The Claim
Zinc gluconate lozenges (13.3 mg) reduce the median duration of experimental rhinovirus colds from 3.5 days to 2.5 days in symptomatic adults, representing a statistically significant reduction (P=0.035), but this effect was not observed with natural colds or with zinc acetate formulations.
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.
When adults with cold symptoms take zinc gluconate lozenges, their colds might get better faster, but this only worked in a special test setting and not with real-world colds or different zinc types.

Zinc gluconate lozenges (13.3 mg) reduce the median duration of experimental rhinovirus colds from 3.5 days to 2.5 days in symptomatic adults, representing a statistically significant reduction (P=0.035), but this effect was not observed with natural colds or with zinc acetate formulations.
What the research says
1 studyStudy: Effect of treatment with zinc gluconate or zinc acetate on experimental and natural colds.
The study gave people the exact same zinc lozenges mentioned in the claim and found they really did shorten colds by about a day, just like the claim says.
