This is purely anecdotal, but several years ago I owned a German shepherd who unfortunately inherited the gene for degenerative myelopathy.....multiple sclerosis in dogs. As the disease progresses up the spine, the bladder becomes either flaccid or tight, either of which can cause a UTI. My vet recommended that I give him D Mannose daily and he never was affected with an infection or with any side effect.

My urologist suggested that I try d-mannose after a year of battling E. Coli urinary tract infections treated with antibiotics followed by the UTI returning. The physician prescribed an antibiotic as usual, but told me that I should try the d-mannose powder 2 x daily. I can't believe how quickly the infection cleared up and remained clear! I'm going on my second month of no antibiotics and no UTIs. I'm not big on supplemental cures, but this was recommended by my urologist (UCSan Diego Health Care) so I tried it. I'm a believer!

Excellent product for keeping bacterial infection in urinary tract at bay. I usually notice results within 12 hours, and complete absence of symptoms within 24-36 hours.

I have had several UTI's in the past because of prostate problems. I have recently been taking a cranberry extract supplement once a day for about 2 years and haven't had any UTI's since.

I have a neurogenic bladder from multiple sclerosis and D-Mannose is the one supplement I ALWAYS take. I've been taking it for years and it rescued me from the horrid antibiotic/yeast infection UTI cycle.

When I take my d-mannose, I never get a full-blown UTI. I do not understand why the physicians do not make more women aware of this. They usually dismiss it and pull out their prescription pads! Maybe with these new findings, the physicians will feel more confident to recommend d-mannose for UTI management.

Don't get me wrong, when a full-blown UTI occurs, antibiotics are needed. But the d-mannose keeps me off chronic use of them.

D Mannose and Cran Naturelle have always worked for my family and friends at the first sign of symptoms. Takes care of it everytime.

I would recommend trying D-mannose for UTI. 60 year old male, recent UTI became quite painful. D-mannose every two hours, normal dose on bottle and within hours noticeable relief. Whenever symptoms recurred since then a day or so of D-mannose twice a day abates the symptoms. Bear in mind that it only helps with Escherichia coli (E. coli) infections, which are the majority of UTI infections.

Best thing is no side-effects that I noticed. It is best to not take high doses for an extended time, to protect the kidneys or if you are prone to diabetes (see webmd.com). The body does not metabolize much of D-mannose so it passes out through the urine, taking the E. coli with it.

MY mother suffered from recurrent UTIs until she started using D Mannose. It stopped her infections and relieved her from the yeast infections that the antibiotic regimen seemed to always inflict.

ellura (36 mg PAC DMAC) is far and away the best product to prevent recurrent UTIs. It is a medicine in France but is a supplement in the U.S. It is made from the active ingredient of the cranberry, the A-type Proanthocyanidin, found in the juice. ellura definitely a GREAT product!
