What the research says.
A quick, data-only summary. The full evidence, dosing, and sources are below.
Copper is a mineral most often used for iron metabolism, connective tissue health, antioxidant defense. NutriStack rates the overall evidence as moderate. A typical adult dose is 1–2 mg daily, commonly taken as copper bisglycinate. This profile indexes 18 sources.
The bottom line
Evidence rating moderate. Most-documented uses: iron metabolism, connective tissue health, antioxidant defense. 18 sources indexed (2002–2025), with 0 interaction records on file.
How it works, mechanistically.
Core mechanism
Cofactor for ceruloplasmin (ferroxidase for iron metabolism), cytochrome c oxidase (electron transport chain), superoxide dismutase (SOD, antioxidant), lysyl oxidase (collagen/elastin cross-linking), and dopamine beta-hydroxylase (norepinephrine synthesis).17,9
Dosing & protocol.
Balance with zinc (1-2mg copper per 15mg zinc); competes with zinc for absorption3,6
What it actually costs.
Real-world pricing across three quality tiers. Assumes Copper Bisglycinate.
Assumes 1-2 mg/day. Vendor basis: NOW/iHerb, Vitacost, Pure Encapsulations, and Amazon marketplace; chelated copper remains inexpensive. Updated 2026-05-28.
The same dose, as food.
How much you'd eat to match a supplemental dose.
Shellfish and organ meats provide even more.
Food can cover replacement doses unless zinc intake is very high.
