Calcium bisglycinate

Calcium bisglycinate (CAS 35947-07-0) is a calcium salt of the amino acid glycine, also known commercially as Calcium Glycinate or Calcium Chelazome. It carries no assigned E-code and is distinct from inorganic calcium salts due to its chelated structure, which improves mineral bioavailability in biological systems.

In food and nutritional supplement manufacturing, calcium bisglycinate serves as a bioavailable calcium source where the glycine ligand facilitates intestinal absorption more effectively than carbonate or phosphate forms. In animal feed formulations, it delivers both calcium and glycine simultaneously, supporting bone mineralisation and metabolic function without the digestive load of inorganic alternatives.

Calcium bisglycinate is supplied in food-grade and feed-grade forms, typically as a powder, and is subject to REACH registration requirements within the EU. Procurement should confirm compliance with FCC specifications for food applications and relevant feed additive regulations under EU 2017/2017 where applicable. Standard packaging formats vary by supplier.
