We explored how D-mannose could help prevent urinary tract infections and discomfort in patients undergoing cystoscopy. In a well-structured study with 32 patients, those receiving D-mannose experienced significantly fewer UTIs and less severe urinary symptoms compared to those who did not receive treatment.
While the treatment showed promise by reducing the number of infections and pain, no major difference was found in overall quality of life scores between the groups. This indicates D-mannose could be beneficial for specific discomforts related to the procedure.

Yeast impacts sperm quality negatively
Yeast and Fertility: Effects of Activity of spp. on Sperm Quality.
We examined how certain yeast strains affect male fertility, particularly by observing their influence on sperm quality.
Our research revealed that these yeast strains altered conventional sperm parameters like viability and motility when incubated together.
Interestingly, while functional parameters showed changes, these were not statistically significant. However, pretreating sperm with mannose did reduce the impact of the yeast, suggesting that the yeast's interaction with sperm is likely mediated through mannose receptors.

D-mannose has limited preventive effects
[Recurrent cystisis: No medicine preventive means].
We considered how D-mannose and other lifestyle changes might help prevent recurrent urinary tract infections. Our review looked into various preventative measures, including hygiene and diet.
We found that D-mannose can potentially help by preventing harmful bacteria from sticking to the urinary tract. However, its effectiveness may vary based on the dosage. While these methods are generally well-tolerated, they are not guaranteed solutions.
We concluded that a mix of dietary adjustments and proper hydration could serve as an alternative to long-term antibiotic treatment.

An AMAZING product! I endured chronic bladder infections for almost five years, trying numerous antibiotics and alternative treatments. Then, someone recommended D-Mannose, and I thought "why not?" I bought it, and within hours, my symptoms vanished. I'm now free from infections, antibiotics, and yeast infection. D-Mannose is fantastic; I wish I'd known about it five years ago.

Excellent! No more UTIs thanks to D-Mannose. Unlike many products filled with additives, this is purely D-Mannose, and it's organic. It dissolves quickly in water and tastes great. After using it for a year while managing an indwelling catheter, I haven't had a single infection. I simply mix one teaspoon in water daily. It's 100% effective—no more antibiotics for me!

D-Mannose spared my four-year-old daughter from long-term antibiotic use for chronic bladder infections. We’d visited the emergency room frequently, but opting for D-Mannose instead of antibiotics proved beneficial. It detaches e-coli from the bladder wall, allowing her to flush out the pathogens. A daily teaspoon kept her infection-free for extended periods, and she hasn’t needed antibiotics for over a year!

This product has been a game-changer for my uncle! He is quadriplegic and had been on antibiotics for years due to UTIs, depleting his good bacteria and making him increasingly ill. After starting D-Mannose, he was a changed person within a week. We just ordered two more bottles to ensure we never run out. He has not had a single infection since and is now antibiotic-free since January. He is so much more comfortable and happier, with noticeable weight gain. Our whole family is ecstatic! Highly recommend!

