GHK-Cu Food & Supplement Interactions: What to Avoid and What Helps At a glance GHK-Cu is a naturally occurring tripeptide that binds copper(II) with high affinity (log K = 16.44) Zinc supplements at doses above 40 mg/day can displace copper from GHK and reduce peptide activity High-dose vitamin C (above 1,000 mg) may reduce Cu to Cu, altering the peptide's redox chemistry Copper-rich foods (liver, oysters, dark chocolate) do not interfere but may contribute to copper overload in high-dose protocols Iron supplements taken concurrently may compete for shared intestinal transporters relevant to topical copper absorption Chelating agents (EDTA, D-penicillamine, trientine) can strip copper from the peptide complex entirely Optimal injection timing is 60+ minutes before or after a meal No formal FDA drug interaction studies exist for compounded GHK-Cu How GHK-Cu Works: The Copper-Peptide Mechanism GHK-Cu functions as a copper delivery vehicle
