The Claim
Zinc gluconate lozenges administered every 2 hours during common cold symptoms reduce the median duration of symptoms from 7.6 days to 4.4 days compared to placebo, as demonstrated in a randomized controlled trial involving patients with common cold.
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 couple of hours when you have a cold might help you get better faster, cutting the time you feel sick from about a week to just over four days.
