Beta-Defensin vs Lactoferrin
A side-by-side research comparison of Beta-Defensin and Lactoferrin across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Beta-Defensin | Lactoferrin |
|---|---|---|
| Full name | Human Beta-Defensin Peptides | Lactoferrin (Iron-Binding Glycoprotein) |
| Category | Immune Support | Immune Support |
| Status | Research compound | Dietary supplement (GRAS) |
| Mechanism | Form pores in microbial membranes causing lysis, recruit immune cells via CCR6 receptor chemotaxis, and bridge innate and adaptive immunity by activating dendritic cells. | Sequesters iron from pathogens (bacteriostatic), directly disrupts bacterial membranes, activates NK cells and macrophages, and modulates inflammatory cytokines. |
| Molecular weight | 4000-5000 Da | 80000 Da |
| Half-life | ~2-4 hours | ~4-8 hours (oral absorption of fragments) |
| Bioavailability | Primarily local/mucosal activity | ~15-25% (oral, as bioactive fragments) |
| Typical dose | 50-200 mcg | 200-600 mg |
| Frequency | Daily or as needed | 1-2x daily |
| Route | Topical or subcutaneous | Oral capsule or powder |
