Xinc in PreserVision

Hello,

I've never used PreserVision but I doubt that zinc would cause IBS symptoms.  Zinc is an important mineral to the body and needed to run certain metabolic pathways.  Excessive amounts of zinc can cause nervous system damage but that would be a lot.  I don't think you have anything to worry about but if you're still worried then maybe you should consult with your doctor to make sure.
