The evidence in words
Safety profile

Interactions to respect
Zinc — The reason it's on the map — zinc drives copper down.
What Copper is
Copper is an essential trace mineral cofactor for iron metabolism, connective-tissue crosslinking, and antioxidant enzymes. Frank dietary deficiency is uncommon; the usual cause of low copper is induced deficiency from high-dose zinc.
The honest bottom line
Not a standalone supplement for most people — its job is to keep high-dose zinc from causing a copper deficiency.
