Product Information

Urinary Tract Cleanser. D-Mannose is a simple sugar that occurs naturally in some plants, including cranberries. Although small amounts of D-Mannose are metabolized by the human body, much of it is rapidly excreted in the urine. In the bladder, D-Mannose can adhere to bacterial lectins, preventing them from sticking to the lining of the bladder. Bacteria can then be flushed away during urination, thereby precluding the formation of colonies within the urinary tract. Because insubstantial amounts of D-Mannose are used by the body, it does not interfere with blood sugar regulation.

D-Mannose is a simple sugar that cures more than 90% of all urinary tract infections (most urinary tract infections are caused by E-Coli and D-Mannose is most effective on E-Coli) and, best of all, it does this without killing a single bacteria. Nearly 15 years of clinical experience has shown that D-Mannose is just as effective as antibiotics are at curing urinary tract infections. Seems to good to be true, right? An all natural simple sugar that's completely safe, highly effective, inexpensive, and available without a prescription.


The answer is found in the interaction between D-Mannose and the bacterium found in over 90% of all bladder infections, Escherichia coli ("E. coli"). No, not the infamous E.coli mutants associated with unsanitary food processing that has hospitalized and killed people. It's the normal E.coli found as part of the "normal microflora" in every intestinal tract. But even normal E.coli do not belong in the bladder and urinary tract. In these areas they multiply and become an undesirable infection.

Why doesn't the normal flow of urine from the kidneys through the urethras into the bladder and thence beyond simply carry the E.coli right along with it? What allows the E.coli to "stick" to the inner walls of the bladder and even work their way upward (like Spiderman) in some cases reaching as far as the kidneys?

The "cell walls" of each E.coli are covered with tiny fingerlike projections. The very tips of these projections are an amino acid-sugar complex, a "glycoprotein" also called a "lectin". E.coli "lectins" have the unfortunate capability of enabling the bacteria to "stick" to the inside walls of our bladders and urinary tracts, so they can't be rinsed out by urination.

Fortunately, D-Mannose "sticks" to E.coli lectins even better than E.coli lectin "sticks" to human cells. When we take a large quantity of D-Mannose, almost all of it spills into the urine through our kidneys, literally "coating" any E.coli present so they can no longer "stick" to the inside walls of the bladder and urinary tract. The E.coli are literally rinsed away with normal urination!

WARNINGS: Keep out of the reach of children.


Who can't? Because it is so effective and benign, even pregnant women who are susceptible to recurrent urinary tract infections can safely take D-Mannose as a preventative measure to ward off future attacks. D-Mannose is 100% safe for infants and young children and they will find the taste wonderful (it is sugar!). And unlike antibiotics, one can safely stop treatment in a few days. An existing infection can be cleansed in as little as 1-3 days, after which you can stop taking D-Mannose if you wish. What about people who have diabetes? Diabetics usually need to limit their intake of sugar. If you have diabetes some people do report temporary increases in blood sugar levels, but the effect is not great and never permanent, lasting only for the length of time D-Mannose is used. D-mannose is very safe, even for long term use, although most women (or the very occasional man) with single episodes of bladder or urinary tract infection will only need it for a few days at most. Although D-mannose is a simple sugar, very little of it is metabolized. It doesn’t interfere with blood sugar regulation, even for diabetics. It creates no disruption or imbalance in normal body microflora. In the less than 10% of cases where the infection is a bacteria other than E. coli, antibiotics can be started in plenty of time. (Many physicians will likely advise collecting a urine specimen for culture, if possible just before starting D-mannose, so that the bacteria can be identified as rapidly as possible in the few cases where D-mannose doesn’t work.)

Recommended Use: Normal therapeutic dosage is 1/2 tsp. daily for chronic suffers of UTIs or weekly for preventative measures. It can be mixed with juice, milk or water. However, it is easiest to just take the powder plain.

According to Dr. Jonathan V. Wright, editor of Nutrition and Healing, during an infection it is recommended to take 1/2 tsp. every 3-4 hours. If the infection is not considerably better within 24 hours, it is probably not being caused by E.coli.

For women who experience bladder infections related to intercourse, it is recommended taking 1/2 tsp. 1 hour prior to and just after intercourse.

I've been using D-Mannose Powder 100% Pure daily to prevent recurring UTI. So far so good. I haven't had a UTI in 2 months, and I used to get one after the other. D-Mannose Powder 100% Pure is amazing. If nothing else has worked and you don't want to be on antibiotics again, give it a try.

