Can You Take Copper and GHK-Cu Together?

Use extra care with this pair

The short answer

GHK-Cu (copper peptide) already provides bioavailable copper. Combining with additional copper supplements may lead to excessive copper intake, risking copper toxicity and oxidative stress.

How to arrange timing

Avoid supplementing additional copper when using GHK-Cu, as it already provides copper. Monitor copper levels if combined.

Important context

Whether supplements suit you together also depends on dose, product formulation, health conditions, and medication use. Ask a doctor or pharmacist first if you take medication, are pregnant or breastfeeding, or have a chronic condition.