After enduring chronic yeast infections, I began taking one teaspoon of D-Mannose powder daily. I managed to go an entire year without any infections until I forgot it on a trip and developed a yeast infection swiftly afterwards.
A yeast infection, also known as candidiasis, is a common fungal infection caused primarily by an overgrowth of the Candida species, with Candida albicans being the most widespread culprit. These infections typically occur in warm, moist areas of the body, such as the vaginal area, mouth (oral thrush), and skin folds. While yeast is normally present in small amounts in the body, factors like antibiotics, hormonal changes, or a weakened immune system can lead to an imbalance, causing the yeast to multiply excessively and result in uncomfortable symptoms.
In women, a vaginal yeast infection can cause symptoms including itching, burning, and discharge that resembles cottage cheese. It's worth noting that yeast infections are not considered sexually transmitted infections, but sexual activity can sometimes exacerbate the symptoms. Treatment often includes antifungal creams or oral medications, which are usually effective in alleviating the symptoms and clearing the infection. If you suspect you have a yeast infection, it's best to consult with a healthcare provider to confirm the diagnosis and discuss appropriate treatment options.
D-mannose is a type of simple sugar that is closely related to glucose. It is naturally found in various fruits and plants, including cranberries, apples, and peaches. D-mannose has garnered attention primarily for its potential benefits in supporting urinary tract health. Research suggests that it may help prevent urinary tract infections (UTIs) by inhibiting the adhesion of bacteria, such as E. coli, to the walls of the urinary tract.
Many people consider D-mannose as a natural supplement to support urinary tract function, particularly for those who experience recurrent UTIs. Available in powder or capsule form, it is often taken for preventative purposes or during an active infection, thanks to its ability to promote urinary health. While more research is needed to fully establish its efficacy, D-mannose is generally regarded as safe for most individuals, albeit it’s always a good practice to consult with a healthcare professional before beginning any new supplement regimen.
D-mannose, a simple sugar often touted for its ability to prevent urinary tract infections, does not specifically target yeast infections. Yeast infections are typically caused by an overgrowth of Candida, a type of fungus, and while D-mannose can inhibit the adherence of certain bacteria to the urinary tract, its effects on yeast are not well-established in scientific literature.
If you are dealing with a yeast infection, conventional antifungal treatments—such as topical creams or oral medications—are the most effective approaches. However, incorporating D-mannose into your routine may support overall urinary health, but it's not a substitute for antifungal therapy. Always consult a healthcare professional for advice tailored to your specific situation and for optimal treatment of yeast infections.
Based on user reviews, the time it typically takes to see results from D-Mannose can vary, but many users report noticeable improvements relatively quickly. For example, one user mentioned they experienced relief within half a day and saw the infection disappear after two days of taking D-Mannose at a dosage of 9 grams per day Read Review. Other reviews indicate that some users found their symptoms alleviated within a week Read Review.
Several users have also reported that maintaining a daily dosage of D-Mannose resulted in longer-term relief, with some stating they have not experienced symptoms for over a year Read Review. However, it is essential to note that individual experiences may differ, and results can hinge on various factors, including the severity of the infection and each person's unique body chemistry.
Based on user reviews, many people have reported significant improvements in their symptoms after using D-Mannose. Users highlight that they have experienced relief from chronic bladder infections and UTIs, often after just a few days of use. For instance, one reviewer shared that after just a day of taking D-Mannose, their symptoms vanished, allowing them to avoid antibiotics altogether Read Review. Another user noted that after a year of consistent use, they hadn't had an infection or needed antibiotics, which underscores the product's potential effectiveness Read Review.
Additionally, caregivers reported similar success stories, such as a mother who found D-Mannose effective for her daughter, thus eliminating the need for long-term antibiotic treatments Read Review. Some users also appreciated D-Mannose for managing yeast infections, stating an end to their long-standing battles with such conditions, even after unsuccessful attempts with antibiotics Read Review. However, it's essential to note that individual experiences may vary; results can be influenced by the severity of the condition and each person's unique body chemistry.
Based on user reviews, many individuals found D-Mannose to be effective when combined with other supplements for addressing yeast infections. Users frequently reported significant relief from chronic yeast infections after integrating D-Mannose into their regimen. For example, one user mentioned that after taking D-Mannose daily for a year, they managed to overcome long-standing yeast infections, which they had previously battled with little success using antibiotics Read Review. Another user indicated that D-Mannose proved to be a better alternative to antibiotics, effectively preventing recurrent yeast infections for over a year Read Review.
Some users noted the effectiveness of D-Mannose in conjunction with other natural remedies, suggesting it as a supportive measure rather than the sole solution. A reviewer experiencing chronic infections stated they started taking D-Mannose daily, which successfully led to a year without infections even after years of treatment failures Read Review. This highlights that while D-Mannose has presented success stories alone, those interested in a multi-faceted approach may benefit from considering it alongside other natural therapies.
Based on user reviews, the most frequently reported dose for D-Mannose when treating yeast infections appears to be one teaspoon daily. Several users have mentioned that taking this amount consistently helped them go long periods without infections, with one reviewer stating, "After enduring chronic yeast infections, I began taking one teaspoon of D-Mannose powder daily. I managed to go an entire year without any infections until I forgot it on a trip" Read Review. Another user noted that after trying D-Mannose daily for two months, they haven't experienced a yeast infection in over a year Read Review.
In some cases, users have reported taking higher amounts, such as 9 grams per day, to achieve quicker relief, as evidenced by one review stating, "After taking 9 grams per day, I found relief after half a day, and after two days, the infection disappeared without antibiotics" Read Review. Overall, while individual experiences may vary, starting with a teaspoon daily seems to be a common recommendation among users for managing yeast infections.

This product works! I had no complaints — everything is as promised and even better. After taking 9 grams per day, I found relief after half a day, and after two days, the infection disappeared without antibiotics. I plan to continue using it but at a reduced dose and will order more!

As a long-term sufferer of yeast infections, I have tried nearly everything available, including two surgeries. Upon reading about D-Mannose powder and with my doctor's advice, I started it a year ago, and I have not experienced any symptoms of those painful infections since. Thank you, iHerb, for the great savings on your Now Foods D-Mannose powder!

I had frequent visits to the doctor for chronic yeast infections and even a kidney infection from one. After trying various antibiotics without success, I tried D-Mannose daily for two months and now only take it if I suspect a yeast infection is starting. I haven't had one in over a year! This product is simply the best. Thank you so much! Highly recommend!
