Oh thank goodness you clarified Zinc deficiency encourages Pseudo. I really did not understand what binding to actually meant on a practical level. It correlates with my experience. Often times I feel better after taking Zinc. My pulmo mentioned about iron also. But it is a bit confusing since he made it sound like it could be an issue taking iron or getting an iron infusion if you have Pseudo. But he did say if you really need it, take it.
