D-mannose

English name pending

D-mannose is a monosaccharide. After it enters the body, most of it reaches urine unchanged via the kidney, occupying mannose-binding sites on Escherichia coli fimbriae and supporting uroepithelial comfort.

01

Why supplement?

✓

Reduce urinary-tract bacterial adhesion

Mannose's stereochemistry matches the binding protein of E. coli type 1 fimbriae. Free mannose in urine occupies these sites first, so bacteria have a harder time sticking to bladder epithelium. People with repeated frequency and burning usually feel this as lower-urinary-tract comfort.

✓

Support glycoprotein glycan assembly

After phosphomannose isomerization, mannose can enter N-glycans of glycoproteins; cell-surface glycocalyx assembly uses this hexose. Congenital glycosylation research discusses it; everyday supplementation is still most often asked about as occupancy on urinary epithelium.
