What Does Copper Do?
Copper is a trace mineral that helps make red blood cells and supports energy production.
Copper is a trace mineral needed for energy production, iron absorption, and forming connective tissues. It also helps the body make melanin, which gives color to skin and hair. The mineral plays a role in supporting the immune system and maintaining strong blood vessels. Deficiency is rare but can cause fatigue, anemia, or brittle bones. The body requires only small amounts, but balance is key since too much can be harmful.
Copper is involved in making red blood cells by supporting iron metabolism.
It helps enzymes produce collagen and elastin for healthy skin and blood vessels.
The mineral supports brain and nerve function through neurotransmitter activity.
Both deficiency and excess can cause weakness, low immunity, or organ strain.

Which Copper Type Is Best?
Copper in copper bisglycinate form is well absorbed and gentle on the stomach.
The best type of copper supplement is usually in chelated form, such as copper gluconate or copper bisglycinate, which improves absorption and reduces stomach irritation. These forms are more bioavailable than inorganic ones like copper oxide. People generally only need copper supplementation if their diet lacks it or if they have specific medical needs. Copper should be balanced with zinc intake, since the two minerals compete in the body. The safest type is the one provided in carefully measured, low doses.
Copper gluconate and bisglycinate are absorbed efficiently and are gentle on the stomach.
Inorganic forms like copper oxide are less bioavailable and less effective.
Copper and zinc should be balanced, as too much of one reduces absorption of the other.
Small, regulated doses prevent the risk of copper buildup in tissues.
