Lactoferrin vs Zinc Injection
A side-by-side research comparison of Lactoferrin and Zinc Injection across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Lactoferrin | Zinc Injection |
|---|---|---|
| Full name | Lactoferrin (Iron-Binding Glycoprotein) | Zinc Sulfate Injectable |
| Category | Immune Support | Immune Support |
| Status | Dietary supplement (GRAS) | Compounded supplement |
| Mechanism | Sequesters iron from pathogens (bacteriostatic), directly disrupts bacterial membranes, activates NK cells and macrophages, and modulates inflammatory cytokines. | Essential cofactor for 300+ enzymes. Critical for T-cell maturation, NK cell activity, zinc finger protein transcription factors, testosterone synthesis, and wound healing metalloproteinases. |
| Molecular weight | 80000 Da | 287.56 Da |
| Half-life | ~4-8 hours (oral absorption of fragments) | Stored in tissues (~2-3 week turnover) |
| Bioavailability | ~15-25% (oral, as bioactive fragments) | ~100% injectable |
| Typical dose | 200-600 mg | 5-10 mg elemental zinc |
| Frequency | 1-2x daily | 1-2x per week |
| Route | Oral capsule or powder | Intramuscular or IV injection |
