Zinc and the Common Cold: What You Need to Know

What does zinc do for the body? Zinc is an essential trace element vital for immune function, wound healing, and DNA synthesis. It supports over 300 enzymes and the proper function of immune cells like T-cells and macrophages. Zinc also aids in the production of antibodies that fight infections.

A recent review in the Cochrane Database of Systematic Reviews found that zinc supplements might not prevent colds, but taking zinc at the onset of symptoms can reduce the duration by about two days. This represents a 10-20% decrease in illness length, which is clinically significant.

Takeaways:
1. Zinc element in immunity: vital for immune cell function and enzyme activity, making it crucial in fighting infections.
2. Supplementation: Zinc gluconate and zinc acetate lozenges may effectively reduce cold duration if taken within 24 hours of cold symptoms.
3. Zinc supplementation reduces sick days of the common cold, but does not affect the odds of catching a cold or symptom severity.
4. Zinc deficiency: Can lead to significant health issues, emphasizing the need for adequate intake.

Safety note: Zinc supplements are generally well-tolerated, but high doses can cause nausea and gastrointestinal distress. Do not exceed the Tolerable Upper Intake Level of 40 mg/day regularly for adults without medical supervision.

What zinc should I take? Zinc gluconate and zinc acetate lozenges can be effective for boosting the immune system during colds. They can reduce the duration of symptoms if taken at the onset of illness. Consult your healthcare provider before starting any supplement regimen.
