Uses edit

Side effects edit

The U.S. Institute of Medicine (IOM) sets tolerable upper intake levels (ULs) for vitamins and minerals when evidence is sufficient. In the case of copper the adult UL is set at 10 mg/day.[4]

Copper gluconate is sold as a dietary supplement to provide copper. The typical dose is 2.0 mg copper per day. This is one-fifth what the IOM considers a safe upper limit. Long-term intake at amounts higher than the UL may cause liver damage.[4]
