Bovine Colostrum

MODERATE EVIDENCESupplementLast updated

AVELOR SUMMARY

Bovine colostrum is the first milk produced by cows in the 24-48 hours after birth — packed with immunoglobulins (IgG, IgA, IgM), lactoferrin, growth factors (IGF-1, TGF-β), and PRPs (proline-rich polypeptides). It went from obscure bodybuilding supplement to mainstream after Andrew Huberman's endorsement and ARMRA's DTC marketing. Our research shows genuine evidence for: gut barrier protection (reduced exercise-induced gut permeability by 80%), upper respiratory infection prevention (reduced URTI incidence by 50%), and immune support. The IGF-1 content is the primary concern — it's present in biologically significant amounts and may matter for individuals with cancer risk factors.

WHAT IT DOES

Colostrum provides a "comprehensive immune package": (1) IgG binds and neutralizes gut pathogens, preventing attachment to intestinal epithelium; (2) lactoferrin chelates iron from bacteria (bacteriostatic), disrupts bacterial membranes (bactericidal), and has antifungal/antiviral activity; (3) growth factors (TGF-β, IGF-1, EGF) stimulate intestinal epithelial cell proliferation and tight junction formation — physically repairing the gut barrier; (4) PRPs modulate immune response (increase underactive immunity, calm overactive immunity); (5) oligosaccharides act as prebiotics, feeding beneficial Bifidobacteria. The gut barrier repair mechanism is particularly relevant for athletes (exercise opens tight junctions) and NSAID users (NSAIDs damage gut lining).

OPTIMAL DOSAGE

Look for: First-milking colostrum (highest IgG); grass-fed sourced; low-heat processed (preserves immunoglobulins); IgG content ≥20% by weight; USDA organic preferred
Avoid: High-heat pasteurized (denatures IgG); skim colostrum; second/third-milking; products not stating IgG content; added sugars or fillers
Minimum effective dose: 10g/day whole colostrum; 500mg concentrated IgG extract
Third-party tested brands: ARMRA, Sovereign Laboratories (Colostrum-LD — liposomal), Surthrival, Designs for Health
