Colostrum vs Larazotide
A side-by-side research comparison of Colostrum and Larazotide across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Colostrum | Larazotide |
|---|---|---|
| Full name | Bovine Colostrum (IgG-Rich) | Larazotide Acetate (AT-1001) |
| Category | Gut Health | Gut Health |
| Status | Dietary supplement (GRAS) | Investigational (Phase 3) |
| Mechanism | 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. | Acts as a zonulin peptide antagonist, preventing zonulin-mediated disassembly of tight junction proteins (ZO-1, occludin, claudins). Maintains paracellular barrier integrity without systemic absorption. |
| Molecular weight | Complex mixture | 1026 Da |
| Half-life | IgG: ~2-4 hours in GI tract | Not systemically absorbed (local GI action) |
| Bioavailability | Oral - IgG survives gastric acid (~25-30%); growth factors act locally | Minimal systemic absorption (acts locally in GI lumen) |
| Typical dose | 5-20 g powder or 500-2000 mg capsules | 0.5-1 mg |
| Frequency | Daily on empty stomach | 3x daily before meals |
| Route | Oral (powder or capsule) | Oral capsule |
