Is there a Simple Way to Prevent UTI’s (Urinary Tract Infections)?

Over 50% of women get a UTI during their lifetime, and for 25% of them, they keep coming back, having a significant impact on their quality of life (1,2). (Of course, UTI’s can also affect men too, although it’s about 50 times less common than in women). In this article, we are studying the latest research on how to prevent UTI’s.

What is A UTI – Urinary Tract Infection?

UTI’s are bacterial infections that can occur at any point of the Urinary Tract from the kidney to the ureter, bladder, and urethra. Infections in the Urethra are known as urethritis. And, infection in the bladder or the Ureter (the tube which carries urine from the kidney to the bladder) is commonly known as cystitis. If the bacteria reaches the kidney, it can cause a kidney infection, known medically as pyelonephritis.

Common UTI symptoms include:

  • Dysuria – pain when urinating
  • Frequent or urgent need to urinate, of often tiny amounts
  • Nocturia – frequently needing to go at night
  • Abnormal urine color usually with a strong smell
  • Haematuria or Pyuria– blood or pus in the urine
  • Lower back or abdominal pain

Although these symptoms are unpleasant, they are not considered serious, although if the infection does spread to the kidneys, it can potentially cause kidney damage or even death.

What Causes UTI’s?

Most of the time, the bacteria that cause problems in our urinary tracts come from the colon (that’s our backsides!), however sometimes in women, the bacteria can also be transferred from the vagina (1-4). Most cases of UTIs (around 80%) are caused by the bacteria E. coli (5,6,7). E. coli lives naturally in our GI system, although only in small numbers (2). However, when the growth levels of E. coli increase beyond what’s normal, and they get out of balance with the good bacteria, it can start to cause problems for us (8).

what causes UTIsE. coli have special finger-like projections called fimbriae, which are sticky and made of a glycoprotein called lectin, which allows them to stick to the cell walls of our urinary tract (9). The ends of the fimbriae are made of sticky adhesins that stick to receptors on the cells lining the urinary tract. If enough E coli can get into our urinary tracts and stick to the cells, they can multiply and colonize there, which causes an infection.

The Problem With Current UTI Treatment Options?

The standard treatment for a UTI is a course of antibiotics, and it’s been this way for many years. Antibiotics are still an effective treatment for uncomplicated UTI’s. However, the occurrence of bacterias that are causing UTI infections and are also resistant to antibiotics are growing (10). Also worryingly, even when treatment successfully cures the infection, the use of antibiotics can negatively impact other areas of our health.

The main issues are that antibiotics also kill off beneficial bacteria in our guts as well as the bad guys. Then, as the bacterial populations regrow after a course of antibiotics is over, it can cause ‘dysbiosis’. Dysbiosis is an overgrowth of potentially pathogenic bacteria, fungi, and other microbes. This can directly lead to fungal infections like thrush (both oral and vaginal), candida overgrowth, and other GI infections, most notably Clostridium difficile (11). However, Dysbiosis has also been linked with many other health conditions, including skin problems, mental health issues, immune conditions, and obesity (12).

How to Treat UTI’s Without Antibiotic?

Because of the problems with antibiotic treatment and the increase of antibiotic-resistant strains of bacteria, this form of treatment is becoming less and less effective. So going forward, the prevention of UTIs has become a significant treatment goal, especially for people who suffer from recurrent infections (13).

1st Step: Take Care of Your Hygiene to Prevent UTI’s

There are 3 major areas we can focus on to help prevent UTI’s. The first is following some basic hygiene rules to stop bacteria from the colon or vagina reaching the urethra.

They are:

  • Urinate when if you feel the need to go, and don’t resist the urge.
  • Wipe from front to back in the bathroom, so you are preventing bacteria from entering your urethra
  • Take showers instead of tub baths, and avoid hot tubs/Jacuzzis
  • If you can cleanse your genital area before and after having sexual intercourse and try to urinate as well.
  • Avoid using feminine hygiene sprays, which may irritate your urethra. Also avoid vaginal douching as this can damage the microbial balance in the vagina which can lead to an increase in pathogenic bacteria that could be transferred to the urethra, (it can also increase the chance of vaginal yeast infections and bacterial infections in the vagina.)

2nd Step: Take Live Cultures to Prevent UTI’s

The second is to take live cultures to keep the GI system healthy, restore the normal gut bacterial balance, and to make sure the E. Coli and other pathogenic bacteria are under control. Studies are showing that live cultures supplements taken orally can change not just the bacterial balance in the gut, but also in the Vagina.

There is also a close correlation between a change in the normal microbiota (i.e. bacterial balance) in the vagina and an increased likelihood of developing a UTI (14).
The microbiome of the vagina is predominantly made up of Lactobacillus strains, and studies have shown that Lactobacillus live cultures taken orally can replenish the microbiome of the vagina (15, 16).

In Finland a study showed that drinking Kefir (fermented milk containing live cultures) 3 times a week reduced UTI’s (17), another study tested live culture supplements against antibiotics for a year in a group of women who suffered from recurrent UTI’s.

