The Claim
Prophylactic vitamin C supplementation reduces the duration of the common cold by 8% (95% CI 3-13%) in adults and 13.6% (95% CI 5-22%) in children, based on an analysis of 9676 respiratory episodes.
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 regularly might help you get over a cold faster—about 8% quicker for adults and 14% for kids, according to a big study.
