Evidence supporting the use of: Vitamin C
For the health condition: Cough (dry)
Synopsis
Source of validity: Traditional
Rating (out of 5): 1
Vitamin C (ascorbic acid) has long been associated with immune support and the prevention or treatment of respiratory ailments, including the common cold. Its use to help with a dry cough is primarily rooted in traditional and popular health practices rather than robust scientific validation. Historically, vitamin C became prominent in the 20th century through the advocacy of Nobel laureate Linus Pauling, who suggested it could prevent and treat colds and related symptoms, including cough. This led to widespread popular use of vitamin C supplements during cold and flu seasons.
However, scientific research does not strongly support the use of vitamin C for treating a dry cough specifically. Meta-analyses and systematic reviews, such as those by the Cochrane Collaboration, have found that while regular vitamin C supplementation may slightly reduce the duration and severity of cold symptoms in the general population, its effect on cough has not been specifically established, and it does not consistently prevent or treat colds when started after symptom onset. The evidence for using vitamin C to relieve a dry cough is therefore considered weak (rated 1 out of 5), and its use is primarily justified by tradition and anecdotal reports rather than high-quality clinical trials.
In summary, while vitamin C is widely used for respiratory symptoms, its specific benefit for dry cough is not scientifically validated and remains a traditional remedy with minimal supporting evidence.
