Colostrum is the first milk produced by mammals immediately after birth, containing concentrated immune factors (immunoglobulins, lactoferrin, growth factors) that provide passive immunity and promote gut barrier development. Bovine colostrum is used therapeutically for gut healing and immune support.
Colostrum contains: (1) Immunoglobulins (IgG, IgA) providing passive immunity and binding gut pathogens, (2) Lactoferrin with antimicrobial and iron-binding properties, (3) Growth factors (IGF-1, TGF-Ξ², EGF) promoting intestinal epithelial repair, (4) Proline-rich polypeptides (PRPs) modulating immune responses, (5) Oligosaccharides acting as prebiotics, (6) Cytokines directing immune development. Together these factors seal leaky gut, reduce inflammation, support beneficial microbiota, and enhance systemic immunity.
Colostrum is a powerful intervention for leaky gut, inflammatory bowel conditions, athletic recovery, and immune dysfunction. It addresses the gut-inflammation nexus that prevents muscle building and healing. Particularly useful when patients 'do everything right' but fail to progress due to inflammatory load from gut barrier dysfunction.
- Contains IgG levels 100x higher than mature milk
- Growth factors promote intestinal cell proliferation and repair
- Lactoferrin concentration 7x higher than mature milk
- Reduces gut permeability (zonulin) by 30-70% in clinical studies
- IGF-1 content supports muscle protein synthesis and recovery
- PRPs can modulate both Th1 and Th2 responses (bidirectional immune regulation)
- Survives gastric acid to reach small intestine intact
- Typical therapeutic dose: 20-60g/day for gut healing
- Effects visible within 2-4 weeks of supplementation
- Leaky gut β directly heals intestinal barrier and reduces permeability
- Zonulin β reduces zonulin-mediated tight junction opening
- IgA β provides secretory IgA to support mucosal immunity
- IgG β contains high levels of IgG for passive immunity
- Lactoferrin β key antimicrobial component binding iron from pathogens
- IGF-1 β growth factor supporting tissue repair and muscle building
- TGF-beta β immunoregulatory cytokine in colostrum promoting tolerance
- EGF β epidermal growth factor accelerating epithelial healing
- Gut barrier β strengthens barrier through multiple mechanisms
- Tight junctions β supports tight junction protein expression
- Inflammation β reduces systemic inflammation by healing gut source
- Muscle protein synthesis β IGF-1 and growth factors support muscle building
