What is the recommended dosage for Copper?

General: 900 mcg/day (RDA); Skin Health: 900 mcg-2 mg/day

What are the side effects of Copper?

Potential side effects include: Nausea and vomiting (at high doses), Liver toxicity (chronic excess), Zinc depletion with long-term high-dose use.

What is copper and how may it relate to skin health?

Copper is a trace mineral essential for lysyl oxidase, the enzyme that cross-links collagen and elastin fibers. It is also required for melanin production via tyrosinase. Copper peptides are well-established in topical skincare for wound healing and anti-aging. Oral copper supplementation is typically addressed through diet or multivitamins.

What is the recommended intake of copper for skin health?

The RDA for copper is 900 mcg for adults. Copper deficiency is uncommon in developed countries but can occur with high zinc supplementation (which inhibits copper absorption). Copper-rich foods include liver, shellfish, nuts, and dark chocolate. Supplemental copper is rarely needed unless zinc supplementation creates a deficiency.

What are the potential side effects of copper supplements?

Excessive copper intake causes nausea, vomiting, abdominal pain, and at high doses, liver damage. The tolerable upper intake level is 10,000 mcg (10 mg) daily. Wilson disease patients must avoid copper supplements. Copper supplements should generally only be taken if zinc supplementation has created a documented copper deficiency.

About

Copper is an essential cofactor for lysyl oxidase (collagen/elastin cross-linking), tyrosinase (melanin synthesis), and superoxide dismutase (antioxidant defense). The copper-zinc balance is critical — supplementing one without the other can cause depletion. Topical copper peptides (GHK-Cu) have stronger evidence than oral copper.

How It Works

Essential cofactor for lysyl oxidase (collagen/elastin cross-linking), tyrosinase (melanin synthesis), superoxide dismutase (antioxidant defense), and cytochrome c oxidase (mitochondrial energy); supports dermal connective tissue integrity and wound healing.
