Copper Citrate
Copper citrate is a highly bioavailable chelated form of copper that serves as a cofactor for cytochrome c oxidase and lysyl oxidase enzymes. It supports cellular energy production, collagen synthesis, and iron metabolism through its essential role in oxidative enzyme systems.

Origin & History
Copper citrate is a salt of citric acid and copper, used as a dietary supplement to provide the essential mineral copper.
Historical & Cultural Context
Copper has been used since ancient times for its health properties, with historical uses in various cultures for treating ailments.
Health Benefits
- Supports energy production by aiding in iron absorption, enhancing cellular respiration efficiency. This leads to increased vitality and reduced fatigue. - Promotes healthy skin and connective tissue by stimulating collagen synthesis, which maintains skin elasticity and reduces wrinkles. - Enhances immune function by supporting the production of white blood cells, crucial for fighting infections and diseases. - Aids in the formation of hemoglobin and red blood cells, improving oxygen transport throughout the body. This can increase endurance and physical performance. - Supports brain health by facilitating neurotransmitter synthesis, which is essential for mood regulation and cognitive function. - Contributes to antioxidant defense by participating in the formation of superoxide dismutase, a key enzyme that protects cells from oxidative damage. - Regulates gene expression by acting as a cofactor for enzymes involved in DNA synthesis, crucial for cell growth and repair.
How It Works
Copper citrate dissociates in the gastrointestinal tract, releasing copper ions that bind to ceruloplasmin and other copper-transport proteins. The copper then serves as a cofactor for cytochrome c oxidase in mitochondrial electron transport, lysyl oxidase for collagen cross-linking, and ferroxidase for iron oxidation and transport.
Scientific Research
Studies show that copper citrate is an effective form for copper supplementation, supporting its role in enzymatic reactions and antioxidant defense.
Clinical Summary
Limited clinical trials exist specifically for copper citrate supplementation. Observational studies suggest copper deficiency affects 10-25% of elderly populations, with symptoms including anemia and connective tissue disorders. Small intervention studies (n=20-50) show copper supplementation can improve iron status markers within 4-8 weeks. Evidence quality remains moderate due to small sample sizes and short duration studies.
Nutritional Profile
- Provides essential copper mineral. - Enhanced bioavailability compared to some other forms. - Found in shellfish, nuts, and seeds.
Preparation & Dosage
Typical dosage ranges from 1 to 3 mg per day. Consult a healthcare provider before use.
Synergy & Pairings
Zinc, Vitamin C, Iron, Magnesium, Selenium
Safety & Interactions
Copper citrate is generally well-tolerated at doses under 10mg daily, with nausea and stomach upset occurring at higher doses. It can reduce zinc absorption when taken concurrently, requiring separated dosing. Contraindicated in Wilson's disease due to copper accumulation disorders. Pregnancy safety data is limited, though copper is essential for fetal development.
