D-Mannose helps prevent and treat UTIs caused by E. coli bacteria.
Keep in mind, E. coli are responsible for 90% of all urinary tract infections.
Sounds great! But what’s D-Mannose? And what D-Mannose dose is good for treatment and prevention of UTI?
While D-Mannose is a great supplement, but it’s only one part of the solution.
Do you want to prevent UTI naturally, without antibiotics?
Most likely you’ll need a range of strategies to:
- Decrease bladder inflammation
- Fight bacterial biofilms
- Decrease number of pathogenic bacteria (this is where D-mannose could be handy)
- And implement healthy lifestyle changes.
D-Mannose is actually a type of sugar. But not your regular sugar (glucose), which goes with your coffee (this type would actually make your symptoms worse).
Your body does not metabolize D-Mannose like other sugars. That’s why D-Mannose does not affect the blood sugar levels, and therefore is safe for the diabetics.
This is also why once you intake D-Mannose it is quickly expelled from your body in urine.
High concentration of D-Mannose in urine is the main reason why it works against E. coli bacteria in your bladder.
#1 Common mistake: drinking your first dose of D-Mannose with a lot of water
If you just ingested D-Mannose, pause and wait before drinking a lot of water. If you are drinking too much water right away, you are diluting the concentration of D-Mannose in your bladder.
Here is how you do it:
- Take your dose with no more than half of a glass of water.
- Then wait for about 45 mins to an hour.
- After that, drink plenty of water in order to get rid of harmful bacteria.
This way concentrated D-Mannose has more time to bind to E. coli bacteria before you flush them with water.
#2 Pricey mistake: buying D-Mannose in capsules
Do not overpay for buying capsules.
You can measure D-Mannose powder with a teaspoon: don’t worry, you do not have to be precise.
The powder has pleasant sweet taste and when you add D-Mannose to water it dissolves easily.
If you buy D-Mannose in capsules, you are not only wasting your money but also ingesting all extra ingredients that are required for processing the powder into capsules (for example rice flour, stearic acid, magnesium stearate and silica).
#3 Dangerous mistake: waiting too long before seeing a doctor
If you decided to treat your UTI with D-Mannose you are assuming certain health risks.
Therefore, if your symptoms have not diminished or completely disappeared after 1-2 days, do not wait any longer and go to the doctor.
Remember, D-Mannose only works for UTIs caused by E. coli bacteria, and if you let your infection go untreated you are at risk of developing a kidney infection, or even a deadly sepsis.
If you are experiencing frequent UTIs, there is a higher chance that your infection is caused by multiple bacteria types, not only E.coli.
Scientists still don’t know why for some D-Mannose is a miracle cure, but for other patients who as well have a UTI caused by E.coli, D-Mannose simply doesn’t work.
It’s a natural product and it’s possible that variations in sources and methods of manufacture, as well as a diversity of pathogenic bacteria, could play a role.
#4 Taking D-Mannose too late
It appears that D-Mannose works best if taken preventively or at the very first signs of infection.
A full-blown UTI might benefit from D-Mannose supplementation, but you are running a risk that bacteria are growing at a faster rate than you are able to clear them.
If you end up taking antibiotics, supplementing with D-Mannose could be an option to speed up recovery, but do not stop your antibiotic treatment to switch to D-Mannose, you’ll be running a risk to develop a drug-resistant bacteria.
#5 Relying only on D-Mannose for your UTI treatment strategy
I understand your desire to stick with a natural supplementation for your UTI prevention and treatment needs.
However, UTIs (especially chronic ones) are a multi-faucet problem requiring a complex approach.
Thankfully, there are plenty of herbal and natural remedies to help you stay healthy.
If this is your first UTI, don’t wait for it to turn into a chronic problem. Contracting a UTI might be a warning signal from your body about other imbalances (vaginal flora, hormones, stones etc..).
#6 Buying D-Mannose made from corn if you are allergic to corn
Did you know that most of the D-Mannose products are made from corn? If you are allergic to corn, your reaction might be similarly upsetting when you take D-Mannose (hives, GA troubles).
