The Claim
Ionic zinc competes with ICAM-1 receptors on nasal epithelial cells and rhinoviruses, preventing viral attachment and replication, which explains its antiviral and anti-inflammatory effects in common cold treatment.
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.
Zinc stops cold viruses from sticking to your nose cells and making copies of themselves, which helps fight off the cold and reduce swelling.
