Evidence supporting the use of: Vitamin C
For the health condition: Bronchitis
Synopsis
Source of validity: Traditional
Rating (out of 5): 2
Vitamin C has a long history of traditional use in supporting respiratory health, including conditions like bronchitis. The rationale stems from its well-known role in supporting immune function and its antioxidant properties, which are believed to help the body combat infections and reduce inflammation. Historically, vitamin C has been used as a general remedy for colds and respiratory infections, with the belief that it can shorten illness duration or reduce symptom severity.
However, scientific evidence specifically supporting vitamin C's efficacy in treating or preventing bronchitis is limited. Most clinical studies and meta-analyses have focused on vitamin C's effects on the common cold and upper respiratory tract infections, where benefits have been modest and often limited to individuals under physical stress or with low baseline vitamin C status. There is little robust clinical evidence directly linking vitamin C supplementation to improvements in acute or chronic bronchitis outcomes.
Some observational studies suggest that higher vitamin C intake is associated with better lung function and lower incidence of respiratory illnesses in general, but direct interventional trials on bronchitis are lacking or inconclusive. As such, while vitamin C continues to be used traditionally for bronchitis, current scientific support is weak and not specific to this condition. More research is needed to clarify its potential therapeutic role in bronchitis.
