Vitamin C, also known as ascorbic acid, has been investigated for its role in immune support and as an adjunct in infections, but not as a direct alternative to antibiotics. Scientific evidence suggests that Vitamin C may enhance immune function and reduce the severity and duration of certain infections, particularly viral infections like the common cold. Some in vitro and animal studies suggest Vitamin C may have mild antibacterial properties or support leukocyte function, but these effects are modest compared to antibiotics. There is limited clinical evidence from small studies suggesting that Vitamin C supplementation might reduce the incidence or improve outcomes in patients with infections, especially in those who are deficient in Vitamin C. However, the evidence for Vitamin C as an alternative to antibiotics is weak, and there is no robust clinical trial data supporting its use as a stand-alone treatment for bacterial infections. Most guidelines do not recommend Vitamin C as a replacement for antibiotics, but it may be used as an adjunct to support the immune response. Overall, while there is some scientific rationale for Vitamin C supplementation in infections, it should not be considered a true alternative to antibiotics for treating bacterial illnesses.
