Zinc Injection (Zinc Sulfate Injectable)
Injectable zinc provides rapid repletion for immune function, testosterone production, and wound healing. Telemedicine clinics prescribe it for patients with absorption issues or acute immune needs.
How it works
Essential cofactor for 300+ enzymes. Critical for T-cell maturation, NK cell activity, zinc finger protein transcription factors, testosterone synthesis, and wound healing metalloproteinases.
Key facts
- Molecular weight: 287.56 Da
- Half-life: Stored in tissues (~2-3 week turnover)
- Bioavailability: ~100% injectable
- Storage: Room temperature.
Dosing overview
- Typical dose: 5-10 mg elemental zinc
- Frequency: 1-2x per week
- Duration: Until optimal levels
- Route: Intramuscular or IV injection
Protocol notes
- Injectable zinc is dosed in small amounts (~5-10 mg elemental) once or twice weekly to correct deficiency.
- Used short-term for repletion, then maintained orally rather than injected indefinitely.
- Often paired with copper supplementation since long-term zinc depletes copper.
Reported benefits
- Immune system support
- Testosterone production
- Wound healing
- Thyroid function
- Antioxidant support
Possible side effects
- Injection site pain
- Nausea
- Copper depletion (long-term)
- Metallic taste
Research
- Zinc and immune cell function (2021): Zinc repletion improved T-cell and NK-cell counts by 30% in deficient adults within 4 weeks of injectable therapy.
