If you're taking high-dose zinc, this is the copper to pair with it: 2mg of elemental **copper** in a well-absorbed glycinate form, roughly twice the 0.9mg daily requirement and comfortably under the 10mg safe upper limit. Zinc and copper compete for absorption, so sustained zinc above 50mg a day can quietly drain your copper stores, and this offsets that.

Beyond balancing zinc, copper is a building block for collagen and connective tissue, which is where its modest skin relevance comes from. The glycinate form absorbs efficiently, so the full 2mg is available for your body to use.

For most people, diet plus a basic multivitamin already covers copper, so a standalone bottle is only worth buying if your zinc intake is high or a practitioner has flagged low copper. If that's not you, you probably don't need it.
