What it is

Zinc sulfate is a mineral salt that contains zinc and sulfate. It is typically produced industrially by reacting zinc or zinc oxide with sulfuric acid. It appears as a white crystalline powder or colorless crystals.

Why it's used

Zinc sulfate is added to foods as a source of the essential mineral zinc, which is important for immune function and cell growth. It is often found in fortified beverages, nutritional supplements, and some processed foods.

Health notes

In the U.S., zinc sulfate is generally recognized as safe (GRAS) by the FDA when used as a nutrient supplement. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated zinc sulfate and established guidelines for its use. While zinc is essential, very high intakes can interfere with copper absorption and may cause gastrointestinal upset.

Allergen info

Zinc sulfate is not derived from any of the FDA's major allergens and does not contain gluten.
