The Claim
High-dose zinc acetate lozenges produce therapeutic effects on common cold symptoms that extend beyond the pharyngeal region, with nasal symptoms demonstrating improvement comparable in magnitude to throat symptoms.
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.
Zinc lozenges help with cold symptoms not just in your throat where the zinc is strongest, but also in your nose just as much.
See the scientific wording
The therapeutic effects of high-dose zinc acetate lozenges on common cold symptoms are not limited to the pharyngeal region where zinc concentration is highest, as nasal symptoms show similar magnitude of improvement to throat symptoms.
What the research says
1 studyThe study found that zinc lozenges helped both throat and nose cold symptoms about the same amount, showing they don't just work in the throat where the lozenge dissolves.
