Product Introduction

D-Mannose is a simple sugar (monosaccharide) that occurs naturally in various fruits and vegetables, including cranberries, apples, peaches, and blueberries. It is chemically similar to glucose but is metabolized differently in the human body.
It is quickly excreted by the kidneys into the urine, where it helps maintain urinary tract health by preventing certain bacteria from adhering to the bladder wall.

D-Mannose is widely used as a dietary supplement for urinary tract support and is considered safe even for long-term use.
