At least one study demonstrated that routine copper supplementation (1-3 mg per day) could boost the antioxidant
function of superoxide dismutase enzyme.
Dosage Ranges
General Health Benefits
Often 1-3 mg of copper is included as part of a multiple vitamin and mineral supplement. This may boost antioxidant
function and support cardiovascular, bone and connective tissue integrity in persons with sub-optimal dietary intake,
which is not an infrequent circumstance.9
Side Effects and Toxicity
Patients with Wilson’s Disease should not ingest supplements that contain copper.1 Generally, copper toxicity is rare,
but the lethal dose may be as low as 3,500 mg.10 Taking up to 3 mg per day as part of a multiple vitamin and mineral
is considered safe for otherwise healthy adults. A daily intake of 20 mg of copper produces nausea and vomiting.1,9
Drug-Nutrient Interactions

1. Clofibrate11
2. Fenofibrate11
