Copper
Also known as: Cu
Copper is a trace element needed for iron transport, collagen formation, hair and skin pigmentation and normal immune and nervous system function. A supplement is mainly worthwhile with long-term higher-dose zinc, which can cause copper deficiency.
What it is used for
- Normal iron transport, immunity and hair pigmentation – EFSA-approved claims for the basic role
- Prevention of copper deficiency with long-term zinc use – moderate evidence
- Benefit without deficiency – weak evidence
