well, the evidence is mixed. and, in any case, the two studies mentioned in this 'news' story are over 12 years old.

the error bar says

for some unknowable reason, this week, the Express reports two old studies examining links between vitamin D and depression.

they report a 2008 study on overweight and obese people, and a 2006 study on fibromyalgia – two completely different studies – in which both mentioned depression. in these studies, vitamin D supplements were said to reduce the symptoms of depression.

does vitamin d cure depression?

now clearly this is an important topic – but why drag up these old articles now? if they had looked a little harder, as the error bar has done, they could have found at least 6 systematic reviews and/or meta-analyses of the effects of vitamin D on depression published since 2013. three of these studies concluded there was no effect, and three that there was a benefit of vitamin D on depression.
