Can You Take Copper and Zinc Together?
Space apart
Take these at different times
Long-term high zinc can deplete copper, balance the ratio and space doses.
Recommended spacing: at least 2 hours apart.
Can I take Copper and Zinc together?
Long-term high zinc can deplete copper, balance the ratio and space doses.
How it works
The mechanism
High-dose zinc induces metallothionein in enterocytes, which binds copper and traps it inside cells that are shed into the gut. Sustained intake above ~40 mg/day of zinc can cause copper deficiency over weeks to months.
Dose where it matters
When the interaction actually matters
A zinc-to-copper ratio between 8:1 and 15:1 is a common target. Anyone taking >25 mg zinc daily for more than a few weeks should consider 1–2 mg copper.
Who should care most
Who this matters for
People on chronic high-dose zinc (immune support stacks, denture-cream users, some cold protocols).
Evidence strength
Strong evidence
Supported by multiple controlled human studies.
