The Claim
High-dose zinc acetate lozenges (>75 mg/day elemental zinc) reduce the duration of the common cold by approximately 3 days (36-40% reduction) in adults aged 20-50 years, based on a meta-analysis of three randomized controlled trials involving 199 patients.
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 can shorten how long you have a cold by about 3 days, especially for adults between 20 and 50 years old.
