Xylose (D-Xylose sugar supplement) (D-Xylose) — Uses, Dosage, Side Effects & Safety

Drug class: Diagnostics, Procedures & Systems

Overview

Xylose (D-Xylose) is a naturally occurring sugar used primarily as a diagnostic agent to assess the absorption capacity of the small intestine. It is not metabolized extensively by the body, making it useful for evaluating malabsorption syndromes such as celiac disease or chronic pancreatitis. When taken by mouth, D-xylose is absorbed in the small intestine and excreted in the urine. Measuring the amount of xylose in urine or blood after ingestion helps healthcare providers determine if the intestines are properly absorbing nutrients. Xylose may also be used as a nutritional supplement in rare metabolic conditions. Key points: Xylose is generally well tolerated, but should only be used under medical supervision, especially in children or those with kidney problems. Always follow your healthcare provider’s instructions for preparation and testing.