If you know or suspect that you might be allergic to corn, choose D-Mannose made from cranberries and pineapple.
D-Mannose Dose For An Acute Infection
Consider this when trying to supplement your UTI treatment with D-mannose:
- Try the typical D-Mannose dose for UTI treatment: 1500-2000 mg (capsule form) or one-half to one teaspoon (powder) in a half glass of water every two to three hours for five days.
- Drink plenty of water in between D-Mannose doses.
- Remember that nobody has yet clinically tested and established the exact quantity and frequency of D-Mannose for UTI treatment.
- Different people will react differently to the same D-Mannose dose (depending on their age, weight, overall health).
- Quality and purity of D-Mannose could vary from one manufacturing company to another, and even from one batch to another!
- D-Mannose has certain side-effects and it’s important to weigh all pros and cons before you try it.
- Be careful which D-Mannose brand you chose if you are allergic to corn
- Once you have started taking D-Mannose, UTI symptoms should significantly diminish within the first 48 hours, but keep it up for 2-3 more days even if the symptoms are gone. If your symptoms did not diminish within the first day, see a doctor immediately.
- Normally, one 50g dose (2-3 ounces) of D-Mannose is sufficient (most likely that’s how much you’d have in one package) for one course.
- Some find it beneficial to follow up an acute episode of a UTI with a month of preventive D-Mannose dose taken daily.
- Consult with your physician on how to supplement your UTI treatment with D-Mannose.
D-Mannose Dose For UTI Prevention
I take D-Mannose after certain trigger events that could cause my UTIs.
Consider this when adding D-Mannose to your UTI prevention strategy:
- For UTI prevention take 1500-2000 mg (or one-half teaspoon) once or twice a day.
- You can take “preventive” dose safely for as long as you want. Your bacteria won’t develop a resistance.
- Take D-Mannose every time you think your vaginal flora is compromised (with the first signs of yeast infection, when consuming a lot of sugar, during stressful times, after sex, etc.).

Is D-Mannose suitable for children?
Well, it is only sugar! At the same time, the doses should be adapted according to age and weight. However, there is a rare genetic disease that messes up how mannose is produced and absorbed by your body. Make sure to educate yourself about it before treating yourself or your child.
Moreover, kids normally get UTIs because of urine retention or backward urine flow. It is important to diagnose them for the underlying issues causing the infection instead of trying to self-treat.
Definitely, do not use D-Mannose instead of antibiotics if kids are too young to report their symptoms. It is better to not experiment with any natural supplements and follow your doctor’s advice.
If your kid is already taking an antibiotic, you can try to supplement it with D-Mannose. Be extra careful with the dose to not cause diarrhea.
Is D-Mannose suitable for diabetics?
D-Mannose is most likely suitable for diabetics. Since only very small amounts of D-Mannose are metabolized by the body it won’t typically raise your sugar level.
Nonetheless, sugar levels in the blood should be monitored regularly. We still don’t know much about mannose metabolism and you should exercise caution.
How soon to expect a relief with D-Mannose?
If you started taking D-Mannose at the first signs of a UTI you would typically notice a drastic reduction in symptoms as soon as 24 to 48 hours. However, if you do not notice an improvement in your symptoms, make sure to see your physician right away.
An untreated UTI could turn into a dangerous kidney infection and even a lethal sepsis. Every time you choose to self-treat you are running a risk.
Moreover, D-Mannose supplements can also be taken for UTI prevention without damaging your natural digestive and vaginal flora, a benefit that antibiotics cannot provide.

D-Mannose and FDA: important disclaimer
D-Mannose is a popular supplement among UTI sufferers who are looking for a natural solution to prevent and treat urinary tract infections (just scroll down the page to read comments from the readers like you!).
Anecdotal evidence is growing and contributing to the Internet hype about D-Mannose products since we all want to find a cure from UTI.
However, D-Mannose is a food supplement and FDA does not regulate it. A dietary supplement product does not “diagnose, treat, cure or prevent any disease,” because only a drug can legally make such a claim. There is not enough scientific evidence that D-Mannose can treat a UTI, therefore, try it at your own risk and closely monitor your symptoms.
