If you have psoriasis, it is imperative that you have your vitamin D levels tested and maintain levels in the therapeutic range of 50-70 ng/ml year-round. Vitamin D is a potent immune modulator, making it very important for the prevention of autoimmune diseases.
According to one study, “vitamin D could have important immunomodulatory effects in psoriasis,” but unfortunately 80 percent of patients in winter, and 50 percent in the summer, were vitamin-D deficient.4
If you opt for a supplement, be sure to take vitamin D3—not synthetic D2—and take vitamin K2 and magnesium in conjunction with it. The biological role of vitamin K2 is to help move calcium into the proper areas in your body, and without sufficient amounts, calcium may build up in areas such as your arteries and soft tissues. This can cause calcification that can lead to hardening of your arteries—a side effect previously thought to be caused by vitamin D toxicity. We now know that inappropriate calcification is actually due more to lack of K2 than simply too much vitamin D.
Magnesium is also important, both for the proper function of calcium, and for the activity of vitamin D as it converts vitamin D into its active form. Magnesium also activates enzyme activity that helps your body use the vitamin D. In fact, all enzymes that metabolize vitamin D require magnesium to work. As with vitamin D and K2, magnesium deficiency is also common, and if you’re lacking in magnesium and take supplemental calcium, you may exacerbate the situation.
