Colostrum Research Guide

Full name: Bovine Colostrum (IgG-Rich)

The first milk produced after birth, rich in immunoglobulins (IgG), growth factors (IGF-1, TGF-β), lactoferrin, and proline-rich polypeptides. Supports gut barrier integrity, immune function, and mucosal healing.

How Colostrum Works

IgG antibodies bind gut pathogens and endotoxins. Growth factors (EGF, TGF-β) stimulate epithelial cell proliferation and repair. Proline-rich polypeptides modulate Th1/Th2 balance for immune regulation.

Dosing Protocol

• Typical dose: 5-20 g powder or 500-2000 mg capsules
• Frequency: Daily on empty stomach
• Duration: Ongoing or 8-12 week cycles
• Route: Oral (powder or capsule)

Reported Benefits

• Gut barrier repair
• IgG immune support
• Reduced gut inflammation
• Athletic recovery
• Reduced upper respiratory infections
• Growth factor delivery

Potential Side Effects

• Mild bloating initially
• Dairy sensitivity (contains lactose)
• GI discomfort (initial)
• Rare allergic reaction
