10 Side Effects of Zinc
Zinc Side Effect #1: Stomach Problems
Even those of us with resilient stomachs can encounter some substances that irritate us. This can lead to pain, diarrhea and other unpleasant symptoms. It is usually quite easy for us to identify and avoid such substances, but we will sometimes consume an irritant unknowingly.
Zinc can be irritating to the stomachs of some people. This can lead to considerable pain, diarrhea and other symptoms such as vomiting and nausea. Strong concentrations of zinc are even known to be corrosive to the digestive system, potentially causing considerable damage. There have also been reports of excess zinc causing intestinal bleeding, so it is wise to use it with caution.
