What is Zinc Sulfate?
Zinc sulfate is an inorganic compound that comes in various hydrated forms, most commonly as a white, crystalline powder. It is usually synthesized by reacting zinc oxide with sulfuric acid.
Zinc sulfate is used primarily as a dietary supplement to provide adequate zinc intake, which is crucial for many biological functions such as immune response and cell division. In foods, it is often used to fortify products, particularly those intended for infants.
Seeing zinc sulfate on a label might indicate it is added to enrich zinc content; however, those with zinc allergies should be cautious.
