BioStacksWhy Copper for Skin
Copper plays a supporting role in skin. Required for iron transport (via ceruloplasmin), collagen formation, and antioxidant defense through superoxide dismutase (SOD). Copper and zinc compete for absorption—high-dose zinc supplementation (above 50 mg/day) can induce copper deficiency over time.
Effective dosing
Most evidence supports 1000–2000 mcg of copper daily. Products below this range may not deliver meaningful results.
Form and bioavailability
Avoid copper oxide — poorly absorbed. Look for copper bisglycinate or copper gluconate for better absorption.
The evidence behind copper
Research supporting copper for skin is rated as strong. Essential cofactor for iron transport via ceruloplasmin and collagen formation via lysyl oxidase Learn more
