Lamdage,
Thank you for your reply. I think that given the evidence implicating low vitamin D levels in a range of health problems that supplementing with the vitamin-hormone would be a good idea for individuals with a vitamin D deficiency or insufficiency, especially for those who aren't likely to enough vitamin D from the sun. Having said that, I think that the idea that low vitamin D levels are likely a consequence of depression, as opposed to a cause of depression, has some merit. The abstract of the study that I mentioned in my original post did seem to indicate that the study's findings were preliminary, judging from the fact that it was stated in the conclusions that large randomized controlled trials are needed to either definitively support or definitively refute the idea that low vitamin D levels can be a cause of depression. So, despite what the headline of the news article I linked to said, I don't think that the study that I mentioned "debunked" anything as much as it provided some evidence to support the idea that low vitamin D levels are likely a consequence of depression and not a cause. As far as I can tell, more evidence is needed before one can conclusively say that low vitamin D levels either do or don't cause depression.
I will say that judging from my own experimentation with vitamin D3 supplementation that I think that low vitamin D levels will ultimately turn out not to be a cause of depression. Despite experiencing what seemed to be a strong response to the vitamin-hormone at times during my trial, I ultimately didn't seem to respond in the long run. Of course, I'm just making a prediction based on my own experience with taking vitamin D3 supplements for depressive symptoms and to correct a vitamin D insufficiency, and I know that my own experiences don't make for the best of evidence, but that's what I'm predicting (that the evidence will eventually support the idea that low vitamin D levels aren't a cause of depression). Still, as I said earlier, I do think that supplementing to correct a vitamin D deficiency or insufficiency is a good idea, as I continue to take vitamin D3.
