamin D had a 10 percent lower risk of developing depression, according to the UK website.
The study, conducted by researchers at the University of Bristol, examined vitamin D levels in more than 2,700 children at ages nine and 13.
The Daily Mail said those with the lowest levels of vitamin D were more likely to show warning signs of depression. Additionally, those with higher levels were more likely to show a decline in depressive symptoms during their teenage years.
Vitamin D is mainly produced by sunlight, though it is also found in oily fish like salmon and tuna. Of the two forms of the vitamin – D2 and D3 – the strongest protective link against depression was found in D3.
