D-Mannose for Chronic Urinary Tract Infections

Recurrent UTI are common among 20% of women, with many women experiencing three or more infections a year. The typical treatment is antibiotics, but long-term use increases the likelihood that those medicines won’t work against future infections.

A natural and effective option is a supplement called D-Mannose, a naturally occurring sugar found in a variety of fruits such as blueberry, apple, and cranberry. This sugar is the reason that cranberry juice is commonly recommended as a UTI treatment; it’s a lot easier, however, to get the recommended dosage from a D-mannose supplement.

Here’s how D-mannose works and why it’s so effective: it attaches itself to E. coli, a bacteria normally found in the intestinal tract but often proliferates in places it should not be, causing infections. D-Mannose triggers the bacteria to bind to it, instead of the urinary tract, and this helps your body flush out the bacteria during urination.

Natural medicine practitioners have long been using D-mannose to treat UTI in men and women. Recent studies comparing D-Mannose to both antibiotic and placebo have shown women taking D-Mannose had a significantly lower frequency of UTI and a lower incidence of side effects compared to those taking the antibiotic.

Talk with your holistic physician before taking D-Mannose as dose differs based on frequency and duration of infection, age, and other health factors.
