Copper glycinate

Copper glycinate (CAS 18253-80-0), also known as cupric glycinate hydrate, is a chelated copper-amino acid complex used as a bioavailable copper source.

Where is Copper glycinate used?

• Dietary supplements and functional foods: fortification where copper deficiency correction or antioxidant enzyme support is the goal
• Animal feed: organic trace mineral source in poultry, swine and aquaculture feeds
• Pharmaceuticals: mineral supplement preparations specifying chelated copper
• Food fortification: copper source for clean-label or amino acid-chelated mineral declarations
• Its chelated form improves copper absorption compared to inorganic copper salts.
• Parenteral supplementation in animals as a source of copper replacement.
• Nutritional supplements, nutricosmetics, and sophisticated nutrition concepts.

Good to know: Buyers should confirm purity levels and copper content per lot, as these vary by manufacturer. Quality may be verified against standards such as FCC or USP depending on the grade.

Formulation notes

• Can increase copper absorption by up to 50% compared to copper sulfate.
• Zinc and copper compete for absorption in the intestine, so maintaining a balance is crucial.

Typical specification

• Assay of 98.00 to 100.00.
• Blue to dark blue solid.
• Available with low microbial count: E. coli absent.
• pH of approximately 8 (1% solution).

Regulatory status

• Classified as acute toxicity, oral category 4 (H302) under GHS.
