I am tired of people posting ONE study and think it discredits the plethora of other studies on zinc and the immune system. I can say several things about that zinc study; it was give too late, it was not mucosal, it was performed in non-hospitalized patients. All these patients might have been fine with Zinc but low in selenium of vitamin D. But you will not listen. I can ask you, is a zinc deficiency good or bad for balanced immunity?
