The Claim
High-dose zinc acetate lozenges (>75 mg/day) exhibit efficacy in treating the common cold in adults, and this efficacy is not modified by allergy status, smoking history, baseline cold severity, age, gender, or ethnic group.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking high-dose zinc lozenges helps adults with colds feel better, and it works the same way for everyone—no matter if they have allergies, smoke, how bad their cold is, their age, gender, or background.
