Lactoferrin vs Thymosin Alpha-1
A side-by-side research comparison of Lactoferrin and Thymosin Alpha-1 across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Lactoferrin | Thymosin Alpha-1 |
|---|---|---|
| Full name | Lactoferrin (Iron-Binding Glycoprotein) | Thymosin Alpha-1 (Thymalfasin) |
| Category | Immune Support | Immune Support |
| Status | Dietary supplement (GRAS) | Approved internationally (not FDA-approved) |
| Mechanism | Sequesters iron from pathogens (bacteriostatic), directly disrupts bacterial membranes, activates NK cells and macrophages, and modulates inflammatory cytokines. | Activates toll-like receptors (TLR2, TLR9) on dendritic cells, promotes T-cell maturation and differentiation, enhances NK cell cytotoxicity, and modulates cytokine profiles. |
| Molecular weight | 80000 Da | 3108.3 Da |
| Half-life | ~4-8 hours (oral absorption of fragments) | ~2-3 hours |
| Bioavailability | ~15-25% (oral, as bioactive fragments) | ~85% subcutaneous |
| Typical dose | 200-600 mg | 1.6-3.2 mg |
| Frequency | 1-2x daily | 2-3x per week |
| Route | Oral capsule or powder | Subcutaneous injection |
