Concepts In Confidence - Mannose Magic UTI Capsules contain digestive enzymes that help flush out E-Coli bacteria present in urine. Mannose molecules collect in your urine and when E-Coli bacteria are present they hook onto the Mannose rather than the bladder wall. These bacteria are then encapsulated by Mannose Magic and upon urination are flushed away leaving a healthy urinary tract free of UTI causing bacteria.
