There is pretty strong evidence of a link between vitamin D levels and depression i.e. more vitamin D reduces depression.

I wonder if that is independent of sunshine - see SAD (Seasonal affective disorder) - and Vitamin D supplements would help. The one report of a study which I looked at when I Googled "vitamin D and depression" didn't specify. "more studies needed".
