Probiotic, Cranberry, and Vitamin C Combination May Finally Work For UTIs

A study found that a combination of cranberry supplement (120 mg cranberries, with a minimum proanthocyanidin content of 32mg), the probiotic Lactobacillus rhamnosus, and vitamin C (750 mg) three times a day was enough to prevent the recurrence of urinary tract infections (UTIs) for the majority of women in this small (36 patient) study. At 6 months there was a 61% success rate. No side effects were reported.

These are wonderful results, but why aren't more studies also being done on the effective product D-Mannose? The one study (see post) that I found looking at D-Mannose found an 85% success rate at 6 months. It is especially effective against E.coli, which is the cause of the majority of UTIs. But the great news is that finally women have some effective and safe treatments to try, and the wonderful possibility of getting off the vicious cycle of repeated courses of antibiotics.

Effectiveness of a Combination of Cranberries, Lactobacillus rhamnosus, and Vitamin C for the Management of Recurrent Urinary Tract Infections in Women: Results of a Pilot Study.

Urinary tract infections (UTIs) are common in women and many patients with recurrent UTIs do not eradicate the condition albeit being treated with multiple courses of antibiotics. The use of nutritional supplements might reduce the risk of recurrent UTIs. However, the role of supplements taken as single agents appears to be limited. We hypothesized that a combination of cranberries, Lactobacillus rhamnosus, and vitamin C might produce a clinical benefit due to their additive or synergistic effects. We prospectively enrolled 42 consecutive women with recurrent UTIs treated with 120mg cranberries (minimum proanthocyanidin content: 32mg), 1 billion heat-killed L. rhamnosus SGL06, and 750mg vitamin C thrice daily for 20 consecutive days. Patients were advised to stop taking these supplements for 10 d and then to repeat the whole cycle three times. Patients were contacted three mo and six mo following the end of the administration of these supplements and evaluated with a semistructured interview and urinalysis. Responders were defined as the absence of symptoms and negative urinalysis or urine culture. Follow-up data were available for 36 patients. Overall, 26 (72.2%) and 22 patients (61.1%) were responders at the 3-mo and 6-month follow-up. No major side effects were recorded. The administration of cranberries, L. rhamnosus, and vitamin C might represent a safe and effective option in women with recurrent UTIs.
