D-Arabinitol is a marker for intestinal yeast overgrowth.
Yeast is another class of microbes that can chronically grow in the intestinal tract and cause adverse health effects through the release of toxic metabolites. D-Arabinitol is uniquely produced by intestinal yeast, and the degree of elevation is a useful marker of their growth.
D-Arabinitol is a metabolite of candida, and a high level of this marker is associated with invasive candidiasis. D-arabinitol is produced from dietary carbohydrates when yeasts are rapidly growing in the low oxygen environment of the small intestine.
