D-mannose is a naturally occurring, simple sugar found in fruits like cranberries and pineapples that stops bacteria from sticking to body tissues. As it is absorbed from the gastrointestinal tract, unlike many sugars, it is not converted into glycogen or stored in the liver. Because of this, D-mannose doesn’t affect blood sugar levels, which makes it safe for everyone, including diabetics. Once D-mannose is absorbed, it is quickly filtered out of your system by the kidneys and then flushed out of the body in the urine. In the process, the sugar dislodges bacteria present in the kidneys, bladder, and urethra. Studies suggest that Mannose may maintain and support a healthy urinary tract by blocking the adhesion of disease causing organisms like E. coli to the surface of the host tissue. A dose of 2 grams taken every two to three hours may resolve issues such as vaginal and urinary tract infections caused by E. coli in a few days, without the complications of antibiotics that can kill the body’s beneficial bacterial flora.
