A number of small studies have suggested that D-mannose may help keep E. A study published in the World Journal of Urology in examined the use of D-mannose to prevent recurrent, or returning, urinary tract infections. After one week of initial treatment with antibiotics for a UTI, women with a history of recurrent UTIs took either D-mannose powder, the antibiotic nitrofurantoin , or nothing for six months. During the six-month period, the rate of recurrent UTIs was significantly higher in women who took nothing compared to those who took D-mannose or the antibiotic.
The study concluded that the risk of recurrence was the same for the supplement group as the antibiotic group. Plus, fewer side effects were reported with D-mannose compared to the antibiotic. A small study of 43 women published in found that D-mannose taken twice daily for three days during an infection followed by once a day for 10 days resulted in a significant improvement in symptoms, UTI resolution, and quality of life. Those who received D-mannose for six months following treatment had a lower rate of recurrence than those who took nothing.
Although D-mannose shows promise in these preliminary studies, a review published in concluded that there is a lack of strong evidence that D-mannose—and other remedies like cranberry juice and vitamin C —should be used as a replacement for antibiotics in treating UTIs.
Research is ongoing and more studies are needed. Preliminary research suggests that taking D-mannose may help prevent or treat UTIs in those with recurrent infections. However, studies are not large enough to support using D-mannose as a replacement for antibiotics. Common side effects of D-mannose include bloating, loose stools, and diarrhea.
As D-mannose exits the body in urine, there is also some concern that high doses may injure or impair the kidneys. Since D-mannose can alter your blood sugar levels, it's crucial for people with diabetes to take caution when using D-mannose supplements. Not enough is known about the safety of the supplement during pregnancy or breastfeeding, so it should be avoided.
Children shouldn't take D-mannose as well. As a rule, self-treating a UTI with D-mannose, or avoiding or delaying standard care, is unadvised as it can lead to serious complications, including a kidney infection and even permanent kidney damage. D-mannose supplements may cause bloating or loose stools and can alter blood sugar levels.
At high doses, there may be serious risks such as kidney damage. Little is known about the long-term safety of D-mannose or at what dose the supplement may be considered harmful or toxic. While D-mannose is typically considered safe because it occurs naturally in many foods, doses higher than what is consumed through normal diets may pose unknown health problems; it's simply not known at this stage.
The optimal dosage of D-mannose and its long-term safety are still largely unknown. The amount taken in studies to prevent UTIs was up to 2 grams daily. Since then, journals have published some small studies, and researchers are currently conducting larger, more rigorous studies.
A study in the World Journal of Urology found that D-mannose may be effective in preventing people from getting further UTIs after they have recovered from one. In the study, D-mannose was slightly more effective than the antibiotic Nitrofurantoin.
However, the study participants knew whether they were taking D-mannose or not. This awareness might have affected their perception of how effective it was. A pilot study found evidence to indicate that D-mannose may be an effective treatment for UTIs and could also prevent them.
However, the authors noted the need for further research to confirm this. They plan for the study to involve women, half of whom will receive D-mannose supplements, while the other half will receive a placebo. The study will conclude in and may provide more insight into how D-mannose affects UTIs. More studies are necessary to determine whether or not D-mannose is a useful treatment for UTIs.
Without these studies, it is not clear what the dosage of D-mannose should be or whether it may interact with other medications or cause side effects. In one study , the only side effect that some of the participants taking D-mannose supplements experienced was diarrhea. However, researchers noted that the diarrhea was not severe enough for them to stop taking the supplements. Another article suggested that taking D-mannose supplements may cause complications for women who are pregnant or have diabetes.
Due to the lack of research to date, it is difficult to determine either the right dosage of D-mannose or the form that people should take it in. It is likely that the correct dosage for treating an active UTI will differ from that for preventing UTIs from recurring. In one study , participants who had received initial antibiotic treatment for a UTI drank 2 grams of D-mannose powder dissolved in water each day for 6 months.
About 80 to 90 percent of UTIs are caused by escherichia coli a. However, UTIs can also be caused by other bacteria or fungi. You may have heard about D-mannose for treating UTIs. D-mannose is a carbohydrate. D-mannose is found in foods such as:. You can also find D-mannose in dietary supplements.
Some supplements add other ingredients such as cranberry powder. There it attaches to e. And if e. Instead, eventually our body eliminates the D-mannose and e. Considering how it works, it seems like taking D-mannose would be a great way to prevent UTIs or treat them.
In a study , researchers examined women with recurrent urinary tract infections. The D-mannose group experienced the same reduction in risk of UTI as the antibiotic treatment group did. In a pilot study of 43 adult women with UTI or symptoms of a bladder infection. These women took oral D-mannose twice daily for three days and then once a day for 10 days. After this, they checked their symptoms and tested for bacteria in the urine called bacteriuria. Most reported improved symptoms and only one woman who took D-mannose had another UTI during that time.
Two systematic reviews published in each examined clinical trials on the use of D-mannose to help prevent recurrent urinary tract infections. D-Mannose is a popular supplement for those looking for a natural solution to manage UTIs scroll down the page to read comments from the readers like you!
