The Claim

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 pills can help healthy people get over colds faster, meaning they spend less time stuck at home or missing school—about 15% less time, according to some studies.
