What it is

Cupric sulfate is an inorganic salt that is a form of copper. It is typically produced by reacting copper metal or copper oxide with sulfuric acid. It appears as a blue crystalline solid.

Why it's used

Cupric sulfate is used as a nutrient to fortify foods and beverages, particularly those aimed at specific dietary needs like infant formulas or nutritional drinks. It can also serve as a food colorant and a preservative in some applications.

Health notes

In the U.S., cupric sulfate is permitted as a nutrient supplement in food under certain conditions, as defined by the FDA. Copper is an essential mineral for human health, but excessive intake can be harmful. JECFA has evaluated copper sulfate and established an acceptable daily intake. Evidence does not suggest adverse effects from typical dietary intake of copper.

Allergen info

Cupric sulfate is not derived from any of the 9 FDA major allergens. It does not contain gluten.
