The Claim
High-dose zinc acetate lozenges (>75 mg/day) reduce relative common cold duration by 36-40% compared to placebo in adults, based on pooled analysis of three randomized controlled trials.
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 every day might help adults get over colds faster—cutting how long you're sick by more than a third compared to not taking them.
