D-mannose is a simple sugar produced in the body and occurring naturally in certain fruits, especially cranberries and pineapples. The adult dose of D-Mannose is more concentrated in D-mannose than these fruits or juices, and studies suggest that D-mannose is ten times more effective than cranberries.[2]
Nearly all ingested mannose gets excreted through the kidneys and into the urine.[3,4] Research suggests that lectins, present in the urinary tract and bladder, adhere to the D-mannose more readily than they do to the walls of the urinary tract. This action helps support the body’s ability to flush out these unwanted particles through the urine.[5] D-mannose users report that they can feel the effect in 24-48 hours.[6]
D-Mannose is not capable of killing either “friendly” or harmful bacteria. It simply supports the naturally protective “flushing out” mechanism of the urine.[6]
Directions
Mix 1/2 teaspoon in 2-4 oz of water 1-3 times daily, unless otherwise directed
