What is a normal copper level?
The short answer
A typical US lab prints a normal copper range for your sex: 80–155 µg/dL for women, 70–140 µg/dL for men. That range exists to catch disease, not to describe your best.
Nobody we follow has put a number on your copper level. They talk about the dose you take, not the level in your blood.
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.
Common questions
What is a normal copper level?
Most US labs print 80–155 µg/dL. Your report grades you against that range. It 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 does your copper number mean?
On a typical lab range, under 80 µg/dL is low, 80 to 155 is normal and over 155 is high. Your own report prints its range next to your number, and that is the one your lab uses. Nobody we follow has drawn a line inside that range. Labs print different ranges by sex: about 80–155 µg/dL for women and 70–140 for men.
What does the copper test measure?
The copper circulating in your blood. Copper and zinc compete for absorption, so the two go together when you take either as a supplement.
Why is there no target here?
Because the people we follow discuss copper as something you eat or take. Nobody has said what the level in your blood should be.
