One of the problems with psoriasis is that it seems to behave differently for different people and also changes over time too which makes it very much a case of trial and error to find what treatments work for people.
There's definitely a link between psoriasis and vitamin D, but as you state, it's not necessarily a deficiency that triggers it. However, anecdotally there's people who do benefit from taking vitamin D3 (along with K2 seems to be a popular combo) so I think it's worth a shot though I have tried it in the past without much success (that wasn't erythrodermic psoriasis though).
I've definitely noticed that sun exposure does help with plaque psoriasis and most people will see that their condition worsens over winter - that may be due to lower sunlight levels or cold, dry air exacerbating skin issues. And yes, psoriasis does affect people's self-image, so it can be embarrassing to expose skin when it looks like you've got some kind of plague.
- atombender 3y agoTrue, and I would never go as far as saying that the benefits have been disproven. I do hear about many people trying to treat their psoriasis wit vitamin D, but not about many success stories. As far as we know, the reason sunlight helps psoriasis is not vitamin D, but because UVB at specific wavelengths has an immunosuppressive effect on the skin. It induces apoptosis of T-cells and promotes keratinocyte differentiation.

It seems to my non-expert opinion that it's a piece of the puzzle, but there's a lot more other pieces. It seems to be often linked with selenium deficiency and I've read one case of a really bad erythrodermic patient that was treated with calcium.
