Description
COA-BACKED PROTEIN INGREDIENT
Lactoferrin Powder 95%
Lactoferrin is supplied as a purified bovine milk protein at 95.0%, released against a batch-specific certificate of analysis. Because it is a protein, the specification is written on the protein content, the moisture and the microbiological status rather than on a marker compound. The milk origin carries a labelling consequence, so it is stated on the specification. It is an ingredient for further processing and is not a finished consumer product.

Buyer Decision Guide
Agree the protein content, the analytical method, the moisture limit and the microbiological criteria before approval. Confirm the milk allergen declaration for the buyer’s label, and confirm the iron-binding or iron-saturation status if that is part of your specification.
- Protein content: 95.0%, released against the batch COA.
- Milk allergen declaration stated on the specification.
- Moisture limit and microbiological criteria reported per batch.
- Iron-binding status available on request.
- COA, specification sheet and safety data sheet accompany each shipment.
- Regulatory status, permitted uses and labelling are the buyer’s responsibility for the destination market.

How This Grade Differs
Lactoferrin is offered at different protein contents and from different sources, including bovine milk and recombinant material. Purity, source and the presence of other milk proteins all differ between grades, so they are not interchangeable without confirming the specification.
For a substitution review, compare botanical identity, plant part, assay target, analytical method, physical form and the current offered-batch COA.
