What it is

Copper sulfate is an inorganic salt that appears as blue crystals. It is produced by reacting copper metal or copper oxides with sulfuric acid. It is sometimes used in food processing.

Why it's used

Copper sulfate is sometimes used as a nutrient to fortify foods, particularly in animal feed. In some regions, it has been used as a food additive to preserve the color of certain fruits and vegetables, and as a firming agent.

Health notes

In the U.S., copper is an essential nutrient, and copper sulfate can be used as a source of copper in animal feed. The FDA has not approved copper sulfate for direct use in human food. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated copper sulfate and established an acceptable daily intake. Evidence regarding the effects of copper sulfate at typical human intake levels is limited.

Allergen info

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