What is the recommended dosage for Zinc?

General: 8-11 mg/day; Cold Treatment: 75-100 mg/day elemental zinc (lozenges, within 24h of onset, up to 2 weeks); Immune Support: 15-30 mg/day

What are the side effects of Zinc?

Potential side effects include: Nausea and vomiting (especially on an empty stomach), Metallic taste in the mouth, Copper depletion with chronic high-dose use (>40 mg/day), Headache and diarrhea.

What is zinc and how does it support the immune system?

Zinc is an essential trace mineral required for the development and function of immune cells including neutrophils, natural killer cells, and T-lymphocytes. Zinc deficiency impairs both innate and adaptive immunity and is associated with increased infection susceptibility.

What dosage of zinc has been studied for immune health?

Clinical trials have used zinc at doses of 15–75 mg per day for immune outcomes. For reducing cold duration, zinc lozenges providing 75 mg or more of elemental zinc per day (started within 24 hours of symptom onset) have shown the most consistent results.

What are the potential side effects of zinc supplementation?

Common side effects include nausea, metallic taste, and gastrointestinal discomfort. Chronic intake above 40 mg per day may cause copper deficiency and associated anemia. Intranasal zinc products have been linked to irreversible loss of smell and should be avoided.

About

Zinc is an essential trace mineral required for the development and function of neutrophils, natural killer cells, and T lymphocytes. It acts as a signaling molecule for immune cells and supports thymic function and T-cell maturation. Meta-analyses demonstrate zinc lozenges at 75+ mg/day may reduce cold duration by 33% when started within 24 hours of onset.

How It Works

Essential trace mineral required for development and function of neutrophils, NK cells, and T lymphocytes; acts as a signaling molecule for immune cells and supports thymic function and T-cell maturation.
