D-Mannose is not a drug. It’s a naturally occurring sugar, closely related to glucose and you even produce it in your body. And very importantly, it does NOT produce the metabolic stresses that fructose does because it’s more like glucose, which every cell in your body is designed to use.
Your body absorbs D-mannose much more slowly than glucose, and the D-mannose does not convert to glycogen or get stored in your liver. Only very small amounts of D-mannose are metabolized, so it doesn’t interfere with blood sugar regulation.
Most of the D-mannose is filtered through your kidneys and routed to your bladder, then quickly excreted in your urine.
D-mannose helps to nourish your healthy flora because it doesn’t affect “friendly” bacteria. It doesn’t kill any bacteria—it just renders them unable to stay in your urinary tract.
When you take antibiotics for a urinary tract infection (UTI), the good bacteria are killed along with the bad, which is why you can develop secondary yeast infections and digestive problems.
But how can a natural sugar combat a UTI?
The answer lies in how bacteria adhere to the inside of your bladder.
More than 90 percent of all UTIs are caused by Escherichia coli (E. coli), which is normally found in your intestinal tract. Problems only arise when this ordinary bacterium is present in high numbers in places where it shouldn’t be—like your urinary system.
It should be noted that this is NOT the same E. coli associated with killer outbreaks in unsanitary food processing plants—that is a mutant variety, probably created by antibiotic overuse in our country. This E. coli is typically a normal part of your gut flora and typically is accidentally transferred to the bladder through lapses in optimal hygiene.
When normal E. coli gets into your urinary tract and multiplies, you experience the usual signs and symptoms of a UTI:
