Zinc supports the immune system. Psoriasis is the opposite of an immune deficiency. It is caused by a ramped up immune system (you also have to have the genetic factor for it). I will take 50 mg of zinc while I am healing, but then will just take my multi, which has much less zinc. By the way, chewable vitamins for adults rock! The chocolate chewable calcium is almost too good! The liquid multi makes me gag, but I will finish the bottle because I am cheap!
