Mannose, packaged as the nutritional supplement “d-mannose”, is a sugar monomer of the aldohexose series of carbohydrates. Mannose is a C-2 epimer of glucose. Mannose is important in human metabolism, especially in the glycosylation of certain proteins. Several congenital disorders of glycosylation are associated with mutations in enzymes involved in mannose metabolism.

Mannose is not an essential nutrient; it can be produced in the human body from glucose, or converted into glucose. Mannose provides 2-5 kilocalories per gram. Mannose is partially excreted in the urine.
