What do your copper levels mean?

The short answer

Nobody we follow has put a number on your copper level. They talk about the dose you take, not the level in your blood.

Your lab prints 80–155 µg/dL. That range exists to catch disease, not to describe your best.

Labs print different ranges by sex: about 80–155 µg/dL for women and 70–140 for men.

What copper measures

The copper circulating in your blood.

Copper and zinc compete for absorption, so the two go together when you take either as a supplement.
