The Claim
Zinc gluconate lozenges containing 23 mg of zinc dissolved in the mouth every 2 wakeful hours after an initial double dose are associated with 86% of subjects becoming asymptomatic from common colds within 7 days, compared to 46% with placebo.
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 every few hours might help people get over a cold faster, with more people feeling better in a week compared to those who don't take them.

The study tested exactly what the claim said—zinc lozenges taken every few hours—and found that more people got better faster with zinc than with a fake pill, just like the claim states.
