The Claim
Ionized zinc concentration ranges from 100% in zinc acetate lozenges to 0% in certain commercial formulations, with only ionized zinc demonstrating antiviral effects.
What the research says
Challenges is higher
Challenge is ahead, but a single strong supporting 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.
Different zinc lozenges have different amounts of the active form of zinc, and only the active form fights viruses.

Ionized zinc concentration varies from 100% in zinc acetate lozenges to 0% in some commercial formulations, with only ionized zinc exhibiting antiviral effects.
What the research says
3 studiesStudy: Zinc acetate lozenges for the treatment of the common cold: a randomised controlled trial
The study tested zinc acetate lozenges and found they didn't help with colds, which goes against the idea that ionized zinc in these lozenges has antiviral effects.
Study: In vitro activity of zinc salts against human rhinoviruses
The study looked at zinc salts like those in lozenges and found they don't work well against cold viruses in lab tests, which goes against the claim that ionized zinc fights viruses.
