Vitamin C (ascorbic acid) has been studied for its potential to support the immune system and enhance resistance to infections, but its use as a direct alternative to antibiotics is not well-supported by strong scientific evidence. Some laboratory and animal studies suggest that Vitamin C can modulate immune function, enhance phagocytosis, and potentially inhibit the growth of certain bacteria. Historically, Vitamin C has been used to prevent and treat scurvy, not as an antibiotic substitute.

Clinical studies in humans are limited and show mixed results. A few small trials have examined Vitamin C as an adjunct to antibiotics rather than a replacement, suggesting that it may reduce the duration or severity of some infections (e.g., respiratory infections) when used alongside standard treatments. There is, however, no robust clinical evidence demonstrating that Vitamin C alone can effectively treat bacterial infections or replace antibiotics.

Systematic reviews and meta-analyses generally conclude that while Vitamin C supplementation may reduce the incidence and duration of some viral infections (like the common cold) in certain populations, the evidence for antibacterial effects in humans is weak. Therefore, while Vitamin C has some immunomodulatory properties and a long history of traditional use for general health, it is not validated as a direct alternative to antibiotics.
