Theres no suc thing as a dermatology degree. Thats not how becoming a doctor works which leads me to believe you are not a doctor and just want to stroke your ego by giving out potentially harmful medical advice On the fallacious grounds of an appeal to authority. Zinc competes with copper. Copper deficiency LEADS to iron anemia. Supplementing iron On top of high dose zinc will only serve to make youy more toxic and constipated. Also, when you take supplements you have to consider how much of that particular nutrient youre getting from your regular diet. For most people taking over 25mg/day is poisonous. If yoy like zinc forcolds, consider using Zicam as directed. Works for me.
