The Claim
Zinc gluconate lozenge therapy administered eight times daily for 5-7 days does not reduce the frequency or duration of viral shedding in adults with experimentally induced rhinovirus infections, indicating it does not inhibit viral replication or transmission potential.
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 lozenges several times a day for about a week doesn't help reduce how often or how long people with colds shed the virus, meaning it doesn't stop the virus from copying itself or spreading to others.

What the research says
1 studyThe study gave people zinc lozenges exactly as described and found they didn't stop the virus from spreading, which matches what the claim says.