I tried this for my 2.5 year old daughters UTI. It did not work! We waited 24 hours before taking antibiotics in hopes that this D-Mannose would work, but unfortunately it did not. I am so disappointed! Not only is my daughter still in a lot a pain, but now she has to take her first ever antibiotics. =(

I just want to let everyone know that this product is a Godsend. I was very skeptical at first to try this product, even after reading all the good reviews D-Mannose had gotten all over the internet. I now am so thankful that I went ahead and tried it. I unfortunately have been one of the unlucky people plagued with UTI's every few months due to intimate relations. These infections were not only very painful but always required a trip to the Doc's office which starting taking quite a big chunk out of my pocket. The antibiotics that I was prescribed for the infection also gave me yeast infections and within a few weeks of this type of treatment the infection would return. Ever since I started using D-Mannose my UTI's have drastically reduced. When I do happen to get one now (which occurs rarely) I just take D-Mannose for a few days I am right back to normal without having to miss work for a Doc's visit or having to spend money on antibiotics. It is nice to have a cure for UTI's that is natural and won't harm the balance of your system. I wish I would have known about this stuff sooner, it would have saved me from taking quite a few rounds of antibiotics. If you are contemplating trying this product, please do. You won't regret it. You have nothing to lose.

D-Mannose has been such a blessing. I was extremely prone to UTI's after getting married last year. A friend recommended this to me, so I gave it a try. I usually take 1 teaspoon mixed with water or juice just before intercourse, then I make sure to urinate after and it flushes any bacteria right out of the urethra and bladder. I havn't had any UTI's in months.

I have Interstitial Cystitis, a chronic bladder condition and. D-Mannose Powder 100% Pure has turned my life around. I take 1 teaspoon at night before bed. If I think I'm experiencing a flare-up, I take it 4 times a day. Since I have been D-Mannose Powder 100% Pure, I no longer need to take antibiotics. NOW makes a superior and price affordable product. I recommend it to anyone experiencing Interstitial Cystitis or frequent Urinary Track Infections.

Length of Use: more than 6 months.   Benefits: at least a month.
Taste: taste great.   Taken: before i go to sleep

I have been a UTI sufferer for years and years, and I have taken D-Mannose off and on for about 2 years. I typically get an UTI after intercourse, so I try to take it before and after. Everything that I have read says it is safe for pregnant women, etc... however, I found an article that mentions birth defects that makes me extremely nervous. I also found another one today that said taking D-Mannose can also prevent you from getting pregnant if you want to become pregnant (only 1 article on this) and only found one article mentioning birth defects. All others have mentioned that is safe for diabetics, young children, and pregnant women.

I'm very prone to UTI's. D-Mannose absolutely works. In my research, I've read that it only works for 85% of cases because there are strains of bacteria that don't adhere to D-Mannose, but for me, it's been the biggest blessing. And recently, a urine test found that although I did have a urinary bacterial infection, I was able to fight it with D-Mannose. Not having to take antibiotics makes a world of difference to me - this is a great alternative.

D-Mannose has changed my life. I've had at least one UTI per month for years. Antibiotics did me in and exacerbated my constant yeast problem. Cranberry juice (pure only) worked well in a day or two, but was nasty and nauseated me. I started teaching this year and my inability to leave the classroom to use the bathroom has made the situation out of control. I've had almost constant low-grade fevers, very little energy, and irritation and pain. In desperation I decided to try D-Mannose. I ordered Solaray Yeast Cleanse as well, because I've been told that one infection affects and perpetuates the other. It's been two months now and I've had no burning, no irritation, no cramps, no blood in my urine, no discharge. I finally feel like my pelvic region is healthy and I don't have to dread every trip to the bathroom anymore. I started with two tsp per day for 3 weeks, then dropped back to one tsp per day. I think a half would be fine now. I take it first thing in the morning, on an empty stomach so it can go straight to my bladder. It has just a slightly sweet taste, so it's great in water, but I'm sure you could put it in anything without noticing it. Bottom line: If you're suffering from UTIs at all then buy it.

I have been having painful UTIs since I entered menopause, about 3 years ago. As soon as I began to feel better, another one would begin. I tried drinking cranberry juice, eating yogurt, taking cranberry extract, and of course, antibiotic after antibiotic. Nothing worked. I complained about this to a friend, and she recommended D-Mannose. I was skeptical, but googled it and found good reviews, and that it had no side effects. I figured it wouldn't do any harm. I've been on it about a month, and for the first time in 3 years, I have NO abdominal pain at all! I don't feel the need to urinate often--am sleeping through the night again. It has to be the D-Mannose. I'm a fan. I just stir a teaspoon full into the water bottle that I carry most of the time, or stir it into my morning tea. I'm using 2 teaspoons a day, and I feel the best I've felt in years! If you suffer from UTIs, try this! It's a great product!

A friend told me about D-Mannose and the relief he had attained from using it. I ordered a 50 g container and began using it according to instructions. After two weeks, my nightly visits to the bathroom dropped from five or six times to two or three. After finishing the first order, and before receiving the second batch, my problem returned. Amazingly, within three days of resuming the once-a-day use, my nightly trips had been reduced to once or twice. I'm a confirmed user, and will continue to be.
