What is Copper Glycinate

Copper Glycinate and the commercially available products are hygroscopic blue powders, freely soluble in water and practically insoluble in ethanol and acetone. Soluble in water, it contains moderate concentrations of hydroxide ions and has a pH of about 7.0. It is used as a basic reagent to neutralize acids.

What is it for?

Added for nutritional purposes in food supplements.
It is used as a basic reagent to neutralize acids.

Safety

A conservative estimate of the dietary exposure was made based on a hypothetical intake from all sources (PARNUTS, food supplements and foods intended for the general population) at the tolerable upper intake levels for copper (5 mg/day), zinc (25 mg/day), calcium (2500 mg/day) and magnesium (250 mg/day). Assuming that the mineral amino acid chelates concerned in this opinion would entirely be ingested in the bisglycinate form the equivalent exposure to glycine would be around 12 mg glycine/day for copper bisglycinate.
The EFSA Panel concludes that the use of copper bisglycinate chelate as a source for copper added for nutritional purposes to food supplements, and of calcium bisglycinate chelate and magnesium bisglycinate chelate as sources for respectively calcium and magnesium added for nutritional purposes to foods for particular nutritional uses and food supplements, and of zinc bisglycinate chelate when used as a source for zinc in foods intended for the general population (including food supplements) and foods for particular nutritional uses, is not of safety concern.
