Is it true that zinc gluconate lozenges shorten the duration of the common cold?
Yes. Multiple meta-analyses and reviews report that properly composed zinc lozenges, including zinc gluconate, shorten the duration of the common cold by roughly 28-37% in adults. Some sources note the evidence is inconsistent or limited to adults, but the overall body of evidence supports the claim.
