Maintaining a balanced level of Vitamin D has been associated with alleviating the effects psoriasis.  This is especially true for people who are vitamin D deficient.  Vitamin D promotes quick healing in the skin, strong bones and helps promote effective mineral absorption in the body.

The effects of balanced levels of vitamin D seems to be related to the generally positive effect that sunlight has on psoriasis.  Exposing your skin to some sunlight every once in a while allows your skin to produce pretty much all the vitamin D that your body needs.

So, while it is probably true that sunlight specifically helps to fight back psoriasis, it is probably also the case (maybe even more so) that sunlight is necessary for everyone (psoriatic or not) to have an all around healthy life.  Having a balanced, healthy life — including exercising, going outside, sleeping and eating healthy natural food — promotes maximum health.  These things also happen to be labeled natural “remedies” for psoriasis.  When you string them all together, it no longer seems appropriate to call them “remedies” — “things we should be doing to stay healthy” might be a better label.

Definitely be cautious about taking vitamin D as a supplement, however, since taking too much will throw off the balance of minerals in your system (calcium and iron in particular) and thus cause a general ruckus in your bodily systems.  But this shouldn’t surprise you since taking too much of pretty much anything will throw off your physical health.  If you must take vitamin D supplements, a doctor will be able to tell you how much you should take as well as with what other supplements (it is not recommended that anyone take vitamin D by itself).
