E519 Cupric sulphate

What is Cupric sulphate (E519)?

Cupric sulphate (E519) is a food additive that acts as a stabilizer and preservative, particularly in processed foods and beverages. It is also used as a source of copper in fortified foods. This additive helps maintain the color and texture of food products while extending their shelf life.


Why do I have an intolerance?

Intolerance to cupric sulphate may arise from sensitivity to copper, which can cause gastrointestinal symptoms such as nausea, vomiting, and abdominal pain. The body needs copper in small amounts, but when too much is consumed, it can lead to copper toxicity, particularly in individuals who are sensitive to this metal.


What can I do about it?

If you have an intolerance to cupric sulphate, it is important to avoid foods that contain this additive. Be sure to check labels on processed and fortified foods, and opt for fresh alternatives whenever possible. Additionally, limiting your overall intake of copper-rich foods, such as shellfish and nuts, may help prevent symptoms from arising.
