What is it?

Lactitol (beta-galactosido-sorbitol) is a crystalline sugar alcohol and reduced calorie sweetener with a sweetness roughly 40 percent of sugar. Lactitol and lactitol monohydrate are derived from cow's milk (lactose, or milk sugar) and used in the food industry. With a glycemic index of three, lactitol has a negligible effect on blood sugar levels and can be used in diabetic and diet foods. It is also used internationally as an osmotically acting laxative (OsmoAid).[1][2]
