Does Vitamin D affect depression in adults?

A/Prof Andre Renzaho has co authored a study which looks at using Vitamin D to reduce depression in adults

According to the study, its objective is to estimate the effect of vitamin D supplementation in reducing depressive symptoms among the adults aged 18 years or older diagnosed with depression or depressive symptoms.

Nine trials with a total of 4923 participants were included in the analysis. There was no significant reduction in depression following vitamin D supplementation, however, most of the studies focused on individuals who had low level of depression and sufficient serum vitamin D at baseline. The included studies used different vitamin D dose with a varying degree of intervention duration.
The study notes that future randomised controlled trials examining the effect of vitamin D supplementation among individuals who are both depressed and vitamin D deficient are needed.
