Vitamin C shows limited evidence for preventing UTIs, with mixed results from clinical studies. Some research suggests vitamin C may acidify urine and create an environment less favorable for bacterial growth, particularly E. coli which causes 85% of UTIs. A 2016 systematic review found modest reductions in UTI recurrence among women taking 100-500mg daily, but the effect was not statistically significant across all studies. Cranberry supplements containing vitamin C appear more effective than vitamin C alone. While generally safe, high doses above 1000mg daily can cause digestive upset and may increase kidney stone risk in susceptible individuals.
