Does vitamin C help fight urinary tract infections?
There is limited evidence that vitamin C can help prevent or treat urinary tract infections. It may slightly acidify urine, but it is not a substitute for antibiotics.
Detailed Medical Explanation
Some studies have explored vitamin C (ascorbic acid) as a supportive measure for UTI prevention. High doses may lower urinary pH, creating an environment less favourable to bacterial growth, but the effect is modest and unproven for established infections. NICE and NHS do not recommend vitamin C as a sole therapy. NHS: UTI and vitamin C.
Clinical Context
Clinics do not recommend vitamin C alone for UTIs, but maintaining good nutrition may support overall immune function. Antibiotics remain the primary treatment.
Evidence-Based Approaches
NHS and NICE do not list vitamin C as a first-line or alternative UTI therapy. It may be used as a general dietary supplement, not as treatment.
