Our body treats Sukrin differently compared to other sugar alcohols (xylitol, maltitol, sorbitol, etc.). Sukrin is the smallest of all sugar alcohols that are known to us and is almost completely (90%) absorbed in the small intestine and excreted unchanged.
The other sugar alcohols are larger and are only partially absorbed in the small intestine. They move on to the large intestine where they are decomposed by bacteria that produce acids and gases. These fatty acids are absorbed as energy by the body. In addition, water is drawn out of the intestines (due to osmotic pressure), which can cause diarrhea.
Sukrin thus differs from other sugar alcohols in that it does not provide energy or stomach discomfort when consumed at normal levels.
