The Claim
Zinc acetate lozenges release 100% ionic zinc at physiological pH 7.4, while zinc gluconate releases 72% ionic zinc, and other zinc compounds release much less or none, which explains the varying efficacy results observed in clinical trials.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Different types of zinc lozenges release zinc in different amounts when they dissolve in your mouth, and this affects how well they work in studies.

Zinc acetate lozenges release 100% ionic zinc at physiological pH 7.4, while zinc gluconate releases 72% ionic zinc, and other zinc compounds release much less or none, explaining the varying efficacy results across clinical trials.
What the research says
1 studyStudy: Zinc lozenges as cure for the common cold – A review and hypothesis
The study directly shows that zinc acetate lozenges release all their zinc in the active form, while zinc gluconate releases only 72%, just like the claim says, and this explains why some cold lozenges work better than others.
