What to know
Rarely supplemented alone. Its main relevance is the flip side of zinc: chronic high zinc depletes copper, so heavy zinc users should watch this balance.
Interactions & cautions
- High-dose zinc is the main cause of copper deficiency.
Do you actually need it?
Only relevant if you take a lot of zinc long-term.
