Product Introduction:

D-mannose powder is a monosaccharide, a component of a variety of polysaccharides, and a sugar related to glucose. Like glucose, it can be naturally produced in the body and exists in the form of starch in some plants.

Several fruits and vegetables contain mannose, including cranberries, apples, oranges, peaches, broccoli, green beans, etc. Mannose is also present in some nutritional supplements and is provided in capsule or powder form.

D-mannose powder is very important in human metabolism. It is widely distributed in body fluids and tissues, especially in the nerves, skin, testicles, retina, liver and intestines. It is directly used to synthesize glycoproteins.

Chemical properties of d-mannose:

There are two types of D-mannose powder: α-type and β-type. Α-form is a methyl crystal with a melting point of 133°C; β-form is an ethyl crystal with a melting point of 132°C (decomposition point). Sweet taste, slightly bitter aftertaste. It is easily soluble in water (250%), hardly soluble in ethanol (0.4%), and insoluble in ether.

In plants, it mainly exists in polysaccharides such as mannan in the form of condensates. The free form is present in the exudate of the coconut husk and Fraxinusornus (Fraxinusornus). In addition, there are traces in citrus peel, germinated seeds and molasses.


  • D-mannose powder is a carbohydrate that plays an important role in the glycosylation of molecules in various cellular processes.
  • It involves the N and O glycosylation of bovine protein products used in infant formula milk powder. It is also responsible for the O-glycosylation of the helper T cell-derived cytokine interlukin-17A (an important cell signaling molecule).
  • Used in cell culture and molecular biology.
  • Used as a sweetener in biochemical reagents.

Are there any side effects of D-mannose?

D-Mannose Powder is generally considered safe because it is naturally present in many foods. However, it is easy to cause some undesirable symptoms when overdose

  1. Excessive mannose may cause diarrhea, loose stools and abdominal distension, and excessively high doses may harm the kidneys.
  2. There is still too little literature on the use of mannose during pregnancy and breastfeeding. Before the experimental safety data supports it, pregnant women and breastfeeding women should avoid using supplements as much as possible.
  3. Some studies have shown that mannose may make blood sugar control more difficult for diabetic patients.

If you are considering using mannose to treat urinary tract infections or use it for preventive purposes, please discuss with your doctor first to weigh the pros and cons
