Colostrum (bovine)
Immune · Immunoglobulin-rich milk
Tier B-
What this is
First 24-hour colostrum has highest IgG concentration. Pasteurization reduces activity modestly. Commercial quality varies enormously. Popular in athlete recovery protocols and gut permeability/'leaky gut' interventions with moderate evidence.
Mechanism
First-milk from cows containing IgG, IgA, IgM, lactoferrin, growth factors (IGF-1, TGF-β), and bioactive peptides; oral IgG transfers immune memory locally in gut
Dose & route
10-20 g/day PO
