The Claim
Supplementation with 1000 mg vitamin C plus 10 mg zinc reduces rhinorrhea duration by 9-27% in patients with the common cold, though this reduction was not statistically significant in individual randomized controlled trials.
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 vitamin C and zinc together might help shorten how long your nose runs when you have a cold, but studies haven't proven it definitely works.

What the research says
1 studyStudy: A Combination of High-Dose Vitamin C plus Zinc for the Common Cold
