Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Vitamin C (ascorbic acid) has been explored for its potential role in supporting the management of herpes simplex virus (HSV) infections, both orally and topically. The scientific evidence supporting its use, however, is limited and somewhat preliminary. Several in vitro studies have demonstrated that vitamin C possesses antiviral properties, which may inhibit the replication of HSV. For example, some laboratory research has shown that high concentrations of vitamin C can inactivate HSV-1 in cell cultures. Additionally, vitamin C is well known for its role in supporting immune function, potentially aiding the body’s response to viral infections in general. A few small clinical studies and case reports from the mid-20th century have suggested that high-dose vitamin C, particularly when administered intravenously, might reduce the severity or duration of herpes outbreaks. However, these studies often lack rigorous controls, have small sample sizes, and their findings have not been consistently replicated in larger, well-designed clinical trials. Vitamin C remains popular as a complementary therapy for herpes, largely due to its general immune-supporting reputation rather than strong disease-specific evidence. Current clinical guidelines do not recommend vitamin C as a primary or adjunctive treatment for herpes simplex infections. In summary, while there is a modest scientific rationale and some preliminary evidence, robust clinical validation is lacking, and the use of vitamin C for herpes should be considered experimental.
