Copper Bisglycinate

Copper bisglycinate is a chelated form of copper bound to two glycine amino acids for enhanced absorption and reduced gastrointestinal irritation. It functions as a cofactor for essential enzymes including cytochrome c oxidase, superoxide dismutase, and lysyl oxidase that support cellular energy production, antioxidant defense, and connective tissue formation.

Origin & History

Copper bisglycinate is a chelated form of copper, where copper ions are bound to glycine, an amino acid, enhancing its absorption and bioavailability.

Historical & Cultural Context

Copper has been used for its medicinal properties since ancient times, with evidence of its use in ancient Egypt and Rome.

Health Benefits

- Supports the formation of red blood cells and hemoglobin, essential for oxygen transport and energy production. This is vital for overall vitality and endurance. - Enhances immune system function by supporting the activity of white blood cells, crucial for fighting infections. - Promotes cardiovascular health by maintaining healthy blood vessels and reducing the risk of atherosclerosis. - Supports bone health by aiding in the formation of collagen, which is important for bone strength and integrity. - Enhances skin health by promoting collagen production, leading to a more youthful and firm appearance. - Supports cognitive function by aiding in the synthesis of neurotransmitters, which are essential for brain health and mood regulation. - Aids in energy metabolism by acting as a cofactor for enzymes involved in energy production, helping to reduce fatigue.

How It Works

Copper bisglycinate delivers copper ions that serve as cofactors for cytochrome c oxidase in mitochondrial electron transport, enabling ATP synthesis. The mineral also activates lysyl oxidase for collagen and elastin cross-linking, and functions in superoxide dismutase to neutralize reactive oxygen species. The glycine chelation protects copper from precipitation and enhances intestinal absorption through amino acid transporters.

Scientific Research

Research indicates that chelated forms like copper bisglycinate are better absorbed by the body compared to inorganic forms. Studies support its role in maintaining healthy connective tissues and immune function.

Clinical Summary

Limited clinical trials have specifically studied copper bisglycinate, with most copper research using other forms like copper sulfate. A 2019 study of 42 adults found chelated copper supplements increased serum copper levels 23% more effectively than inorganic forms over 8 weeks. Observational studies link adequate copper intake (0.9mg daily) to reduced cardiovascular disease risk and improved immune markers. Evidence for bisglycinate's superior bioavailability comes primarily from comparative absorption studies rather than outcome-based trials.

Nutritional Profile

- Essential trace mineral. - Chelated for improved absorption. - Found in nuts, seeds, and organ meats.

Preparation & Dosage

Typical dosage ranges from 1 to 3 mg per day. Consult a healthcare provider before use.

Synergy & Pairings

Zinc, Vitamin C, Iron, Manganese, Selenium

Safety & Interactions

Copper bisglycinate is generally well-tolerated at doses up to 3mg daily, with fewer gastrointestinal side effects than copper sulfate. High doses above 10mg can cause nausea, vomiting, and liver damage. Zinc supplementation can interfere with copper absorption, potentially causing deficiency with long-term use. Copper may reduce absorption of quinolone antibiotics and should be taken 2-6 hours apart from these medications.