They found that in women that were given antibiotics for a year, the average number of UTIs went down from 7 to 2.9 and that for women given live cultures, the average number went down from 6.8 to 3.3 (18). However, although there was a slightly larger reduction in the number of UTIs in the group of women given antibiotics, in women with ‘complicated UTI’s’ the live cultures group did better, experiencing only 3.4 recurrences as opposed to 4.4 in women taking antibiotics.

Also, rather disturbingly, the women taking antibiotics increased the amount of antibiotic-resistant E Coli that they carried to between 80% and 95% of the total amount. In contrast, the live cultures group experienced no increase in antibiotic resistance bacteria.

3rd Step: Take Cranberry Juice and D-Mannose powder

So we’ve already seen that supplementing with live cultures is virtually as effective as antibiotics for preventing UTI’s, and can reduce them by over 50% with none of the dangerous side effects of antibiotics. With proper hygiene practices, we can reduce this even more, but what if we took it another level? We can do this by also supplementing with Cranberry juice and D-mannose.

Cranberry juice has long been used as a home remedy to treat UTI’s. It was initially believed that cranberries somehow made the urine more acidic, which made it difficult for infectious bacteria to grow there (19). However, we now understand that cranberry juice works because it contains 2 compounds that stop the E Coli bacteria from being able to stick to the cells lining the urinary tract (known uroepithelial cells)(20).

D-Mannose helps with preventing UTIsThe first compound is D-mannose, which is a naturally occurring sugar. It is what’s known as mannose sensitive, and the second is a type of condensed tannin called Proanthocyanidin (or PAC for short), and it is mannose resistant. As we saw in the first image above, there are finger-like projections that come from the E Coli bacteria called fimbriae that the E. coli use to stick onto the cells on the walls of the urinary tract. They use the small sticky adhesins at the end of their fingers to do the ‘sticking.’ These adhesins are either mannose sensitive (type 1), or mannose resistant (type p).

Because D-mannose is ‘mannose sensitive’, it plugs itself in the mannose sensitive (type 1) adhesins to stop them sticking to the cells of the urinary tract walls, and because the Proanthocyanidin is ‘mannose resistant’ is can plug itself into the mannose resistant (type p) adhesins.

Although D-mannose is a component of cranberry juice, it’s recommended to take it as a separate pure D-mannose powder as this makes it 10-50 times stronger than the D-mannose in cranberry. Also, although it’s sugar it’s completely safe to take long term because very little of it is metabolized, and it doesn’t interfere with blood sugar regulation, even for diabetics (21).

Studies on the Effectiveness of Cranberry Juice and D-Mannose to Prevent UTI’s

There have been several studies showing the effectiveness of either Cranberry juice powder or pure D-mannose powder in preventing UTI’s. For example, Walker et al (22) found in their experiment that women, who were taking Cranberry Juice powder had, on average, 2.4 UTIs per year, while those taking a placebo averaged 6 UTI’s a year.

Studies on the Effectiveness of Cranberry Juice and D-Mannose to Prevent UTI’sAnother study conducted on sexually active women between 21 and 72 put 150 women into 3 groups where one group drank Cranberry juice, one took cranberry capsules, and the other took a placebo. They found 32% of the placebo group suffered 1 or more UTIs in the year, whereas 20% of the group that drank Cranberry juice suffered one or more UTI’s and only 18% of the group taking Cranberry capsules suffered 1 or more UTI (23).

A study pure D-mannose powder conducted on 308 women after they had recovered from acute cystitis gave them either D-mannose, antibiotics, or a placebo. They found that 61% of women in the placebo group developed a recurrent UTI, 20.4% in the antibiotics group developed a recurrent UTI. Still, only 14.5% of the D-mannose group developed a recurrent UTI (24).

Conclusion: Live Cultures and Cranberry Juice for UTIs

Live cultures, cranberry juice powder, and pure D-mannose powder have all shown their effectiveness at reducing UTIs. Cranberry juice powder and D-mannose are actually more effective at preventing UTIs than antibiotics, and live cultures have many health benefits outside of preventing UTI’s and are a vital part of any health regime.

At Intelligent Labs, we’ve created a specific live cultures with women in mind (although men can take it too!) that can maximize health in body and mind, and help to prevent UTI’s. We’ve combined the highest quality live cultures (patented strains produced by Dupont), with organic cranberry juice powder and pure D-mannose powder.

Also, each capsule contains the prebiotics Sunfiber® & FOS. Prebiotics are non-digestible fibers that act as food for live cultures that are essential to ensure the live cultures successfully reproduce in the gut.

Then finally, we use an Activ-Polymer™ bottle, which features an impenetrable desiccant sleeve wrapped around the live cultures, so they are virtually moisture-free to ensure the live cultures and an Oxyfree® desiccant to absorb any oxygen and remove any residual moisture from inside the bottle. This is because live cultures will degrade whenever they are exposed to moisture and oxygen, and we do our utmost to ensure the live cultures reach you in perfect condition.

*Complicated UTIs were defined as UTIs in women with functional or structural abnormalities of the urinary tract, metabolic and/or hormonal abnormalities, or impaired host responses.
