What are the potential health effects of copper?The normal adult requires approximately two to three milligrams of copper per person per day. More than 90% of your dietary need for copper is provided by food. Drinking water usually provides less than 10% of your daily copper intake.
Consumption of high levels of copper can cause nausea, vomiting, diarrhoea, gastric (stomach) complaints and headaches. Long term exposure over many months and years can cause liver damage and death.
