Vitamin D has been in the news quite a bit lately. Almost every magazine and every news channel had something to say about vitamin D. Most of the scientific reports are contradictory to each other about vitamin D and overall health. We certainly know one thing and that’s the sales of vitamin D supplements are sky rocketing.
Despite all that hype about vitamin D in news media, there is almost no information on vitamin D and its impact on psoriasis. As usual, we don’t have answers about how vitamin D supplements affect psoriasis. We know that Narrow Band UVB (NBUVB) treatments for psoriasis effectively increase serum vitamin D levels. Also, the same study from Ireland reported that up to 75% of Irish patients with psoriasis had low levels of serum vitamin D during winter time.
On the other hand, topical vitamin D treatment for psoriasis has been around for a long time. Topical vitamin D has been shown to be beneficial in alleviating psoriasis plaques. Topical vitamin D is also known to work with topical steroids together. Also, long term topical vitamin D treatment is useful without the long term side effects of topical steroids.
Lately, we are also finding that topical vitamin D maybe helpful in preventing psoriatic lesions. Of course, this will require further research to be confirmed scientifically.
