Xylotene What is D-xylose

What is D-xylose?

Sugar D-xylose: What is it, what's it used for?

D-xylose, also taking its name from the Greek word Xylo meaing wood, has 100% of the sweetness of regular table sugar (sucrose) but only 2.4 calories per gram. It is one of eight sugars (fucose, galactose, glucose, mannose, n-acetylgalactosamine, n-acetyl glucosamine, n-acetylneuraminic acid, and xylose) associated with glycoproteins and considered essential for human health. When these glyconutrients combine with proteins, they produce glycoproteins, vital for the immune system amongst other functions.


At a minimum of 2.4 calories per gram, Xylose contains about 40% less calories than regular table sugar which contains 3.87 calories per gram. With a sweetness equal to sucrose, and a lower impact on blood sugar and insulin secretion, Xylose is widely used as a healthier alternative by diabetics. Both xylose and xylitol have important uses as sweeteners for diabetics. Despite Xylose being a stereoisomer of glucose, only glucose provokes an insulin response, and thus ingestion of xylose as a substitute has obvious benefits. Diabetics: Watch your blood-sugar levels and use within your dietary allowances if known.

Foods containing D-xylose

D-xylose can be found in fruits, cereals, bread, coconut shells and vegetables like corn, potato, peas and carrots.

Medical Uses

A D-xylose absorption test is a procedure used to diagnose malabsorption, or how well the small intestine absorbs simple sugars. D-xylose is normally easily absorbed by the intestines. A few hours after being ingested, a measure of the level of Xylose in the blood or urine is taken to evaluate the patient's ability to absorb carbohydrates.

Swedish researchers have looked at decorin, a xylose-linked glycoprotein in collagen, and studied its absence in relation to osteoarthritis.

Side Effects

National health agencies across Europe and the Americas have concluded D-Xylose is safe and effective when used as a food supplement. When consumed in excessive amounts, at a rate many times the suggested maximum dose, it may cause adverse effects such as gastrointestinal discomfort and diarrhea. A tolerance for larger amounts can be developed over time. Always consult your health care practitioner before taking any food supplements.

Candida sufferers: Xylotene is thought to inhibit candida growth but encourage the growth of some wheat fungi.

Xylotene, like Chocolate, should never be given to dogs or any animals.
