The Claim
A linear dose-response relationship exists between zinc ion availability scores of lozenges and changes in duration of common colds, with higher positive zinc ion availability scores associated with greater reductions in common cold duration.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
This claim says that zinc lozenges might help shorten colds, and the more zinc your body can use from them, the faster your cold might go away.
See the scientific wording
A linear dose-response relationship exists between zinc ion availability (ZIA) scores of lozenges and changes in duration of common colds, with higher positive ZIA scores associated with greater reductions in cold duration.
What the research says
1 studyStudy: Zinc ion availability--the determinant of efficacy in zinc lozenge treatment of common colds.
The study looked at zinc lozenges and found that ones with more available zinc ions shorten colds more, exactly as the claim says, so it supports the idea.
