What Is D-Mannose?
D-Mannose, also known as mannose, is a simple sugar with the chemical name C6H12O6. It is classified as a monosaccharide and typically appears as a white crystalline powder. D-Mannose is naturally found in fruits like cranberries, apples, and peaches. It can also be synthesised from glucose through a series of chemical reactions. In the body, D-Mannose is absorbed more slowly than glucose and is not stored as glycogen, which means it is excreted in urine. It is often used in supplements to support urinary tract health by helping to flush out bacteria.
How It Works In The Body
D-Mannose is a type of sugar that the body uses to help maintain urinary tract health. It works by attaching to certain bacteria (like E. coli) in the urinary tract, preventing them from sticking to the walls and allowing them to be flushed out during urination. This helps contribute to normal urinary tract function.
