Yup, not cranberry as we’ve been made to believe. D-Mannose is a naturally occurring sugar that is found in fruits like cranberry and blueberry, and that’s why cranberry juice and capsules are often suggested for the treatment of UTI’s.
What’s great about D-Mannose is it’s absorbed by your body slowly, so it won’t interfere with your blood sugar, even if you’re diabetic or have insulin dysregulation. And, even in high amounts it doesn’t cause any adverse side effects.
How does D-Mannose work?
Most UTI’s are caused by E. Coli bacteria. D-Mannose works by attaching to the E. Coli, which causes them to stick to each other and prevents them from sticking to the walls of the urinary tract.  Think of it like a lint roller for the bacteria in your urinary tract!
In addition to taking it when you have a UTI, you can also take it when you feel you are most prone to getting UTI’s – like when you are taking antibiotics or having lots of sex (the latter being the preferable scenario!)
How to take D-Mannose:
- I recommend UT Vibrance if you can find it near you. Follow the dosage instructions on the label.
- You can also buy D-Mannose powder or capsules. The recommended dose is:
- 1000-2000mg taken every 3-4 hours for 7 days for acute infections. Symptoms should subside in about 1-2 days but it’s important to keep taking it.
- 500mg-1000mg taken once a day to put an end to chronic/recurring infections.
- 1000mg before sex and then 1000mg after sex, to prevent UTI’s caused by intercourse.
Other natural solutions for UTI’s:
Here’s something you should know – D-Mannose doesn’t work for everyone because it is only effective against E. Coli bacteria, which accounts for 90% of UTI’s.
My dear friend who inspired this post is actually part of the remaining 10%. D-Mannose didn’t totally work for her because her chronic UTI’s were likely linked to another type of bacteria and/or what is known as a biofilm. We’ll get to that in a moment.
Lauricidin for UTI’s
First, you might want to try something called Lauricidin, which is a product that is very helpful for women who have bacteria that are not E.Coli, and are not responding to D-Mannose treatment. These bacteria are known as gram positive bacteria, whereas E. Coli is known as gram negative bacteria. Gram positive bacteria families include, Streptococcus, Staphylococcus, Corynebacterium, Listeria, Bacillus, and Clostridium.
How does Lauricidin work?
Lauricidin contains monolaurin, which is a medium chain fatty acid derived from coconut oil that is anti-viral, anti-fungal and antibacterial. Monolaurin is actually found in breast milk, and it provides immune support to babies.
Unlike antibiotics, it specifically targets pathogenic bacteria so it won’t mess with beneficial bacteria, which is a major deal. Lauricidin will disrupt the cell membranes of these gram positive bacteria, which blocks their ability to replicate, so the immune system can get in there and destroy them. 
How to take Lauricidin:
According to the label instructions, simply place the mini-pellets in your mouth and swallow with cool liquid. Intake levels vary from 1/4 tsp. to one full tsp. two to three times a day with food. You can purchase Lauricidin here and you can learn more about it here.
Biofilms and UTI’s:
A biofilm is an accumulation of various species of bacteria along the surface of the urinary tract and bladder, that has the ability to survive even in unfavorable conditions. When I think of it, I picture a basketweave pattern that is strong and unbreakable.
Not only does this seemingly impenetrable wall of bacteria make it difficult to treat UTI’s, it also makes them come back over and over again because the biofilm does not go down easy. I know, every woman’s worst nightmare.
How to get rid of biofilms
There is a solution to biofilm growth known as a biofilm disruptor.
How does a biofilm disruptor work?
A biofilm disruptor is exactly as it sounds. It contains enzymes that break down and dislodge the complex structure of the biofilm, thus improving the chances of getting rid of the UTI once and for all, and reducing their recurrence. I think of those ads for Dawn dish soap where it literally breaks through a wall of grease. HA!
Best Biofilm disrupters for UTI’s
I recommend Klaire Labs Interfase Plus, which you can buy here. You should follow the dosage instructions on the label. You can read more about this amazing product here. You can also check out Biofilm Defense as an alternative to Interfase Plus.
You should use either the Interfase Plus or the Biofilm Defense in conjunction with D-Mannose or Lauricidin, to really knock the infection out.
