Xylose is a naturally occurring sugar classified as a monosaccharide. While not commonly used as a primary ingredient in performance supplements, it can appear in formulations as a carbohydrate alternative or a marker in certain digestive health tests. It has a lower glycemic index than glucose and is sometimes used in sugar-free products.
In some supplements, especially those targeting endurance athletes or recovery, xylose may be present as part of complex carbohydrate blends to provide sustained energy release without spiking blood sugar significantly.
Although it plays a minor role in sports performance directly, it can be part of specialized carbohydrate formulas intended for gut-friendly energy support.
Synonyms:
Wood sugar
Benefits:
- Provides low-glycemic energy
- May support sustained carbohydrate absorption
- Used in gut absorption tests
Sources:
- Derived from wood, corn cobs, and other fibrous plant materials
- Can be synthesized for supplement use
Observations:
Typically found in carbohydrate blends or specialized sugar-free formulations. High doses may lead to digestive discomfort in sensitive individuals.
