Bovine Colostrum

Bovine colostrum is the nutrient-dense first milk produced by cows within the initial hours after calving, representing a uniquely concentrated biological matrix that differs fundamentally from regular milk. This spray-dried, first-milking powder is standardized to ≥30% immunoglobulin G (IgG) and also delivers bioactive growth factors such as IGF-1 and TGF-β, along with lactoferrin, proline-rich polypeptides, and a spectrum of cytokines that collectively support intestinal epithelial integrity and mucosal immune modulation. Formulators select this ingredient for its unmatched bioactive complexity and clinical backing in gut-health applications, where no single synthetic compound can replicate the synergistic action of its naturally co-occurring immune and growth factors.
