Home Feeds Ingredients Organic Calcium Calcium Proteinate

Calcium Proteinate - Feed Ingredient

Calcium proteinate is a chelated mineral compound formed by binding calcium to amino acids or partially hydrolyzed proteins (peptides). This chelation process enhances the mineral’s solubility and stability, potentially improving its absorption and utilization compared to inorganic calcium sources like calcium carbonate or calcium phosphate.

In equine nutrition, calcium proteinate is used as a supplemental source of calcium to support skeletal structure, muscle function, and metabolic processes. It is typically included in mineral premixes, complete feeds, or targeted supplements where enhanced bioavailability of calcium is desired.

The following equine feeds, supplements and products contain Calcium Proteinate as an ingredient.
