D-mannose is a type of sugar that is related to glucose but is hardly metabolized in the body. D-mannose is excreted in the urine instead. On its way through the bladder, D-mannose binds those bacteria that cause urinary tract infections and cystitis.
The annoying bacteria disappear - bound to the D-mannose - with the urine in the toilet.
D-mannose is not only a therapy component of urinary tract infections, but also a method for the prevention of recurrent cystitis - without side effects, of course.
