The Claim
High-dose zinc acetate lozenges (80-92 mg/day) initiated within 24 hours of symptom onset reduce the total duration of common colds by 42% (95% CI: 35% to 48%) in adults, based on pooled data from 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 right when you start feeling a cold can shorten how long you're sick by almost half, according to studies in adults.
