The Claim
Many people believe that taking Vitamin C can prevent them from catching colds. This myth stems from the widespread idea that boosting vitamin intake will fortify the immune system against infections.
Origin
This belief originated from early studies in the 1970s by Linus Pauling and has been perpetuated by marketing claims and popular media.
What Science Says
Research indicates that while Vitamin C does not prevent colds in the general population, it may reduce the duration and severity of cold symptoms when taken regularly. A meta-analysis of randomized controlled trials found that regular supplementation can decrease the duration of colds by 8% in adults and 14% in children. However, its preventive effects remain unsubstantiated.
Verdict
Partially True
