The Claim
Zinc gluconate lozenges are associated with a reduction in the average duration of common colds by approximately 7 days compared to placebo, as demonstrated in a clinical trial.
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 zinc gluconate lozenges when you have a cold might help you get better about 7 days faster than if you didn't take them, according to a study.
