Description
Spray-dried first-milking bovine colostrum standardized to immunoglobulin G content. Provides a complete profile of immune factors, growth factors, and bioactive peptides naturally present in the first secretion produced by cows after calving.
Cream to pale yellow free-flowing powder with a mild dairy flavor. Standardized to 20 percent, 25 percent, or 30 percent IgG depending on grade.
We supply food-grade Bovine Colostrum from manufacturers in China and supply partners with cross-border collection from New Zealand and the United States, holding ISO, Halal, Kosher and other certifications relevant to the product and production.
Common market grades include 20% IgG standard, 30% IgG premium, defatted and skim variants, and instantized grades for cold-water mixing in shakes and beverages. Collected within 24 to 72 hours of calving for premium classification.
Bulk and reduced-MOQ shipments. Batch-level COA covering IgG content, protein, lactoferrin, antibiotic residue, and microbiology.
Introduction
Colostrum is the immune-rich first secretion produced by mammals after parturition. Bovine colostrum contains IgG at concentrations roughly 100 times higher than mature milk, alongside lactoferrin, immunoglobulins IgA and IgM, growth factors including IGF-1 and TGF-beta, and a complex profile of bioactive peptides.
The nutraceutical use of bovine colostrum was established in New Zealand and the United States during the 1990s, with industrial spray-drying and IgG standardization protocols developed for shelf-stable product. Chinese capacity, much of it tied to dairy supply chains in Inner Mongolia and Heilongjiang, has expanded substantially since 2010.
The principal value driver is IgG content. Standard 20 percent IgG grades serve general-wellness markets; 30 percent IgG premium grades are used in sports nutrition and immune-focused formulations.
The dominant handling considerations are heat sensitivity of the immunoglobulins, which limits processing temperatures, and the dairy-allergen status, which must be disclosed in finished-product labeling.
