The claim that vitamin C supplementation prevents the common cold receives a low confidence score of 20 due to evidence of circular-support and claim-drift. The cited literature contradicts the claim, revealing that differences in cold incidence and duration between vitamin C and placebo groups were statistically non-significant. Although high daily doses are widely touted, the empirical data does not demonstrate preventative efficacy, indicating substantial drift from the source evidence.
