Mannitol is a monosaccharide sugar alcohol. It occurs naturally in plants and may be synthetically produced from fructose or extracted from natural sources. It is used as a humectant, bulking agent, anti-caking agent, sweetener, stabilizer, and thickener.
Mannitol is incompletely absorbed; the mannitol that reaches the large intestine undergoes fermentation by gut bacteria. This may produce gases leading to bloating and other gastrointestinal symptoms. Mannitol is low-glycemic, has 40% of the calories of sucrose, and 50% of the sweetness.
Due to its reduced absorption, consumption in significant quantities (over 20g a day) can cause severe gastrointestinal symptoms including a strong laxative effect.
