Is D-Mannose safe for children?

Unlike medications such as antibiotics which are classed as chemical substances, D-Mannose is a completely natural simple sugar classed as a food supplement. D-Mannose is not metabolized (not processed by chemical reaction), rather its simply passed through the urinary system, making it safe to use for children as well as diabetics. For young children and infants, the dose should be adjusted according to weight. Consider the powdered version, or smaller, easier to swallow 500mg tablets.

Is D-Mannose safe during pregnancy?

D-Mannose will cross the placental barrier, but is most unlikely to cause any damage to the fetus, just as a spoonful of regular table sugar would not. Research shows that the fetus needs D-Mannose for normal development. If you have any concerns, we recommend that you consult a medical professional who knows you and your circumstances.

An NIH Randomized Clinical Trial has demonstrated a 2 gram daily dose of pure D-Mannose prevented recurrence of acute cystitis in 85.4% of women with a history of recurrent UTI.

D-Mannose and Catheterisation

The D-Mannose dose for catheterised people, men or women, generally needs to be higher than the dose for people who do not catheterise. The actual amount you need to take is best found by trial and error. Begin with the recommended adult or child dose, and gradually increase daily if necessary.

Is D-Mannose safe to take with Cranberry?

Persons with confirmed bacteriuria, should avoid cranberry and cranberry products which are thought to considerably increase the chances of the infection recurring with increasing severity. Cranberry juice contains ascorbic acid which acidifies the urine, creating an environment in which gram negative bacteria, such as E. coli, thrive. It is also high in sugar which can promote the growth of bacteria. Alkalising the urine may help prevent bacterial growth.

Which foods contain D-Mannose?

Our D-Mannose is from extracted from sweet forest timbers (mainly of the hard Fagaceae and Betulaceae families) without the use of solvents. D-Mannose is also naturally occurring in trace amounts in many fruits (berries, tomatoes, apples, oranges, peaches, pineapples), vegetables (bringle, green beans, cabbage, broccoli), legumes (kidney beans, green beans, soybean, lima beans) and spices. Although it is also found in cranberries, the ascorbic acid in cranberries acidifies the urine, creating an environment in which E. coli thrive. Long term, eating fruit and vegetables promotes good health, however the amount of D-Mannose found in food is substantially less than what would be required for immediate bladder support.

The Cranberry Juice Cystitis Myth

Does D-Mannose make you gain weight?

When ingested, D-Mannose is absorbed directly into the blood from the upper gastrointestinal tract. Unlike glucose, D-Mannose is not converted to glycogen, nor stored in the liver. It is metabolised eight times slower than glucose, making it a low GI supplement, which helps metabolise fat more efficiently. Within four hours, ingested D-Mannose has been entirely filtered out of the blood by the kidneys and is stored in the urinary bladder. It is now ready to be expelled from the body via urine, leaving no chance for weight gain from D-Mannose itself.

What causes Cystitis in Cats and Dogs?

The vast majority of Feline cystitis and Canine cystitis, as in Humans, is caused by the E. coli strain of bacteria. And as with humans, cystitis (inflammation of the bladder) and Urinary Tract Infection is more prevalent in both female cats and dogs, than in males. Cat Cystitis is sometimes referred to as "Crystals" because of the appearance of microscopic crystal like particles that form in the urine. If left untreated, the crystals can develop into life-threatening bladder stones. An alkalising diet will help maintain alkaline urine which is believed to help prevent the formation of crystals.

How to test your pets for cystitis

Testing your cat's or dog's urine for the presence of blood, leukocytes, and nitrites can be done at home with regular UTI test strips. Significant amounts of blood, leukocytes, and nitrites in the urine is a very strong indicator of urinary tract infection, inflammation of the urinary bladder, or cystitis, all of which can be usually treated with DMannose Pet.

What's the best way to feed D-Mannose to my pets?

First try simply adding it to their water supply. It has a mildly sweet taste and many pets have a liking for it. If that fails, try adding to their favorite drink, if they have one, or sprinkling the powder onto their food.

Will I still need to see a Veterinarian for my pet's UTI?

Many of customers have reported no longer needing to visit their Vets after commencing treatment for their pet's UTIs with D-Mannose, saving both time and money. If you do not see an improvement in your Pet's UTI symptoms within 24 - 48 hours, seek Veterinary advice.
