This review aims to investigate the influence vitamin D has on the severity of depressive symptoms in children and adolescents. Current studies have shown the potential role of vitamin D on mental health in adults, but results have been inconclusive among children. Using PubMed, Scopus, and CINAHL Complete, studies were selected by searching the terms “Vitamin D, depression, children and adolescents.” The inclusion criteria consisted of data over the last five years, presenting vitamin D intake or status in subjects between the ages of 2-17, and a diagnosis of depression. Eleven studies met the eligibility criteria. Nine of the studies demonstrated that adequate levels of Vitamin D3 provide positive outcomes in terms of depression symptoms. One study failed to show the effect of self-rated depression in adolescents, but parents reported fewer depressive symptoms. Another study showed that Vitamin D status did not seem to be associated with depression symptoms among adolescents. Overall, the results demonstrate a positive effect of oral supplementation suggesting a need for increased intake of Vitamin D3 for individuals suffering from depression.
