What is it? / Overview

Copper is required for iron metabolism, connective tissue formation, and nervous system function. Deficiency most commonly occurs after prolonged high-dose zinc use or malabsorption.

How is it used? / Administration

Form: Copper bisglycinate

Typical dose studied: 1–2 mg/day when indicated

Timing: With food; separate from high-dose zinc supplements

Only supplement if deficiency risk exists. Do not combine with high-dose zinc without balancing copper.

What does it pair with?

Pairs well with:

Only relevant if taking zinc at a high dose or long-term — copper needs may increase — Chronic high-dose zinc intake can impair copper absorption and status over time.

How well does it work? / Evidence

✓ Well-established

Who should avoid it?

Interacts with: Separate from high-dose zinc

Already taking it? Assess zinc-to-copper balance. Wilson disease (a rare genetic copper-accumulation disorder) is a real but very rare contraindication -- copper supplementation would directly worsen it.
